Engineering Manager / Senior Engineer - Helical Pile Foundations

Solidity is an Australian manufacturer of true helical screw piles. Since 2016 we have designed, manufactured and installed screw pile foundations, with our own robotic manufacturing cell, in-house engineering and testing, and site installation teams. Our team of around 40 supplies projects across Australia, with a growing focus on battery storage, solar and transmission infrastructure.

In 2026, Solidity won the Renewable Energy Manufacturer category at the Australian Manufacturing Awards.

About the role

We're looking for an Engineering Manager or Senior Engineer to lead our internal engineering function. You'll own design and certification on every project, from first enquiry and tender through to as-built sign-off, across industries from transmission infrastructure to modular construction, and lead our engineering team.

You’ll report to the Managing Director and work closely with our business development, projects delivery, manufacturing and quality teams. The level of appointment will depend on your experience.

What you’ll do

Manage engineering outcomes for projects across a range of industries, from transmission infrastructure to modular construction

Own all design, testing and geotechnical engineering for Solidity's supply-only and supply-and-install projects

Provide engineering support to Solidity Installation Partners nationally

Design helical pile foundations to AS 2159 and project specifications, and certify the work of the engineering team

Prepare and approve estimates, quotes and tenders with our National Business Development Manager

Assess geotechnical data, specify site investigations and set design parameters

Plan and oversee pile load testing, and review results against the design

Deliver the engineering on each project, including drawings,



manufacturing specifications, installation methodology, testing and set-out, and give site teams technical direction

Use, champion and help develop the Solidity Engineering Toolkit, our in-house design software

Maintain engineering procedures in our integrated management system with our Quality Manager

Lead, develop and mentor the engineering team

What you’ll bring

A degree in civil, structural or geotechnical engineering

8+ years (Engineering Manager) or 5+ years (Senior Engineer) in foundation or geotechnical design, ideally deep foundations or piling

CPEng, NER or RPEng, and registration as a professional engineer in Victoria, or eligibility to obtain it

Willingness to register in other states as our work requires

Experience preparing estimates and tenders

Working knowledge of AS 2159

A driver's licence, and willingness to travel interstate and work on site

Helical or screw pile design experience

Foundation design for battery storage, solar or transmission projects

Experience leading an engineering team

Own the engineering, end to end. Lead the engineering function of an award-winning manufacturer, reporting directly to the Managing Director. Your calls shape the product, the tender and the outcome on site.

See your designs built. We design, manufacture and install our own piles, so your work goes from the screen to our robotic manufacturing cell to the ground, and you see the whole loop.

Real variety. Transmission lines, battery storage and solar farms, through to modular and commercial buildings, across every state.

Put data behind the design. Work with our university research partners to turn installation and load test data into better design methods.

Be properly rewarded. A market-competitive salary plus super, your professional registrations paid in every state you need, and support for your professional development.
