Senior Product Software Engineer

If you’re interested in working on complex software problems that have a real-world impact, this role could be a great fit.

Elysia Battery Intelligence is building software that helps manage large-scale battery systems, a key part of the global clean energy transition. These systems generate huge amounts of data, and Elysia’s platform turns that data into real-time insights to help operators run them safely and efficiently.

The engineering team comes from Zitara, where they spent seven years developing advanced systems for safety-critical and high-performance applications. Now at Elysia, they’re applying that experience to grid-scale battery storage - something that hasn’t existed before.

Backed by Fortescue, one of the world’s largest green energy companies, the team is building a platform that processes hundreds of thousands of data points per second and feeds actionable control signals back to energy operators.
