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.The role\nAs 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.\nSet the strategy for density reconstruction from muon detector hit data. Build the simulation chain and training infrastructure to develop and validate the models.\nDevelop autonomous LPA operation and control. Build systems that optimise their own working point.\nBuild AI/ML at MuRay from the ground up, across the company and the product.\nWhat you'll bring\nA track record of building ML teams. You've grown an ML team from a small base before, at a startup or research lab. You're ready to be hands-on again before the team here exists.\nDepth 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.\nML 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.\nEnd-to-end pipeline experience. You've taken physics simulation output through to a trained, deployed model. You've handled the sim-to-real gap.\nPhysics fluency and pragmatic engineering judgment. Comfort at the ML/physics interface. A bias toward infrastructure that fits a small team, not a hyperscaler.\nCommunication people trust. You translate cleanly between ML, physics, and business audiences. You prioritise validated, defensible results over impressive demos.\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: you'll shape MuRay's technical direction. You'll help build the next generation of non-destructive testing methods.\nAutonomy: this is a founding role. You build the team, infrastructure, and tooling from the ground up.\nNetwork: research collaborators include DESY, DLR, CERN, and Imperial College London. Commercial partners include Siemens Energy, Airbus, Caelora, and ZAL.\nInfrastructure: you have access to LUMI. You also have access to an H200 GPU cluster in Hamburg.\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":3685,"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":36,"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-founding-aiml-engineer-mfd","json_url":"https://alion.io/job/muray-founding-aiml-engineer-mfd.json","meta":{"generated_at":"2026-10-14T04:50:42Z","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":6802,"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-founding-aiml-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-founding-aiml-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-founding-aiml-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-founding-aiml-engineer-mfd\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmuray-founding-aiml-engineer-mfd"}]}
