How to Write a Good Trade Job Description
A good trade job description should make the role easy to understand.
That sounds obvious, but plenty of job descriptions are either so vague that they could apply to almost anyone, or so overloaded with requirements that they read like a wish list for a completely different person.
For trade businesses, a job description should explain what the person will actually do, what skills and qualifications they need, who they report to and what success in the role looks like.
It should be useful to candidates, managers and the employee once they start.
That makes it different from a job advertisement.
A job ad is designed to attract applicants. A job description is designed to define the role.
You can use the job description as the foundation for the advertisement, but the two are not exactly the same.
What Is a Trade Job Description?
A trade job description is a written outline of a role within a trade or blue-collar business.
It usually explains the main responsibilities, required qualifications, experience, skills, working conditions and reporting relationships associated with the position.
For example, a job description for a commercial electrician might cover installation work, fault finding, testing, documentation, customer communication and supervision of apprentices.
A diesel mechanic job description might include servicing, diagnostics, repairs, preventative maintenance and breakdown response.
The goal is to give everyone a clear understanding of what the job involves.
Why a Good Job Description Matters
A clear job description can improve several parts of the hiring process.
It helps you write a better job advertisement because you already know exactly what you're recruiting for. It also makes screening easier because you can compare candidates against genuine role requirements rather than making decisions on the fly.
Once someone starts, the description can help set expectations around responsibilities and performance.
For small businesses, this is particularly useful. Roles can easily become vague when everyone simply "does a bit of everything."
A written description provides some structure without turning the business into a corporate bureaucracy.
Start With the Actual Work
Before worrying about job titles or qualifications, start by listing the work the person will actually perform.
Ask yourself what this employee is likely to spend most of their week doing.
If you're hiring a maintenance fitter, that might include inspecting machinery, completing preventative maintenance, diagnosing breakdowns, replacing bearings and mechanical components, and recording completed work.
If you're hiring a carpenter, it could involve framing, fixing, interpreting plans, measuring materials and coordinating with other trades.
Write down the real work first.
You can tidy the wording later.
Avoid Generic Duties
Descriptions such as "perform general trade duties" or "complete tasks as required" don't tell candidates much.
Be specific enough that someone experienced in the trade can picture the role.
Instead of:
"Perform mechanical duties."
Try:
"Complete scheduled servicing, diagnose mechanical faults and repair heavy vehicles and associated equipment."
Instead of:
"Carry out electrical work."
Try:
"Complete commercial installations, switchboard upgrades, fault finding and testing across retail and office projects."
Specific duties help candidates self-select.
Use the Correct Job Title
Choose a title that reflects the actual role.
Examples include:
- Commercial Electrician
- Maintenance Fitter
- Heavy Vehicle Diesel Mechanic
- Qualified Carpenter
- Refrigeration Technician
- Boilermaker
- Landscape Tradesperson
Avoid making the title unnecessarily creative.
Candidates and employees should immediately understand what the role is.
A title such as "Technical Trades Specialist" might sound impressive, but if you really mean "Diesel Mechanic", use the title people recognise.
Add the Specialisation Where It Matters
Many trades cover several different types of work.
A generic "Electrician" description may be too broad if the role is specifically industrial maintenance.
Likewise, "Mechanic" could mean anything from passenger vehicles to heavy mobile plant.
Use a more specific title when the specialisation materially changes the role.
For example:
Industrial Electrician – Maintenance
or:
Diesel Mechanic – Heavy Vehicles
This improves clarity from the beginning.
Write a Short Role Summary
After the title, include a short paragraph explaining the purpose of the position.
This should usually be two or three sentences.
For example:
"The Maintenance Fitter is responsible for completing preventative and breakdown maintenance across production equipment. The role involves fault finding, mechanical repairs, component replacement and supporting the reliability of plant and machinery."
That gives the reader a quick overview before they get into the details.
Focus on the Main Responsibilities
The responsibility section should contain the tasks that genuinely define the role.
You don't need to list every minor thing the employee may ever be asked to do.
Focus on recurring and important duties.
For a trade role, responsibilities could include:
- Completing installations, maintenance or repairs
- Diagnosing faults
- Reading plans or technical drawings
- Using tools and equipment safely
- Recording completed work
- Communicating with supervisors or customers
- Supervising apprentices where relevant
Keep the list relevant.
A job description shouldn't become an inventory of every activity that has happened in the business since 2004.
Separate Essential and Preferred Requirements
This is one of the easiest ways to improve a job description.
Some requirements are essential.
Others are simply helpful.
Putting everything in one giant list makes the role look more demanding than it really is.
For example, a commercial electrician role might have essential requirements such as a relevant licence, driver licence and commercial experience.
