Our team combines multiphysics models, machine learning and experimental data to understand systems such as plasma reactors and high-temperature metallurgical processes.\nWe can build sophisticated models and fast surrogates. Now we want to turn that capability into robust software that can be used beyond our own research environment.\nWHAT WE ARE BUILDING\nGREEN14 started five years ago with a mission to develop emission-free production of critical raw materials using hydrogen plasma.\nToday, we operate a full-scale plasma reactor in Stockholm. Alongside it, we have built capabilities in multiphysics simulation, AI and surrogate modelling.\nOur ambition is to connect experiments, physics, simulation, surrogate models and optimization into a continuous learning process.\nBut a great model sitting in a research notebook is not a product. Models need data and pipelines. Experiments need to be reproducible. Software needs APIs. Models need to be tested and versioned. Computation needs to be fast and reliable.\nThat is where you come in.\nYOUR ROLE\nYou will build the software and computational infrastructure connecting our physics, AI and experimental data.\nYou will work directly with scientists and engineers developing our models and turn research code into software other engineers can reliably use.\nA typical problem might start with JAX code developed by a researcher. Your job is to ask:\nHow do we make this reliable, testable, reproducible, fast and usable by someone who did not write it?\nYou will have substantial ownership over the technical foundations of our simulation platform.\nWHAT YOU WILL DO\nBuild backend architectures connecting sensor data, physics models, ML models and simulation workflows.\n\nTurn JAX-based research code into maintainable, production-ready software.\n\nBuild pipelines connecting experimental data, simulation, surrogates and optimization.\n\nDevelop infrastructure for model training, evaluation and reproducibility.\n\nBuild APIs, packages and repositories for long-term production use.\n\nEstablish testing, CI/CD, versioning and monitoring for scientific software.\n\nIdentify computational bottlenecks and improve performance.\n\nContribute to deployment and cloud infrastructure as our products mature.\n\nWHO YOU ARE\nYou have experience taking technically complex software from prototype to something other people can reliably use.\nYou might come from software engineering, ML engineering, scientific computing or data engineering.\nWe are particularly interested in experience with:\nPython and modern software engineering.\n\nJAX or other numerical and ML frameworks.\n\nBackend architectures and APIs.\n\nData pipelines and databases.\n\nML infrastructure and MLOps.\n\nTesting, CI/CD and reproducible workflows.\n\nComputationally intensive workloads.\n\nExperience with Docker, cloud infrastructure, Kubernetes, GPU computing, FastAPI or ML tooling is useful. Experience with JAX, scientific computing or simulation software is particularly relevant.\nWe do not expect you to tick every box.\nTHE KIND OF PERSON WE ARE LOOKING FOR\nYou do not need to be a plasma physicist.\nWhat matters is that you enjoy working at the boundary between scientific computing, machine learning and real-world software engineering.\nYou like understanding what researchers are trying to achieve, but your instinct is to turn clever prototypes into systems other people can depend on.\nYou care about architecture, performance and maintainability, but you also write code.\nYou should also be curious about the physical world behind the software. Our code represents real plasma, particles, materials and experiments.\nWHY GREEN14\nMany software engineers working in simulation never see the physical system their code represents.\nHere, the reactor is downstairs.\nOur engineers run experiments. Sensors generate data. Our simulation team compares results with models. The models improve. You build the infrastructure that makes that loop faster and more reliable.\nOur ambition is broader than one reactor. We want to help engineers understand, optimize and scale complex high-temperature processes across industries.\nHOW WE WORK\nYou will join a team of serious engineers and scientists who care about getting things right.\nWe are international, curious and direct. We challenge each other's thinking and change our minds when the data tells us to.\nThere is very little hierarchy. Good ideas matter more than titles.\nWe are ambitious, but low on ego. We work hard, flexibly, and value having a life outside work.\nTHE PRACTICAL STUFF\nCompensation consists of salary and pension.\nWe are based at Sweden's leading technical university, close to central Stockholm and our plasma reactor.\nIf you want to turn physics, AI and experimental data into software that could change how industrial processes are developed and optimized, we would like to hear from you.\nThe position will remain open until we find the right person.","description_format":"text","description_chars":5092,"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":["Continuous learning"],"hiring_locations":[{"name":"Sweden","iso":"SE","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-04T20:27:36Z"}],"visa":[],"liveness":{"score":33,"band":"fade","label":"Fading","p_open":1,"p_active":0.602,"p_room":0.55,"age_days":27,"expected_fill_days":21,"reasons":["conf:0","win:tail"],"computed_at":"2026-10-15T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/green14-simulation-platform-ml-engineer","json_url":"https://alion.io/job/green14-simulation-platform-ml-engineer.json","meta":{"generated_at":"2026-10-15T12:28:17Z","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":19174,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-16T00:00:00Z"}},"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":2499455},"rest":"https://alion.io/mcp/rest/get_company?id=2499455"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fgreen14-simulation-platform-ml-engineer"},{"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%2Fgreen14-simulation-platform-ml-engineer"},{"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%2Fgreen14-simulation-platform-ml-engineer"},{"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/green14-simulation-platform-ml-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fgreen14-simulation-platform-ml-engineer"}]}
