Mechanical Engineer

The Opportunity

At APA, our purpose is to secure Australia’s energy future. We’re not doing it alone. We’re doing it with our customers and communities as Australia’s energy infrastructure partner, a role our unique experience and expertise positions us to play.

We now have an exciting opportunity for a Mechanical Engineer to join our Infrastructure Delivery team on a full‑time, permanent basis.

Reporting to the Manager Development Engineering, you will play a critical role in shaping the earliest stages of APA’s gas infrastructure programs in a front‑end, concept-focused capacity. You will provide high‑level mechanical and pipeline engineering leadership that frames project direction, screens technical options, and establishes the preliminary design foundations for major infrastructure decisions. Your work will ensure mechanical solutions are viable, safe, and optimised for FEL‑1 (Concept) and FEL‑2 (Select) gates, forming the technical basis that will later guide detailed engineering teams.

The location for this role is flexible and hybrid, and we welcome applicants from across Australia.

Key Responsibilities

• Deliver high‑level mechanical and pipeline engineering artefacts required for FEL‑1 and FEL‑2, focusing on concept definition, technical screening, and early‑stage feasibility

• Evaluate mechanical options at a conceptual level, assessing constructability, operability, safety, equipment suitability, layout constraints, and cost‑efficiency

• Lead the development of preliminary Mechanical and Pipeline Design Specifications and input to the Preliminary Design Basis

• Drive early‑stage integrity and safety considerations, leading mechanical input into MCA studies and identifying potential fatal‑flaw risks before Select gate

• Integrate lean design principles, emissions‑reduction opportunities, and future‑fuel considerations into early mechanical configurations

• Ensure concept‑level designs align with APA and Australian standards and establish pathways for compliance for new or emerging technologies

• Represent mechanical engineering in early risk workshops (HAZID, SID, emissions screening), shaping concept direction and risk posture

• Collaborate with Concept Study Leads, Front‑End Design, and multidisciplinary stakeholders to ensure mechanical inputs align with study schedules and strategic needs

• Contribute to engineering consistency by developing templates, guidelines, and lessons learned specific to concept‑level mechanical design

Your background

• Deep understanding of mechanical and pipeline engineering with strong experience in front‑end concept or feasibility‑stage engineering

• Proven ability to define mechanical scope and high‑level configurations without requiring detailed design, calculations, or complex modelling
  Skilled in identifying technical, constructability, and operability risks early in the lifecycle

• Experience leading mechanical inputs into FEL‑1 and FEL‑2, including option screening, early configuration development, and conceptual layout considerations

• Strong capability in representing mechanical engineering in multidisciplinary risk workshops

• Ability to apply lean design, emissions‑reduction principles, and innovative solutions at the conceptual stage

• Excellent stakeholder engagement skills, with the ability to influence and align mechanical direction across engineering, commercial, and regulatory groups

About the Team

The Concept Engineering & Research team is a specialised group that shapes the earliest stages of APA’s major infrastructure projects. They develop high‑quality feasibility studies and forward‑thinking engineering concepts that guide strategic decisions, ensuring every project begins with clear, commercially sound, and technically robust foundations.

They also lead APA’s gas infrastructure research and innovation agenda, driving future‑fuel readiness and integrating emerging technologies and global best practice. Known for their technical depth, curiosity, and strong collaboration across the business, this team plays a crucial role in steering APA’s long‑term infrastructure strategy.
