You will build the shared infrastructure and post-training pipelines that help research projects scale while preserving experimental integrity.\nWhat You'll Do\nTurn research prototypes into tested, reusable data generation, training, and evaluation pipelines.\n\nBuild distributed experiment infrastructure for data loading, checkpointing, and collecting agent interactions.\n\nProfile workloads and improve GPU utilization, memory efficiency, and data throughput.\n\nDevelop tests, experiment tracking, and debugging tools while ensuring changes preserve research results.\n\nWork with researchers to translate ideas into robust, maintainable software.\n\nWhat We're Looking For\nStrong Python skills and hands-on experience with PyTorch, JAX, or a comparable machine learning framework.\n\nExperience building and debugging software for model training, inference, or large-scale data processing.\n\nUnderstanding of machine learning experiments and how data, numerical precision, and implementation choices affect results.\n\nSound software engineering practices, including testing, profiling, version control, and documentation.\n\nDistributed training or data processing experience with tools such as PyTorch distributed, DeepSpeed, or Ray is valuable.\n\nFamiliarity with model-serving, machine learning, or experiment tracking tools is a plus; reinforcement learning systems and multimodal datasets are also useful.\n\nCompensation & Benefits\nEquity is provided. Visa sponsorship is available.\nLocation\nOn-site in Zurich, Switzerland. San Francisco, California is also listed as a work location.","description_format":"text","description_chars":1698,"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":[{"name":"Switzerland","iso":"CH","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-03T20:24:15Z"}],"visa":[],"liveness":{"score":26,"band":"fade","label":"Fading","p_open":1,"p_active":0.293,"p_room":0.9,"age_days":2,"expected_fill_days":6,"reasons":["conf:0","agency","stale_co","velocity","win:mid","comp:brand"],"computed_at":"2026-10-06T05:45:30Z"},"pay":null,"html_url":"https://alion.io/job/clera-research-engineer-3","json_url":"https://alion.io/job/clera-research-engineer-3.json","meta":{"generated_at":"2026-10-07T02:22:36Z","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","counted_by":"address","units_charged":1,"used_today":3956,"day_limit":5000,"remaining_today":1044,"minute_limit":60,"resets_at":"2026-10-08T00:00:00Z"}},"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":2706},"rest":"https://alion.io/mcp/rest/get_company?id=2706"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fclera-research-engineer-3"},{"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%2Fclera-research-engineer-3"},{"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%2Fclera-research-engineer-3"},{"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/clera-research-engineer-3\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fclera-research-engineer-3"}]}
