Job Description
SWISSto12 is one of the world’s fastest-growing aerospace companies, specializing in 3D printing technologies for high-performance Radio Frequency (RF) products and applications. The company is expanding into manufacturing entire geostationary telecommunication satellites, called HummingSat, which have already been sold to leading telecom operators such as Intelsat and ViaSat.
HummingSat is the world’s first commercial GEO SmallSat developed in collaboration with the European Space Agency (ESA). Its compact size and advanced telecom payloads enable cost-efficient, agile, and secure satellite deployment.
SWISSto12 is also a leading provider of RF products and sub-systems, utilizing patented 3D printing technologies to create lightweight, high-performance RF components. This role offers a unique opportunity to lead the development of a new class of telecommunication satellites.
If you seek a position where you can contribute to an innovative and rapidly growing company, this role is ideal. It provides a key opportunity to support the industrialization and production of advanced space hardware during a critical growth phase. As a Materials & Process (M&P) Engineer, you will focus on maturing, stabilizing, and optimizing materials and manufacturing processes to ensure successful transition from prototype to flight-ready systems.
You will support production teams, contribute to process development and continuous improvement initiatives, and lead the qualification of critical technologies such as additive manufacturing (SLM) of aluminum. Your efforts will be vital in enabling reliable, efficient, and repeatable manufacturing of high-performance spacecraft structures and subsystems.
Job Requirements
* Master’s degree in Materials Science, Aerospace Engineering, Mechanical Engineering, or related field.
* Strong expertise in additive manufacturing (SLM) with aluminum alloys, including process development and industrialization.
* Experience supporting production environments and scaling processes for higher throughput.
* Understanding of space-specific challenges (thermal cycling, vacuum compatibility, outgassing, radiation).
* Familiarity with industry standards (ECSS, NASA-STD, ASTM, MIL-specs).
* Hands-on experience with design-for-manufacturing and process optimization techniques (e.g., SPC, PFMEA, Lean/6σ tools).
* Experience with launch vehicle or spacecraft hardware production.
* Knowledge of material testing, outgassing control (ASTM E595), and environmental qualification methods (TVAC, vibration).
* Excellent analytical, communication, and cross-functional collaboration skills.
* Comfort working with tight timelines, multiple time zones, and frequent travel.
* Outstanding English writing and presentation skills; knowledge of French is a plus.
Job Responsibilities
* Drive the industrialization of materials and manufacturing processes to ensure stability and repeatability for serial production in a spaceflight environment.
* Support daily production activities, providing expertise to resolve issues and improve yield.
* Lead continuous improvement initiatives to reduce costs, cycle times, and non-conformances while maintaining quality.
* Collaborate with design, manufacturing, and quality teams to meet mission and production requirements.
* Characterize and qualify fastening methods, adhesive bonding, composite layups, surface treatments, and machining processes for space applications.
* Support material and process qualifications, maintain internal specifications, and ensure compliance with industry standards.
* Investigate production anomalies, conduct root cause analysis, and implement CAPA.
* Engage with suppliers to ensure robustness of externally provided materials and processes.
