Mechatronics & Test Engineer

As ArcSpace moves its technology from the laboratory towards flight, we are looking for a confirmed mechatronics engineer to develop, operate and improve our vacuum test infrastructure, and to strengthen the electronics and control of our hardware development.

You will:
• Prepare, run and analyse test campaigns in vacuum, from test plan to test report.
• Design, build and maintain test benches: mechanical fixtures, instrumentation, data acquisition and control software.
• Integrate and troubleshoot electromechanical assemblies, including sensors, actuators and electronics.
• Develop embedded control and monitoring functions for our processes and mechanisms.
• Work with our research partners on process diagnostics.
• Write procedures and technical documentation so that every test campaign can be reproduced by any member of the team.

REQUIREMENTS
• Master’s degree (or equivalent) in mechatronics, electrical/electronic engineering, or a closely related field.
• 3+ years of hands-on experience designing, integrating, and testing electromechanical systems (sensors, actuators, motion control, instrumentation).
• Proven experience with instrumentation and data acquisition: sensor selection/integration, signal conditioning, and DAQ systems.
• Programming for test automation and control: solid Python and/or LabVIEW experience, plus embedded C (or equivalent) for microcontrollers.
• Electronics design skills: schematic capture, PCB layout, and basic board bring-up/debugging.
• Comfortable working hands-on with electromechanical assemblies in a lab environment (assembly, troubleshooting, fixture design).
• Strong written and verbal English (C1 level); ability to produce clear test plans, procedures, and reports.

Nice to have
• Experience with vacuum systems (pumps, gauges, feedthroughs, residual gas analysis) or other controlled-environment test setups.
• Familiarity with high-voltage equipment and associated safety practices.
• Robotics or motion-control experience (e.g. ROS 2, industrial servo systems, or similar).
• PCB design tools (Altium, KiCad, or equivalent) used in a professional context.
• CAD experience for mechanical fixtures or test benches (SolidWorks preferred).
• Prior work on space hardware AIT or knowledge of ECSS standards (terrestrial electromechanical or test-equipment experience is fully acceptable).
• Exposure to process diagnostics, welding, or materials characterisation.
• Working proficiency in French.
• Eligibility to work in the EU.
• Startup mindset: proactive, adaptable, and willing to own tasks end-to-end.

Why work at ArcSpace
• A central technical role in a fast-growing European space startup.
• The chance to bring a novel in-space manufacturing technology from the lab to orbit.
• Competitive compensation.
• Close collaboration with an ambitious and driven team and its research partners.
• Company values: Fairness – Efficiency – Excellence – Teamwork.

ArcSpace is committed to building a diverse team and particularly encourages women to apply. We encourage you to apply even if you believe you do not meet all the criteria. A positive attitude, courage and willingness to learn are valued as much as hard skills.

ArcSpace develops the tools that will build and maintain the next generation of space infrastructure. In-orbit servicing, assembly and manufacturing will change how spacecraft are designed, operated and retired, and each of them depends on the ability to join, cut and assemble structures directly in orbit.

ArcSpace's core technology is an electron beam process adapted to the space environment, which uses the vacuum of space to carry out these operations. Its first applications serve in-orbit servicing, and the same technology then scales towards the assembly of large structures in orbit and on the Moon. ArcSpace is supported by ESA and CNES, works with European industrial and research partners, and is preparing its first in-orbit demonstrations.
