Senior Software Engineer (Dev Platform)

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.

Responsibilities

Build and scale the software infrastructure that enables exploration of the vast hyper-dimensional space of stellarator design; develop the core data, compute, and analysis tooling used by teams across the company; collaborate directly with fusion experts, engineers, and AI researchers to turn their workflows into robust infrastructure; shape how software is developed at Proxima - practices, quality standards, and architecture; design and develop a platform that helps simulation, optimization and stellarator design teams overcome challenges and achieve goals more efficiently; champion Cloud Infrastructure Operations; manage general cloud infrastructure (including IaaC, permission management, and cloud efficiency); support democratization of cloud computing (e.g. K8s, Ray, Dask, Docker, PEX); unify and streamline the development experience (including CI/CD, Devcontainers, and monorepos); improve observability; manage distributed computing and high-performance computing clusters for research, stellarator design and optimization; raise the bar in cross-org DevOps practices and optimize DORA metrics

Requirements

Strong foundation in computer science; understanding or hands-on experience with DevOps, CloudOps, or Platform engineering practices; familiar with the development and management of scalable cloud infrastructure; experienced in end-to-end/full-stack system design; proficient in Python and Linux; driven to solve complex problems with simple solutions; desire to contribute to clean energy

Nice to have

Experience with scalable cloud infrastructure in science, ML, or data processing-heavy use cases; experience in an environment supporting physics, engineering, or AI teams

Benefits

Work on some of the most complex tech challenges to bring abundant, safe, clean energy to the world; join and learn from an exceptional selection of accomplished and driven individuals; do your life’s best work and enjoy the journey; show that big things are possible in Europe when you assemble the best talent
