Software Engineer - Simulation Platform

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.

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

Shape the future of Proxima's simulation platform: imagine and build with us novel solutions for simulation tools that spark joy and reduce time-to-insight. Accelerate Stellarator R&D, at the company at its forefront: innovation in simulation tools immediately boosts Proxima Fusion's Stellarator design program.

What You Will Do

• As a platform engineer, design, develop and maintain next-generation software solutions for stellarator simulation and design, targeted to human and agentic use: managing the full platform from automation of large-scale simulation workflows, to cloud-based data storage, to applications that foster cross-domain collaboration
• As a forward-deployed engineer, work together with our researchers to apply our tools to specific use cases: guide users to make the most of the available simulation tooling and proactively co-develop applications that unblock their R&D program

Who You Are

• A talented software practitioner with a user-first mindset, interested in tackling a diverse mix of challenges: from the optimization of scientific computing workflows to building cloud- and web-based systems for data management
• Proficient in Python; familiarity with Pydantic, JAX, full-stack web development (React, TypeScript, FastAPI), cloud services, and data management systems is desirable but not required
• You enjoy staying up to date with current software development best practices, e.g. agentic development or modern data pipelines and scheduling solutions
• You enjoy diving into new problems with a continuous learning attitude
