About this role

Proxima Fusion is hiring a Senior Simulation Engineer in Munich to build numerical models for a commercial stellarator fusion power plant, suited for an experienced physicist or engineer with a strong background in software and computational methods. This role focuses on developing system-level simulation pipelines to support the development of next-generation clean energy technology.

Role Overview

The Senior Simulation Engineer joins the team in Munich to design and manage models spanning multiple domains, from microwave physics to plasma radiation. This position works closely with integrated design and engineering teams to evaluate system-level tradeoffs, execute numerical optimization, and simulate the fusion machine as a unified system.

Key Responsibilities

Identify and implement new simulators from scratch or integrate existing tools into the platform codebase.
Define and update input and output data interfaces alongside engineering teams to capture design specifications accurately.
Guarantee the verification, testing, validation, and ongoing correctness of simulation pipelines as the design evolves.
Conduct dedicated studies using the models to inform key engineering and design tradeoffs.
Build dashboards, interactive reports, and online tools to expose simulator predictions and uncertainties to the wider design team.

Requirements

Hold a Master's or PhD degree in physics, engineering, or a related discipline.
Professional background in building software simulation tools that combine numerical algorithms, geometry, and physics.
Proficiency in software engineering practices including git, CI/CD, and the PyData stack.
Experience utilizing autodifferentiation packages such as JAX or PyTorch to build production-grade tools.
Ability to select appropriate simulation methods, ranging from custom code to commercial multiphysics packages.
