Commissioning Engineer - Solar & BESS (Germany)

I'm currently partnered with a well-established renewables developer active across the full project lifecycle—from the acquisition of project rights through to construction and long-term delivery. Their focus is on creating sustainable, economically viable energy projects tailored to long-term success.

The company has a strong footprint in Europe and is entering a significant growth phase, with plans to develop and bring online 1 GW of renewable energy projects over the next three years. This will be achieved through a mix of in-house delivery and strategic partnerships, positioning them as a key player in Europe’s clean energy transition.

This is an excellent opportunity for professionals who want to contribute to meaningful renewable energy development at scale, within an ambitious and well-backed organisation.

As a Commissioning Engineer – BESS, you will be responsible for the planning, execution, and documentation of the commissioning process for utility-scale energy storage systems.
