Senior Ground Systems Operations Engineer

SWISSto
12 is one of the world’s fastest-growing aerospace companies, evolving from its pioneering use of 3D printing technologies for high-performance Radio Frequency (RF) products and applications to recently announcing the manufacture of entire geostationary telecom satellites, called Humming Sat, that define a new category in space.

Humming Sat is the world’s first commercial telecom GEO Small Sat developed in collaboration with the European Space Agency (ESA). Its uniquely compact size combined with highly capable telecom payloads allows telecommunications operators to deploy a cost-efficient, compact, and agile asset without sacrificing performance or security. Humming Sat has been selected by Intelsat to build the I-45 satellite, by Inmarsat to build three I-8 satellites, and recently by Astrum Mobile to build the NEASTAR-1 satellite.

SWISSto
12 is also a leading provider of Radio-Frequency (RF) products and sub-systems for satellite communication and remote sensing applications. The company’s patented 3D printing technologies and associated product designs are unique to deliver lightweight, compact, highly performing, and competitive RF products.
