• Coordinate with internal stakeholders, project managers, field teams, and contractors to deliver fit-for-purpose solutions safely and on schedule
• Contribute to HAZOPs, constructability reviews, risk assessments, and lessons learned sessions
• Assist in ensuring asset information is accurately captured and handed over into operational systems following project completion
• Support the growth and development of the engineering team, helping to build tools, templates, and processes that enhance team capability and project delivery