Experience supervising apprentices might be preferred rather than essential.
This distinction helps you avoid rejecting capable candidates unnecessarily.
Only Require Qualifications the Role Actually Needs
If the job requires a particular trade qualification, include it.
If it doesn't, don't add one simply because it sounds professional.
For example, a qualified mechanic role should clearly state the relevant trade qualification expected.
A labouring role may not require a formal trade qualification at all.
Keep qualification requirements tied to the work.
Be Accurate About Licences
Some trade work can require specific state or territory licences.
If a licence is genuinely required to perform the role, state that clearly.
Examples may include relevant electrical or plumbing licences depending on the work and jurisdiction.
The same applies to high-risk work licences or other tickets where they are genuinely necessary.
Don't simply copy licence requirements from another company's ad.
Check what your own role actually requires.
Don't Turn the Job Description Into a Ticket Collection
One of the most common mistakes in trade recruitment is listing every licence and ticket the employer could possibly imagine.
If the employee needs a White Card, forklift licence and EWP licence to perform the role, include them.
If one of those would simply be handy occasionally, put it under preferred requirements.
A candidate with the right trade skills shouldn't be ruled out because they don't already hold an easily obtainable ticket that they might use twice a year.
Define the Required Experience Properly
Experience requirements should relate to capability.
Instead of simply saying:
"Minimum five years experience."
Think about what you actually need the candidate to have done.
For example:
"Experience completing commercial electrical installations and fault finding."
or:
"Previous experience servicing and repairing heavy diesel vehicles."
This is more useful than relying solely on years.
Someone with three highly relevant years may be more suitable than someone with ten years in a completely different environment.
Include Technical Skills
For skilled trade roles, explain the technical capabilities needed.
A boilermaker role might require experience in heavy fabrication, interpreting drawings and particular welding processes.
A maintenance fitter role might require experience with bearings, pumps, gearboxes and conveyors.
A mechanic role might require diagnostics, servicing and repair experience on particular vehicle types.
The more specialised the position, the more useful this section becomes.
Include Non-Technical Skills Too
Technical skill is only part of the role.
Depending on the position, you may also need someone who can communicate with customers, work independently, supervise apprentices or complete paperwork properly.
These should be included where genuinely relevant.
Avoid vague phrases such as "excellent communication skills" unless you explain why communication matters.
For example:
"Ability to communicate clearly with customers when explaining faults and completed repairs."
That gives the requirement context.
Explain Who the Role Reports To
A good job description should make the reporting line clear.
The employee may report to:
- Business owner
- Workshop manager
- Site supervisor
- Maintenance manager
- Leading hand
This helps candidates understand the structure of the business.
It also prevents confusion once someone starts.
Include Supervisory Responsibilities
If the employee is expected to supervise apprentices, labourers or other tradespeople, include that in the description.
Don't casually add supervision after someone has been hired if it wasn't part of the original role.
Supervisory responsibility can affect the level of experience you need and the way the candidate views the position.
If it's part of the job, make it clear.
Describe the Working Environment
Trade jobs can vary enormously depending on where the work happens.
A role may involve:
- Workshop work
- Construction sites
- Customer homes
- Industrial facilities
- Mine sites
- Outdoor work
- Regional travel
Include the environment where it materially affects the role.
Someone applying for workshop fabrication may not be interested in spending most of the week travelling to remote sites.
The job description should prevent surprises.
Include Travel Requirements
If the role involves regular travel, state that.
For example:
"Travel between customer sites across Melbourne's south-east is required."
or:
"Role includes occasional regional travel with overnight stays."
For FIFO positions, include the relevant roster and point of hire in the advertisement, while the underlying job description should still explain the nature of the travel and site-based work.
Travel can be a major factor in whether someone wants the job.
Be Clear About Physical Requirements
Some trade roles involve regular lifting, climbing, outdoor work or working in confined spaces.
Where these are inherent requirements of the role, describe them accurately.
Avoid generic statements such as "must be physically fit" if you can explain the actual work instead.
For example:
"The role includes regular manual handling, ladder work and working across active construction sites."
That is more useful and specific.
Include Safety Responsibilities
Safety should form part of most trade job descriptions.
The exact requirements will depend on the workplace, but responsibilities might include following safe work procedures, using personal protective equipment, reporting hazards and complying with site requirements.
For supervisory roles, this section may also include responsibilities for overseeing safe work practices within the team.
Keep it practical rather than filling the description with generic safety language.
Explain Administrative Requirements
Plenty of trade roles involve more paperwork than people expect.
If the employee needs to complete job sheets, service reports, timesheets, inspection records or digital work orders, include that.
This is particularly relevant for service technicians and maintenance roles.
