Materials and Processes Test Engineer

SWISSto12 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 HummingSat, that define a new category in space.

HummingSat is the world’s first commercial telecom GEO SmallSat 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. HummingSat 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.

SWISSto12 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.

This position is a unique opportunity to play a key role in the development, qualification, and control of advanced materials, manufacturing processes, and hardware for the aerospace industry. The Test Engineer will work closely with the Materials & Processes, Manufacturing Engineering, Quality, and Production teams to plan, execute, and oversee testing activities that support product development, qualification, and production. Beyond the execution of tests, the Test Engineer will be responsible for managing laboratory operations, developing and maintaining test procedures, ensuring equipment readiness, and delivering high-quality test data and technical reports to internal stakeholders. This position is ideal for a hands-on engineer who enjoys laboratory work, technical problem solving, process improvement, and taking ownership of laboratory capabilities and resources.
