We’re hiring research engineers across model training, ML infrastructure, full-stack product engineering, and customer deployment. Your focus will depend on your strengths and the problems you take ownership of.\nYou might implement training algorithms and recipes; build distributed training and inference systems; develop data pipelines and evaluations; create interfaces for running experiments and improving models; or work directly with customers to integrate their data and workflows and deploy specialized models. Across these areas, you’ll work closely with researchers and engineers and turn successful approaches into reliable, reusable capabilities.\nRequirements\nTypically 3+ years of software or ML engineering experience, including relevant academic or industry research (preferred), or equivalent demonstrated work.\nOwned a substantial system from implementation through deployment and ongoing operation.\nRole-specific requirements:\nModel training: typically 1+ year training language or multimodal models; hands-on PyTorch or JAX; experience building distributed training pipelines.\nML infrastructure: built and operated distributed GPU workloads, including job scheduling, containers, checkpointing, failure recovery, and profiling training or inference performance.\nCustomer deployment: owned a production integration involving customer data, APIs, and cloud infrastructure; debugged systems in customer environments and worked directly with technical customers.","description_format":"text","description_chars":1548,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-14T22:51:21Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":30,"reasons":["conf:3","win:early"],"computed_at":"2026-10-15T05:46:00Z"},"pay":{"stated_usd_annual":250000,"is_top_pay":true},"html_url":"https://alion.io/job/trainloop-research-engineer","json_url":"https://alion.io/job/trainloop-research-engineer.json","meta":{"generated_at":"2026-10-15T15:39:38Z","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":23943,"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":3779358},"rest":"https://alion.io/mcp/rest/get_company?id=3779358"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ftrainloop-research-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%2Ftrainloop-research-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%2Ftrainloop-research-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/trainloop-research-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ftrainloop-research-engineer"}]}
