Senior Design Engineer - Water & Wastewater Infrastructure

Innova Water Pty Ltd

Ascot, Brisbane QLD

$135,000 - $155,000 + Super

Design. Procurement. Construction. Commissioning.

Most engineering consultancies design projects.

At Innova Water, we help deliver them.

We are a specialist water and wastewater infrastructure consultancy providing process engineering, hydraulic design, design management, procurement support, commissioning assistance and technical project delivery services across Australia's east coast.

Unlike many traditional consultancies, our team combines process design expertise with extensive real-world construction, commissioning and project delivery experience. This allows us to provide practical engineering solutions that consider how infrastructure will actually be procured, built, commissioned and operated.

As a result, our clients engage us for far more than traditional design services. We regularly support projects through:

- Concept development and feasibility studies
- Process and hydraulic design
- Design management and coordination
- Procurement and vendor selection
- Construction support
- Commissioning and optimisation
- Proof of Performance (PoP) testing
- Operational handover and training

As our business continues to grow, we are seeking an experienced Design Engineer or emerging Senior Design Engineer who can take ownership of projects, work directly with clients and continue developing their technical and project delivery capabilities.
