With a growing pipeline of projects, including onshore wind, solar, and battery storage, Atmos is committed to being the partner of choice for communities, landowners, and energy buyers. As a dynamic and lean organisation, Atmos Renewables seek professionals who align with their company values and thrive in a collaborative, team-driven setting.

About The Role An exiting opportunity for an IT Systems Engineer to join the Atmos Renewables team and play a key role in supporting and evolving our corporate IT setting.

The position is based in our Sydney office, with a regular monthly visit to the Melbourne office and periodic travel to Atmos’ renewable energy sites across regional Australia to support operational technology (OT) environments.
