We're recruiting on behalf of an exciting new entrant to the Australian battery energy storage (BESS) market — a well-backed OEM start-up building out its local team from the ground up in Sydney.
They're initially focused on delivering Commercial & Industrial (C&I;) BESS projects, with a clear roadmap to expand into utility-scale developments as the business scales locally.

Solutions engineering, technical sales, or project engineering experience within C&I; energy storage
Comfortable working autonomously in a start-up environment, wearing multiple hats as the business scales
Robust communication skills — able to translate technical detail for both clients and internal stakeholders
Genuine interest in growing with a business as it moves from C&I; into utility-scale delivery
Based in or willing to be based in Sydney
