Job Summary
Summary
MuRay Tech is a deeptech spinout from DESY Hamburg. Were hiring an LPA Design Engineer to own the working point design of our high-energy high-charge laser-plasma accelerator. Youll optimise plasma density profiles through PIC simulation build a physics-informed surrogate model as a digital twin of the accelerator and run the tolerance studies that make the design hold up in real hardware. Direct ownership of the beam that powers our Active Muon Imaging system.
The role
As LPA Design Engineer youll own the working point design of MuRays high-energy high-charge laser-plasma accelerator. Concretely you will:
- Design density profiles that maximise high energy and minimise low energy charge. Real hardware sets the limits.
- Extend the simulation chain from reduced-dimensionality models to full 3D. This captures effects a symmetric model misses.
- Build an efficient optimisation loop that respects the cost of each simulation. Map the Pareto front between muon yield and radiation dose.
- Develop a surrogate model as a digital twin of the LPA. Implement physics-informed architectures.
- Run tolerance and jitter studies to test robustness of the chosen working point against real-world variation.
What youll bring
- Physics background: deep understanding of laser-plasma acceleration injection dephasing depletion external and self-guiding physics.
- PIC simulation expertise: hands-on with FBPIC WarpX or a comparable code.
- Optimisation track record: applied use of Bayesian optimisation or similar methods for multi-objective search.
- Machine learning skills: building surrogate models from simulation data. Physics-informed AI that encodes known physics into the network architecture.
- Statistical judgment: for tolerance work you characterise a robust basin not just find a peak.
- Software and HPC fluency: Python reproducible simulation pipelines cluster-scale sweeps.
How we work
- Skunkworks approach: We work in small teams with full ownership. We keep it simple stupid.
- Move fast: a shiny prototype means we spent too long on it. We build to learn. We polish later.
- Disagree together commit together: we debate and challenge regardless of title. Then we deliver the decision as one team. We win as a team. We pivot as a team.
- Courage: we always make the call. A mistake isnt a failure: its proof were improving. Either way we own the outcome.
- Honesty and transparency: we share whats really happening good or bad. That lets everyone make the right call. We stay open. We stay honest.
What we offer
- Impact: your working point isnt a paper result. It becomes the beam that powers the first Active Muon Imaging system scanning rocket engines turbine components and shipping containers.
- Pace: rapid real-life validation of your plasma profile designs. Within a few years your working point is running real scans.
- Infrastructure: you have access to LUMI. You also have access to an H200 GPU cluster in Hamburg.
- Network: development and business collaborators include DESY German Space Agency (DLR) Siemens Energy Marvel Fusion Caelora.
- Ownership: an equity plan gives you a meaningful stake in the company.
- Compensation: a salary that reflects your contribution to MuRays growth.
- Relocation: we support your move. If youre relocating from outside the EU we help with the paperwork.

About us
MuRay builds compact laser-plasma accelerators that generate a controlled muon beam. Muon scans today are passive and take days. Active Muon Imaging produces the same scan in seconds at higher resolution. We work with partners in aerospace defence and energy today. Next: security customs and medical imaging.
