WHO WE ARE

Proxima Fusion is Europe’s fastest-growing fusion company and the continent’s best-funded fusion player, as well as the first spin-out from the Max Planck Institute for Plasma Physics (IPP). Backed by over €650M and powered by a growing team across Munich, Zurich, and Oxford, we are developing the hardware and infrastructure needed to deliver the world’s first commercial stellarator fusion power plant.

Our concept advances the most mature fusion technology out there, the Wendelstein 7-X stellarator, through two next-generation machines: Alpha and Stellaris. Our work combines stellarator optimization, advanced computation, machine learning, and high-temperature superconducting magnets to unlock higher-performance designs that were previously out of reach.

Turning these designs into a functioning fusion power plant requires excellence and ownership across every discipline, from physics and engineering to software, manufacturing, law, and business functions.

WHY JOIN PROXIMA FUSION

• You will get to work on some of the most complex tech challenges to bring abundant, safe, clean energy to the world.
• You'll get to join and learn from an exceptional selection of accomplished and driven individuals.
• Do your life’s best work and enjoy the journey.
• Get to show that big things are possible in Europe when you assemble the best talent.

YOUR IMPACT

As a dedicated mechatronics specialist or mechanical engineering technician, you will be a central part of our lab team. You will help turn early mechanical and electromechanical concepts into functional prototypes. Working closely with both engineering and workshop teams, you will develop fixtures, test setups, and scalable assembly processes.

This role is ideal for a hands-on person who takes pride in precision, works independently, and enjoys collaborating with world-class engineers.

WHAT YOU WILL DO

• Build and test mechanical and electromechanical prototypes based on early-stage design concepts.
• Carry out rapid prototyping and mechanical assembly trials.
• Optimize and maintain workshop processes, tools, inventory, and calibration.
• Operate key workshop equipment such as milling machines, lathes, and test stands.
• Work closely with engineers to improve prototypes and prepare them for production.
• Perform incoming goods inspections, maintain PPE and tools, and ensure safe working practices.
• Maintain a clean, structured, and efficient lab and workshop environment.

WHO YOU ARE

• Hands-on problem solver with strong practical skills — equally effective working independently and as part of a team in a workshop environment.
• Proactive, communicative, and team-oriented — you thrive when collaborating with engineers and technicians in dynamic development environments.
• Detail-oriented and safety-conscious — with high standards for quality, precision, and safe working practices.
• Adaptable and flexible — you perform well in fast-moving, evolving technical environments with a high degree of ownership.
• Excellent German and English language skills.
• Strong technical background, such as vocational training or a technical college/university degree, with experience in machining, wiring, assembly, and test stand technology.
