SWISSto12 is one of the fastest-growing aerospace companies in the world, evolving from its pioneering use of 3D printing technologies for high-performance Radio Frequency (RF) products and applications to the recent announcement of the manufacturing of entire geostationary telecommunications satellites, called HummingSat, which define a new category in space.
HummingSat is the world's first commercial SmallSat GEO telecommunications satellite developed in collaboration with the European Space Agency (ESA). Its exceptionally compact size combined with high-performance telecommunications payloads allows telecommunications operators to deploy a cost-effective, compact, and agile asset without sacrificing performance or security. HummingSat was 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 subsystems for satellite communication and remote sensing applications. The company's patented 3D printing technologies and associated product designs are unique in providing lightweight, compact, high-performance, and competitive RF products.
This position is a unique opportunity to play a key role in the machining and finishing of complex and high-precision components for RF systems used in space applications. As a machining operator, you will work on 5-axis CNC milling, turning, and EDM equipment to manufacture unique parts and small series from metal additive manufacturing and conventional raw materials. You will be part of a multidisciplinary production team collaborating closely with manufacturing engineers and process managers to ensure that every part meets demanding aerospace standards for precision, surface quality, and reliability.

Polymechanical Technician

Job Responsibilities

Machining Operations:

• Program, set up, and operate CNC milling.
• Perform wire EDM cutting and finishing of metal components.
• Machine and rework 3D printed metal parts and conventional blanks to final geometry.
• Fabricate or adapt custom jigs and fixtures if necessary.

Quality & Inspection:

• Perform self-inspection using conventional metrology tools (micrometers, calipers, gauges) and 3D scanning systems.
• Interpret engineering drawings (ISO GPS / GD&T) and verify part compliance.
• Record inspection data and support traceability requirements for space-quality material.

Collaboration & Improvement:

• Interact daily with machining and process engineering teams to optimize setups and machining strategies.
• Propose improvements to programs, tools, and methods to reduce cycle times and improve precision.
• Follow production plans and support other operators if necessary.

Maintainability & Safety:

• Execute daily and weekly maintenance tasks according to the Total Productive Maintenance (TPM) plan defined by the Process & Manufacturing Engineering department.
• Report anomalies, recurring failures, or improvement ideas to maintain machine reliability.
• Apply all relevant EHS and cleanroom regulations related to machining and metal dust management.

Job Requirements

• CFC in Polymechanical Technician / Precision Mechanic or equivalent qualification.
• 3 to 5 years of experience in CNC and/or EDM machining in a precision manufacturing environment.
• Strong ability to read and interpret complex 2D and 3D drawings (ISO GPS).
• Experience in programming and probing cycles (e.g., Heidenhain, Siemens, Fanuc).
• Knowledge of SolidWorks and Alphacam (or equivalent CAM software) is an asset.
• Rigor, autonomy, and attention to detail.
• Team spirit and comfortable in a multidisciplinary and multicultural environment.
• French required; English minimum level B1.
