Delivering Stability Today.
Developing Capacity for Tomorrow.

We promise a place where your talent powers change — where ambition meets purpose, and together we lead the charge toward a sustainable energy future.
At S4 Energy, you help build the energy systems of tomorrow.
We share a mission: to power progress through people who believe in what they do and deliver on what they promise.
Every person here plays a vital role in shaping the future of energy storage — from the first design sketch to the operational heartbeat of our battery parks.

Opportunities at S4 Energy

We are always looking for people who combine strong technical understanding with a clear sense of responsibility for what they deliver.

At S4 Energy, the choices you make shape how assets are built, operated, and perform over time.

Because we own and operate our assets, you will work across the full value chain, from early-stage origination and development through to construction, operations, and trading. Whether you work in engineering, commercial, or operational roles, you will see work turn into infrastructure and take ownership of how systems perform over time.

We are building projects that play a real role in Europe’s energy transition. Explore our open positions, or contact us directly if you want to contribute your skills to work that matters.

In the end, we always find a solution – that’s the beauty of the S4 mindset.”
