Job description

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.

We are seeking a highly motivated senior DSP engineer to join our team to help develop, design, implement, and test advanced FPGA based deployments for high-performance communications payloads. The ideal candidate will have deep experience with signal processing algorithm development relative to software defined radios and communications systems, as well as practical implementation experience on the latest FPGA and System on Chip platforms. This role requires strong technical ownership, hand-on development capabilities and the ability to translate system level requirements into executable code.
