# Founding AI/ML Engineer

- **Company:** MuRayTech
- **Location:** Hamburg, Germany
- **Contract:** Permanent contract
- **Skills:** Artificial Intelligence, Reinforcement Learning, Build Tools
- **Published:** November 12, 2026
- **Apply:** https://www.adzuna.de/details/5961908365

## About the Role

* Depth in ill-posed inverse problems. Physics or medical imaging reconstruction experience. The judgment to know when classical methods break down and simulation-based, probabilistic methods are the better answer.
 * ML control of real hardware. Hands-on experience with Bayesian optimization, reinforcement learning, or similar methods. Applied to a physical system with a slow or costly feedback loop.
 * End-to-end pipeline experience. You've taken physics simulation output through to a trained, deployed model. You've handled the sim-to-real gap.
 * Physics fluency and pragmatic engineering judgment. Comfort at the ML/physics interface. A bias toward infrastructure that fits a small team, not a hyperscaler.
 * Communication people trust. You translate cleanly between ML, physics, and business audiences. You prioritise validated, defensible results over impressive demos.

## Description

MuRay Tech is a deeptech spinout from DESY, Hamburg. We're hiring a Founding AI/ML Engineer to build our AI/ML function from the ground up. You'll set the technical strategy for two hard problems: density reconstruction from high-flux muon detector data, and autonomous control of our laser-plasma accelerator. As a founding hire, you'll also build the team, the simulation chain, and the training infrastructure. Broad scope. Direct ownership of a core part of the product., As Founding AI/ML Engineer, you'll own AI/ML strategy and execution across the company. That spans detector data, accelerator control, and internal tooling. You will:

 * Build the AI/ML team. Hands-on at first. Hire and structure it as scope grows.
 * Set the strategy for density reconstruction from muon detector hit data. Build the simulation chain and training infrastructure to develop and validate the models.
 * Develop autonomous LPA operation and control. Build systems that optimise their own working point.
 * Build AI/ML at MuRay from the ground up, across the company and the product., * Impact: you'll shape MuRay's technical direction. You'll help build the next generation of non-destructive testing methods.
 * Autonomy: this is a founding role. You build the team, infrastructure, and tooling from the ground up.
 * Network: development and business collaborators include DESY, German Space Agency (DLR), Siemens Energy, Marvel Fusion, Caelora.
 * Infrastructure: you have access to LUMI. You also have access to an H200 GPU cluster in Hamburg.
 * Ownership: an equity plan gives you a meaningful stake in the company.
 * Compensation: a salary that reflects your contribution to MuRay's growth.
 * Relocation: we support your move. If you're relocating from outside the EU, we help with the paperwork.
