We're hiring an LPA Design Engineer to own the working point design of our high-energy, high-charge laser-plasma accelerator. You'll 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\nAs LPA Design Engineer, you'll own the working point design of MuRay's 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.\nExtend the simulation chain from reduced-dimensionality models to full 3D. This captures effects a symmetric model misses.\nBuild an efficient optimisation loop that respects the cost of each simulation. Map the Pareto front between muon yield and radiation dose.\nDevelop a surrogate model as a digital twin of the LPA. Implement physics-informed architectures.\nRun tolerance and jitter studies to test robustness of the chosen working point against real-world variation.\nWhat you'll bring\nPhysics background: deep understanding of laser-plasma acceleration, injection, dephasing, depletion, external and self-guiding physics.\nPIC simulation expertise: hands-on with FBPIC, WarpX, or a comparable code.\nOptimisation track record: applied use of Bayesian optimisation or similar methods for multi-objective search.\nMachine learning skills: building surrogate models from simulation data. Physics-informed AI that encodes known physics into the network architecture.\nStatistical judgment: for tolerance work, you characterise a robust basin, not just find a peak.\nSoftware and HPC fluency: Python, reproducible simulation pipelines, cluster-scale sweeps.\nHow we work\nSkunkworks approach: We work in small teams with full ownership. We keep it simple, stupid.\nMove fast: a shiny prototype means we spent too long on it. We build to learn. We polish later.\nDisagree 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.\nCourage: we always make the call. A mistake isn't a failure: it's proof we're improving. Either way, we own the outcome.\nHonesty and transparency: we share what's really happening, good or bad. That lets everyone make the right call. We stay open. We stay honest.\nWhat we offer\nImpact: your working point isn't a paper result. It becomes the beam that powers the first Active Muon Imaging system, scanning rocket engines, turbine components, and shipping containers.\nPace: rapid real-life validation of your plasma profile designs. Within a few years, your working point is running real scans.\nInfrastructure: you have access to LUMI. You also have access to an H200 GPU cluster in Hamburg.\nNetwork: research collaborators include DESY, DLR, CERN, and Imperial College London. Commercial partners include Siemens Energy, Airbus, Caelora, and ZAL.\nOwnership: an equity plan gives you a meaningful stake in the company.\nCompensation: a salary that reflects your contribution to MuRay's growth.\nRelocation: we support your move. If you're relocating from outside the EU, we help with the paperwork.\nContact\nFor any additional questions, feel free to reach out to  or apply directly through our application form!We are looking forward to hearing from you.","description_format":"text","description_chars":3527,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":["3D Printers & Additive Manufacturing"],"lifecycle":[{"event":"open","at":"2026-10-07T14:36:36Z"}],"visa":[],"liveness":{"score":22,"band":"cold","label":"Long shot","p_open":1,"p_active":0.488,"p_room":0.45,"age_days":33,"expected_fill_days":20,"reasons":["conf:8","win:tail"],"computed_at":"2026-10-13T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/muray-lpa-design-engineer-mfd","json_url":"https://alion.io/job/muray-lpa-design-engineer-mfd.json","meta":{"generated_at":"2026-10-14T00:49:58Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":1170,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-15T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":3875867},"rest":"https://alion.io/mcp/rest/get_company?id=3875867"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmuray-lpa-design-engineer-mfd"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fmuray-lpa-design-engineer-mfd"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fmuray-lpa-design-engineer-mfd"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/muray-lpa-design-engineer-mfd\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmuray-lpa-design-engineer-mfd"}]}