Someone who will spend part of each day documenting work should know that before they start.
Be Honest About Customer Contact
Some tradespeople spend most of their time working around other trades.
Others deal directly with customers every day.
If customer communication is a major part of the role, state it.
For example:
"Explain repair recommendations and completed work directly to customers."
That tells applicants you're not only looking for technical ability.
It also helps you assess communication skills during recruitment.
Include Tools and Equipment Where Relevant
If the role uses specialist tools, machinery or systems, mention them when useful.
For a mechanic, this might include diagnostic equipment.
For a machinist, it could include CNC machinery.
For a maintenance technician, it might involve computerised maintenance management systems.
You don't need to list every screwdriver in the workshop.
Focus on tools and equipment that help define the position.
Describe What Good Performance Looks Like
A strong job description can also explain the outcomes expected from the role.
For example:
- Complete work safely and to required standards
- Diagnose faults accurately
- Meet reasonable project or service deadlines
- Maintain clear job records
- Communicate effectively with customers and supervisors
This helps turn a list of duties into a clearer picture of performance.
Don't Use "Other Duties as Required" as the Entire Description
It's reasonable to acknowledge that roles evolve and employees may occasionally assist with other appropriate work.
But don't use that phrase to avoid defining the position.
The employee should still understand their primary responsibilities.
A description with three vague duties followed by "and anything else management requests" isn't particularly useful.
Keep the Language Straightforward
Trade job descriptions should be written in plain English.
Avoid corporate language where a simpler sentence would do.
Instead of:
"Drive operational efficiencies through proactive maintenance activities."
Write:
"Complete preventative maintenance to reduce equipment breakdowns and downtime."
The second version tells the person what they're actually expected to do.
Avoid Meaningless Personality Requirements
Requirements such as "must be a superstar", "must have a can-do attitude" or "must be passionate about excellence" are hard to assess and don't add much.
If you're trying to describe a genuine behaviour, be specific.
Instead of:
"Must be a team player."
Try:
"Work closely with apprentices and other trades to complete projects safely and efficiently."
That is something you can actually discuss during an interview.
Don't Copy and Paste Another Company's Job Description
Looking at other job descriptions can help with ideas.
But simply copying one creates problems.
Their role may involve different duties, qualifications, equipment and working conditions.
Start from your own business and the work you actually need performed.
A smaller, accurate description is far more useful than a polished document describing somebody else's job.
Review the Description With Someone Who Does the Work
If you're not currently performing the role yourself, speak to someone who is.
A tradesperson already doing similar work can quickly identify missing responsibilities or unrealistic requirements.
This is especially useful for larger businesses where HR or management may be writing descriptions for technical positions.
Ask:
"Does this actually sound like your job?"
You may get some surprisingly useful feedback.
Keep Job Descriptions Updated
Roles change.
Businesses grow, equipment changes and employees take on new responsibilities.
Review your job descriptions periodically, particularly before recruiting again.
If a document hasn't been updated in six years, there's a good chance it no longer reflects the actual role.
Updating it before advertising can prevent you from recruiting against outdated expectations.
Job Description vs Job Advertisement
These terms are often used interchangeably, but they serve slightly different purposes.
The job description defines the position.
The job advertisement sells the opportunity.
Your job description might include detailed responsibilities, reporting lines, technical requirements and internal expectations.
The job ad usually takes the most important parts of that information and presents them in a way that encourages suitable candidates to apply.
You don't necessarily need to publish the full internal job description as the advertisement.
Use it as the foundation.
Example Trade Job Description Structure
A practical trade job description can follow this format.
Job Title
Use the recognised occupation and specialisation.
Role Summary
Write a short paragraph explaining the purpose of the position.
Key Responsibilities

Essential Requirements
The role may require the relevant electrical qualification and licence, a driver licence and suitable commercial electrical experience.
Preferred Requirements
Experience supervising apprentices, fault finding or working on specific commercial systems may be preferred depending on the business.
Example: Diesel Mechanic Job Description
Role Summary
The Diesel Mechanic is responsible for servicing, diagnosing and repairing heavy vehicles and associated equipment in accordance with workshop and safety requirements.
Key Responsibilities
Typical duties may include scheduled servicing, mechanical repairs, fault diagnosis, component replacement, preventative maintenance and completing workshop documentation.
Essential Requirements
Relevant mechanical trade qualifications, suitable heavy vehicle experience and a driver licence may be required depending on the position.
Preferred Requirements
Experience with particular truck brands, diagnostic systems or heavy equipment may be useful.
Example: Maintenance Fitter Job Description
Role Summary
The Maintenance Fitter supports the reliability of production equipment through preventative maintenance, fault finding and mechanical repairs.
