About the Role: 

Our Design Engineers deliver designs from concept to IFC and support commissioning to ensure successful, sustainable water and wastewater infrastructure across Australia.

You will play a key role in ensuring the fit for purpose performance of assets including desalination plants, water and wastewater treatment facilities, pumping stations, and related infrastructure. You will contribute to both new infrastructure and complex brownfield upgrades, applying your specialist expertise to deliver effective, practical solutions.

This role requires the ability to manage multiple projects concurrently, supported by proven Australian experience in HV, LV, and field instrumentation, as well as water industry systems such as pump control, power supply, and variable frequency drives. Significant industry experience is essential; this position is not suitable for graduate engineers.

Key responsibilities include:

• Work collaboratively with a wide range of stakeholders across Australia, applying strong communication and negotiation skills to meet project and client objectives. 
• Partner with design drafters, design managers, and project managers to ensure designs are delivered on time and within budget. 
• Produce engineering designs that comply with client specifications, relevant standards, and legislative requirements. 
• Apply risk management principles to deliver designs that meet quality, safety, and environmental expectations, including the use of SID, HAZOP, CHAZOP, and CHAIR methodologies, and integrating appropriate preventative and mitigative measures. 
• Support construction and commissioning teams by developing commissioning documentation and providing day to day technical assistance to facilitate seamless project delivery.

About you:

Our ideal candidate will be enthusiastic about designing and delivering the best possible infrastructure solutions for each unique project. Your significant technical competence and ability to work both independently and in a team environment will allow you to successfully contribute to the delivery of a diverse range of exciting water infrastructure projects across Australia.

You will bring:

• Bachelor’s degree in Electrical Engineering; CPEng preferred. 
• Minimum seven years’ experience in the water industry or a related field. 
• Strong knowledge and demonstrated design application experience of Australian Standards and proficiency with AutoCAD and PowerCAD. 
• Experience developing and reviewing LV and ELV designs; HV experience beneficial. 
• Essential expertise in designing power distribution systems, control panels, and MCCs, including performing load calculations, fault current analysis, and protection coordination studies. 
• Ability to produce clear, accurate technical documentation, including Basis of Design, control philosophies, methodologies, and scopes of work. 
• Excellent communication skills with both technical and non technical stakeholders. 
• Hands on experience in water infrastructure design or operations (highly regarded).
