Professional Civil Engineer (Civil / Site Infrastructure) – 2 to 5 years post-graduate

We’re looking for a developing civil engineer to support the delivery of site infrastructure design packages across a range of projects. You’ll contribute to stormwater, earthworks and basic water/wastewater designs, coordinate with other disciplines, and build strong technical fundamentals under the guidance of senior engineers.

What you’ll be doing

• Perform specific and limited portions of broader civil/site infrastructure assignments under moderate supervision, to agreed budget and programme.
• Gather, interpret and correlate engineering data using established and well-defined procedures.
• Work on detailed or routine design tasks involving calculations, modelling and relatively simple tests/checks.
• Support delivery of key infrastructure elements, including:

  • Stormwater design (pit and pipe layouts, hydraulic checks, minor drainage design)

  • Bulk earthworks support (grading plans, levels coordination, basic cut/fill inputs)

  • Basic water and wastewater infrastructure (reticulation layouts, tie-ins, design checks)

  • WSUD support where required (e.g., contributing to concept layouts and design documentation).

• Propose practical approaches to new problems, escalating early where needed and applying learnings from previous tasks.
• Identify discrepancies in calculations, drawings, models or inputs and raise them promptly for resolution.
• Coordinate with internal disciplines and external stakeholders on interfaces (services coordination, site constraints, constructability).
• Provide day-to-day support and informal guidance to graduates/entry-level engineers (as appropriate).

What we’re looking for

• 2–5 years’ post-graduate experience in civil/site infrastructure design.
• Exposure to applying Austroads and local council/authority requirements (or a willingness to learn quickly).
• Developing competency in stormwater (pit and pipe) and familiarity with earthworks and basic water/wastewater design tasks.
• Interest in WSUD principles and how they integrate with stormwater solutions (a plus).
• Any exposure to Department of Defence projects is highly regarded, but not essential.
• Process-driven and detail-oriented, with a clear focus on quality, checking and well-structured deliverables.
• A collaborative mindset, comfortable working in multidisciplinary teams and asking the right questions early.
