What you’ll do

You will act as the technical lead for a small, focused product team building a next‑generation energy modelling platform. You will guide architectural decisions, support engineers day‑to‑day, and help the team deliver high‑quality features at pace.

• Work in a modern, cross‑functional environment with autonomy and the opportunity to take on technical leadership.

• Solve interesting challenges that blend UI, business logic, modelling and AI‑driven behaviour.

• Enjoy the stability of a permanent role while contributing to a long‑term, impactful product initiative.
