About the role
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
You will join Proxima’s Enterprise AI team and be embedded into one of our workstreams.
Your home is the AI team – that’s where you get technical mentorship, work on Proxima’s AI
stack, and grow alongside other AI builders.
Your day-to-day is inside the host workstream – that’s where you find the real problems worth solving and ship the solutions that change how the team operates.Your prototypes will go into production.
Your work will directly accelerate cross-functional AI adoption across the company.
WHAT YOU WILL DO
Use Case Discovery: Shadow your host workstream, learn how the team actually works, and identify the high-leverage opportunities where AI can replace, accelerate, or augment real workflows.
Prototyping & Shipping: Build lightweight AI solutions – agents, MCP-connected tools, focused LLM workflows, and automations – in Python, with technical guidance from the Enterprise AI team.
Integration: Plug your tools into Proxima’s AI stack (Claude, Cowork, Cursor, our internal Information Hubs and MCP endpoints) and the host workstream’s own systems.
Iteration with Users: Measure impact, refine prompts and tools, and roll solutions out to the rest of the host team. AI value is created at the point of use, not in the prototype.
Knowledge Sharing: Document what you build, present at AI team reviews and company-wide Show & Tell sessions, and contribute to internal “how-to” guides so your work compounds across Proxima.
WHO YOU ARE
High-Agency Builder: You don’t wait for a manual. You see a problem, explore potential AI solutions, and start prototyping immediately.
Technically Proficient: You have a solid foundation in Python and a deep interest in the GenAI ecosystem (LLMs, agents, prompt engineering, MCP, and automation tools). You’ve built or seriously used something with Claude / ChatGPT / Cursor / Copilot or LLM APIs.
Curious About How Teams Work: You’re willing to sit in different work environments, learn their language, and find the problems worth solving. The best AI use cases come from people who understand the work.
Bias to Ship: You’d rather get a v0.1 in front of a user this week than design the perfect system for three months.
Collaborative Communicator: You enjoy working with people from different backgrounds (physicists, engineers, ops) and can translate technical workflows into clear documentation.
Startup-Ready: You thrive in high-paced environments and are excited by the “all hands on deck” culture of an early-stage fusion startup.
LOGISTICS
Hybrid or remote if outside of Munich. Minimum of 4–6 months full-time as an intern. Start: as soon as possible.
INTERVIEW PROCESS
Recruiter Interview (30-60 min)
Technical Screening (30 min)
Technical Panel (3x60 min)
CEO call (30 min)
*This role sits at "insert level" 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.
