About H55

H55 is the electric aviation pioneer born from Solar Impulse, the first aircraft to fly around the world on solar energy alone. Our mission is to make air transport clean, safe, and affordable by building the certification grade energy storage the industry needs to scale.

What we build is meant to fly. Not just prototypes, but certified systems that work in real operations. That requires discipline across engineering, safety, and how we run the business, including finance.

We are based in Sion, with a growing international footprint, and we are entering a pivotal new phase, expanding our operations and building the foundation for the next stage of electric aviation.

Your Role

Reporting to the CFO, you will be a core member of a small, hands on finance team. There is no large back office behind you. You own your topics end to end, from transactions through to reporting, and you make things work in practice.
