Business Area: Freezz

Develop Innovative satellite platforms for telecom constellations. For our locations in Italy and Switzerland Freezz is looking for a versatile Electrical Hardware Engineer to develop units and subsystems for Friisat and other commercial products. The role focuses primarily on design, analyses and test of electrical and electronic hardware for the Friisat spacecraft, from schematic through board and unit-level testing. This position is well suited to an engineer who enjoys working across design development and eventually test hardware at all levels and wants to contribute at multiple levels of a complete the full satellite system.

Why Join Us & Hiring Details

At Freezz you won’t work on a narrow slice of the design: you’ll get your hands on the electronics of a satellite built to fly – and to fly soon, taking your boards from schematic to tested hardware. We take a new approach to building spacecraft: short design-build-test loops, real hardware on the bench early, and decisions made by the people who do the work, from day one and without committee overhead. That means a steep, fast learning curve. You’ll see your schematic become a board, your board go through bring-up and EMC test, and your design head to orbit. And you’ll learn it in a lean, enthusiastic team where building satellites is serious work and real fun, that’s the added value we offer. All of this as part of a European New Space success story backed by ESA and EU programmes.

How to Apply

• Please fill up the application form on this page.
• Where relevant, candidates are encouraged to include examples of technical projects, publications, portfolios, Git repositories, or descriptions of systems they have helped design.
• Freezz welcomes applicants from different backgrounds. Selection decisions are based on professional qualifications, experience, and the requirements of the position.
• We review applications on a rolling basis and respond within 5 business days. We’re actively hiring and moving fast. If you’re a strong fit, expect to hear from us quickly.
