Drainage Engineer

Come grow with us.

Balancing the world’s need for safe, reliable water with protecting this critical natural resource for the future requires a deep understanding of interconnected systems.

We work with clients across the entire project life cycle - from initial planning studies through final construction and operations and maintenance services — on both traditional and alternative project-delivery options (design-build, public-private partnerships and financing).

With a robust design and construction division, AECOM offers a unique perspective on designing projects that are fully constructible.

How you’ll make a difference

In this role, you'll join a multidisciplinary Water Resources team and contribute to drainage network modelling and design, and water resources assessments across diverse projects in transport, defence, mining, and energy transition (including wind, solar, and BESS). You’ll collaborate with multidisciplinary teams locally and nationally, while benefiting from mentoring by industry-leading specialists and opportunities to work across NSW and throughout Australia.

This position would likely suit an engineer with 3 - 7 years’ post-graduate experience looking to further develop their technical skills in a collaborative consultancy environment.

In this role, you will mainly support the delivery of drainage modelling and design packages for major transport and civil infrastructure projects. You will work on technically challenging projects that require practical, coordinated, and design-focused solutions across large road corridors.

What you'll be doing

• Undertaking drainage network modelling and design for major road and transport infrastructure projects

• Developing and documenting stormwater drainage systems, including pit and pipe networks, longitudinal drainage and corridor drainage solutions

• Preparing design models, drawings, calculations and technical reports

• Coordinating with broader civil, road, water and multidisciplinary design teams to achieve integrated project outcomes

• Supporting the delivery of projects from planning and concept design through to detailed design

• Contributing to proposal support and maintaining strong client service outcomes

• Continuing to develop your technical skills, project delivery capability and local market knowledge
  

The following qualifications and experience are highly desired, but if you don’t tick all the boxes you could still be a perfect fit for this role. Please apply, all applications will be considered.

The qualities that help you thrive

• Experience delivering work within a consulting, design or engineering environment, ideally 3-7 years

• Demonstrated experience in drainage network modelling and drainage design, particularly for major transport or road corridor projects

• Proficiency in 12d, DRAINS and AutoCAD

• A sound understanding of drainage design principles for linear infrastructure and road corridor environments

• Strong written and verbal communication skills

• The ability to work effectively within multidisciplinary project team

• Familiarity with relevant Australian drainage design standards and guidance

• Exposure to hydrologic or hydraulic assessment tools that support drainage design outcomes
  

Why you’ll love working with us

• Flexible work arrangements, including alternative start/finish times, job-sharing and hybrid work options

• Purchase up to 6 weeks additional annual leave per year

• Volunteer and representation leave

• Flex public holidays – swap Easter or other holidays for ones that suit you better