Key Responsibilities
Work may include inspecting plant, diagnosing breakdowns, replacing mechanical components, maintaining pumps and gearboxes, assisting with shutdown work and recording maintenance activities.
Essential Requirements
A relevant mechanical trade qualification and experience in an industrial maintenance environment may be required.
Preferred Requirements
Experience with particular plant, machinery or maintenance systems may be beneficial.
Example: Boilermaker Job Description
Role Summary
The Boilermaker is responsible for fabrication, welding, repair and maintenance work across structural or heavy industrial projects.
Key Responsibilities
Duties may include interpreting fabrication drawings, preparing materials, welding and fabricating components, completing repairs and inspecting completed work.
Essential Requirements
A relevant fabrication trade qualification and suitable welding and fabrication experience may be required.
Preferred Requirements
Additional experience with particular welding processes, mining equipment or site work may be beneficial depending on the position.
Example: Qualified Carpenter Job Description
Role Summary
The Carpenter completes construction and carpentry work across residential or commercial projects in accordance with plans, project requirements and safety procedures.
Key Responsibilities
Work may include measuring and setting out, framing, fixing, installation, interpreting plans and coordinating with other trades.

Example: HVAC and Refrigeration Technician Job Description
Role Summary
The HVAC and Refrigeration Technician is responsible for servicing, maintaining, diagnosing and repairing air conditioning and refrigeration systems.
Key Responsibilities
Typical work may include preventative maintenance, fault diagnosis, equipment repairs, commissioning, customer communication and completing service documentation.
Essential Requirements
Relevant trade qualifications, licences and experience appropriate to the work should be included.
Preferred Requirements
Experience with particular commercial, industrial or refrigeration systems may be preferred.
Example: Apprentice Job Description
Apprentice descriptions should be written differently from qualified trade roles.
You're hiring someone to learn.
The job description should focus on assisting qualified tradespeople, completing structured training, following safety procedures, developing practical skills and attending required off-the-job training.
Avoid requiring extensive experience for an entry-level apprenticeship.
A first-year apprentice isn't supposed to already know how to do the job independently.
That's what the apprenticeship is for.
How Detailed Should a Trade Job Description Be?
It should be detailed enough to explain the role properly without becoming unnecessarily long.
A straightforward trade position might only need one or two pages internally.
A senior technical or supervisory role may require more detail.
The key question is whether someone reading the description can understand what the employee will spend their time doing and what is expected of them.
If the document is long but still doesn't answer that question, adding more words isn't the solution.
Common Trade Job Description Mistakes
One common mistake is being too vague. Another is listing unrealistic requirements that aren't actually necessary.
Employers also sometimes confuse a job description with a job advertisement and fill it with marketing language rather than defining the role.
Other problems include outdated responsibilities, incorrect licence requirements, unclear reporting lines and job descriptions that don't reflect what employees actually do.
The best descriptions are accurate, practical and easy to understand.
Use Your Job Description to Improve Recruitment
Once the description is complete, use it to create the job advertisement.
Pull out the most important duties, essential requirements and benefits. Add the salary, location, working hours and reasons someone should consider your business.
This creates consistency between what you advertise and what the person actually does after they're hired.
That matters.
Nothing damages a new employee's confidence faster than starting a job and discovering that the role is completely different from the one they applied for.
Use the Description During Interviews
A good job description also makes interviewing easier.
Take each important responsibility and think about how you can assess it.
If the role requires fault finding, ask candidates to describe fault-finding work they've completed.
If the role includes supervising apprentices, ask about previous supervisory experience.
If customer communication matters, discuss situations where they've had to explain technical work to customers.
The description effectively becomes a checklist for assessing candidates.
Use It During Onboarding
Once the employee starts, go through the role with them.
Explain the key responsibilities, reporting line, expectations and any areas where they'll receive training.
This creates clarity from the beginning.
It also gives the employee an opportunity to ask questions before assumptions become problems.
Final Thoughts
A good trade job description should be practical.
It doesn't need corporate language, excessive detail or an enormous list of qualifications.
It needs to explain what the person will do, what they genuinely need to know, what qualifications or licences are required and how the role fits within your business.
Start with the real work. Be specific about duties. Separate essential requirements from nice-to-haves. Use straightforward language and review the description with people who understand the role.
Then use that document as the foundation for your job advertising, interviews and onboarding.
A good job description won't magically find you the perfect tradie.
But it will make it much easier to know who you're looking for when they apply.
Frequently Asked Questions
What should be included in a trade job description?
A trade job description should usually include the job title, role summary, key responsibilities, essential qualifications, required licences, relevant experience, reporting line and working environment.
