Senior Mechanical Project Engineer

The Company

Join a national mechanical contracting business that delivers tailored building services, energy upgrades and asset replacement programs for major portfolios across Australia’s east coast. You’ll work on fit-outs, refurbishments and capital replacement projects, collaborating closely with project, estimating and service teams. The culture is down-to-earth, collaborative and technically sharp, led by people who still love solving real engineering challenges.

What you’ll be doing

• Be the technical authority. Lead HVACR design and compliance validation; scope, design and certify air/water/HVACR systems; provide guidance on code compliance and engineering best practice.

• Deliver end-to-end solutions. Support projects from feasibility through to commissioning, ensuring technical integrity, constructability and operational performance.

• Champion practical decarbonisation. Model building loads, evaluate gas-to-electric pathways, and guide refrigerant transitions with a whole-of-life lens.

• Provide assurance, not sales. Focus on technical leadership, risk mitigation and engineering excellence, not chasing bids or winning work.

• Collaborate with clients and peers. Engage confidently with consultants, facility managers and project teams to ensure effective, safe and efficient delivery.

What you’ll bring

• Registration to sign off designs (e.g., CPEng plus state registration such as BPV/NER) and 10+ years across mechanical contracting.

• Strong technical background in HVACR design, certification and risk assessment; comfortable coordinating external drafting/BIM and commissioning partners.

• Skilled communicator with the ability to influence and explain design choices clearly to both engineers and non-technical stakeholders.

• Nice-to-haves: NABERS/Green Star experience, commissioning oversight, and knowledge of CAMEL and Bluebeam.

What’s in it for you

• A true SME mandate: Step into the role vacated by a long-tenured technical leader and help shape national standards.

• Tangible impact: Work on live buildings where smart engineering decisions improve efficiency, sustainability and client outcomes.

• Supportive team: Estimating, project and service teams aligned around quality, safety and smooth delivery.

• Growth runway: Influence engineering practices nationally, mentor peers and drive improvement initiatives.

• Flex that grows with trust: Office-first early on; hybrid once established.

• Package: $160k–$180k base + super (around $200k TRP), with scope to stretch for an outstanding hire; novated lease options available.

Hiring process

Two stages: (1) Technical/fit with the National Engineering leader and relevant state manager; (2) final with the Managing Director.
