Job description

About Morson Edge

Morson Edge is a specialist recruitment consultancy connecting engineering professionals with leading businesses across the built environment. We work closely with building services consultancies throughout Australia, offering opportunities across permanent and contract positions.

About the Company

Our client is an established building services engineering consultancy in Sydney with a strong background in mechanical and electrical design. Working across residential, mixed-use and commercial developments, they have a solid pipeline of projects and are looking for an experienced Senior Mechanical Design Engineer to provide additional technical capability to their team. This is an initial 3-month assignment, with work expected to continue for at least 6 months and potential to extend further.

About the Role / Duties

You’ll take responsibility for leading mechanical services design, working alongside an established engineering team with drafting support available.

• Leading HVAC design across residential and mixed-use projects.
• Undertaking mechanical engineering calculations, equipment sizing and selection.
• Managing detailed design and construction documentation.
• Coordinating and reviewing work produced by drafting and modelling teams.
• Liaising with architects, engineers and other project stakeholders.
• Resolving technical design challenges and ensuring compliance with Australian Standards and the NCC.
• Delivering accurate, coordinated designs with minimal supervision.

Skills & Experience

• Strong mechanical building services design background, ideally at Senior Engineer level.
• Australian Class 2 residential experience is highly desirable.
• Strong international design experience from the UK, NZ or Europe will also be considered.
• Sound technical knowledge of HVAC systems, calculations and design documentation.
• Experience leading design delivery with drafting support.
• Comfortable working independently and taking ownership of technical decisions.
• Availability at short notice would be advantageous.
• Registered Design Practitioner status is not required, as regulated design sign-off will be handled separately.

Culture

This is a technically focused consultancy where engineers are trusted to take ownership of their work. The team values practical engineering knowledge, clear communication and people who are comfortable taking responsibility without needing constant direction. You’ll be working alongside experienced engineers in a collaborative environment, with support available where needed, but the expectation is that you can contribute independently from the outset. They’re looking for someone who is approachable, reliable and happy to get involved in the detail rather than simply oversee others.

Benefits to You

• Competitive hourly rate based on experience.
• Initial 3-month assignment with a strong likelihood of extension to 6 months and potentially 12 months.
• Opportunity to work on established residential and mixed-use developments.
• Technical ownership of design with drafting support available.
• Join an established consultancy without committing to a permanent move.
• Casual employment or eligible Pty Ltd contracting arrangements available.
• Weekly pay for casual employees through Morson Edge.
• Potential for a longer-term opportunity depending on project requirements.
