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 systems the industry needs to scale.
What we build is meant to fly. Not just prototypes, but certified systems that operate in real-world conditions. That requires discipline across engineering, safety, and the way we run the business.
Based in Sion, Switzerland, with a growing international footprint, H55 is entering a pivotal new phase as we expand our operations and build the foundation for the next stage of electric aviation.
About the Role
We are looking for an IT Application Specialist with a strong foundation in system administration. As part of the IT team, you will be the go-to person for keeping our business applications and web services running smoothly, from day-to-day operations to full software lifecycle ownership across the organisation.
You will ensure service continuity, manage user access, support end-users, and contribute to IT projects. Your ability to document what you build and maintain will be as valued as your technical skills.
