Integration Engineer, Building Services & MEP (Mechanical, Electrical and Plumbing) in München

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
• Define how all building-services systems (TGA), electrical power distribution, and cryogenic utilities integrate with the fusion machine
• Lead cross-disciplinary integration reviews and resolve routing and corridor logic
• Ensure Alpha - and later Stellaris, our first-of-a-kind power plant - has coherent, maintainable, and buildable utility systems aligned with both physics and construction constraints

WHAT YOU WILL DO

• Lead integration reviews for TGA, electrical, and cryogenic systems, ensuring constructability and clear interfaces with building and machine systems.
• Define routing strategies, utility corridors, technical spaces, penetrations, and interface envelopes across Alpha and into early Stellaris assumptions.
• Translate machine-engineering requirements (vacuum, cryo, high-power electrical, cooling) into building-ready inputs for external partners.
• Identify conflicts early using federated models, and ensure issues are resolved with disciplined configuration and documentation.
• Work closely with Structural Integration, the BIM Specialist, and the Project Manager to maintain a consistent, buildable engineering baseline.

WHO YOU ARE

• Degree in mechanical engineering, building services engineering, electrical engineering, or related field.
• Experience integrating utilities or building-services systems in complex technical or industrial environments.
• Comfortable working with incomplete or evolving requirements and shaping early engineering solutions.
• Skilled at identifying constructability and operability issues early through digital model review.
• Able to align diverse stakeholders around clear interface logic.
• INTERVIEW PROCESS
• Recruiter Interview (30-60 min)
• Technical Screening (30 min)
• Technical Panel (3x60 min)
• CEO call (30 min)

*This role sits at "Lv L 3 out of 6" of our framework, please inquire during the recruitment process for further information.

At Proxima Fusion, our mission is bold: making limitless clean energy a reality.

To get there, we need a high-performing, diverse team that brings different perspectives, challenges assumptions, and builds together with purpose.

We know that diversity of thought and experience leads to better ideas, stronger execution, and a more resilient team.

We don't look at how you identify, what you look like, who you choose to worship or what ethnicity you are.

We care about what you can bring to the table.
