Job Summary
Summary
MuRay Tech is a deeptech spinout from DESY Hamburg. Were hiring a Muon Tomography Engineer to build the algorithms that turn raw track data into 3D density reconstructions for our Active Muon Imaging system. Youll take reconstruction from POCA and ASR through to likelihood-optimization methods fuse in optical priors and solve the statistics of high-flux track pile-up. Direct ownership of the tool a customers pass/fail decision runs on.
The role
As Muon Tomography Engineer youll own how raw track data becomes a 3D density reconstruction. That spans algorithm development multi-modal data fusion and the statistical methods that make it work at scale. Concretely you will:
- Implement density reconstruction methods taking inspiration from likelihood-optimization-based methods. Package the result as a standalone tool.
- Explore adaptive reconstruction grids to reduce memory requirements and increase reconstruction speed.
- Optimise reconstructionalgorithms to leverage the muon beams narrow energy bandwidth using spectral width as a per-track error estimate.
- Explore fusing optical images of the scan volume and DUT geometry into the reconstruction as constraints that further limit the solution space.
- Develop statistical methods to resolve track pile-up at high muon flux where one-track-at-a-time assumptions break down.
What youll bring
- Tomographic reconstruction expertise. Youve implemented POCA ASR or comparable scattering-tomography algorithms. You move to likelihood optimization when point-based methods run out of accuracy.
- Numerical methods for performance. Youve built adaptive or multi-resolution grids before. Youve traded resolution against memory and speed to do it.
- Uncertainty modeling. You turn a beams energy spectrum into a per-track error weight not a single global constant.
- Multi-modal data fusion. Youve combined tomographic data with an external prior before like an optical image or object geometry. Youve used it as a hard constraint on the solution not just a reference.
- High-flux track statistics. Youve solved pile-up or hit-ambiguity problems in tracking detectors before where more than one particle can be in the detector at once.
- Production software engineering. You take a reconstruction method from research code to a maintained standalone tool with a fixed input/output format.
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: you own the tool that turns raw tracks into density maps. That output is what a customer bases a decision on: pass or fail repair or replace.
- Pace:commercial scanning services launch within a year. Your reconstruction tool makes that possible from day one.
- Data:MuRay has on-demand time at multi-GeV beamlines including DESYs PRIMA. That gives you dense controlled-source track data to develop and validate against.
- 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.
