Full Job Description

What if your next role helped shape the future of water in Australia?

At WSP, we don’t just design infrastructure — we redefine how communities connect with water. Join a global network of experts, contribute to landmark projects, and do the kind of work the world truly needs. Here, curiosity is celebrated, ideas are welcomed, and careers are shaped as uniquely as the people behind them.

Our Water team partners with governments, utilities, developers, and industry to deliver innovative, sustainable, and future‑ready solutions across Australia. From concept to completion, we are transforming how water infrastructure supports communities, economies, and the environment.

We are seeking an Principal Mechanical Engineer to join our Melbourne team, placing you at the forefront of some of Australia’s most transformative water infrastructure programs.

The Opportunity

We recognise that everyone brings unique strengths. While experience in the water sector is highly valued, we also understand that careers develop in different ways. Whether you are operating at Associate or Principal level , we will shape the role around your technical strengths, career aspirations, and long‑term goals.

In this role, you will:

Drive the technical quality of water and wastewater infrastructure design projects.
Lead mechanical and hydraulic design across the full project lifecycle.
Produce and review high‑quality technical documentation and contribute to proposals and pursuits.
Manage and coordinate design requirements across multiple projects or program work packages.
Lead design packages across a diverse portfolio of water infrastructure projects. Experience in D&C packages highly regarded.
Collaborate within a responsive, client‑focused design team to exceed project expectations.
Support project and design management activities.
Mentor emerging engineers and collaborate across local and national teams.

About You

You are a qualified and experienced Mechanical Engineer with a passion for water infrastructure and a collaborative, solutions‑focused mindset.

Ideally, you bring:

A Bachelor’s degree in Mechanical Engineering (or equivalent).
Chartered status (CPEng).
Proven experience (15 years+) in engineering consultancy or design roles for contractors or asset owners, with essential experience in the water sector .
Strong technical capability across water infrastructure and treatment systems.
Hands‑on experience in hydraulic design (e.g. water utilities, pump stations); exposure to CFD or pipe stress analysis is advantageous.
Confidence in equipment selection and specification for complex systems.
Proficiency in stress analysis using software tools or analytical methods.
Familiarity with Plant 3D or Inventor (advantageous).
Knowledge of CHAIR, HAZOP, and Safety‑in‑Design practices.
Strong communication skills, with the ability to prepare and review technical reports and work effectively with clients and internal teams.

Why Choose WSP?

At WSP, you’ll find a workplace where you’re supported, empowered, and inspired to grow. We offer:

Competitive remuneration and flexible working arrangements.
Clear career pathways, including mentoring, leadership development, and national or global secondment opportunities.
An inclusive culture that values diverse perspectives and encourages you to bring your whole self to work.
Meaningful, purpose‑driven projects that help shape the future of water.
Benefits including paid parental leave, purchased leave options, global mobility opportunities, and more.
Access to our Employee Share Purchase Plan , allowing you to become a vested partner in WSP’s success.

Here, you’ll find more than just a role — you’ll find a place to thrive, grow, and make an impact .

Imagine a better future for you, and a better future for us all.

With us, you can.
