We train frontier models that learn the underlying foundations of biochemical structure and interaction, so scientists can move faster and pursue targets that other methods cannot reach.\nAI is reinventing life sciences the same way it reinvented software engineering, and Chai is at the forefront of this shift. Leading pharmaceutical companies like Eli Lilly, Pfizer, and Novartis are adopting our platform to power their drug discovery programs.\nWe value diverse perspectives and are ready to find greatness in unexpected places.\nAbout the role\nBuild the compute infrastructure that supports Chai’s next generation of models, scientific products, and autonomous research. The capacity we bring online and how well we use it determine the scale of research we can pursue and the products we can put in scientists' hands.\nBring new clusters online and build shared infrastructure for research, inference, and engineering.\n\nWork directly with researchers, engineers, and scientists to make that compute reliable and easy to use as the fleet and its demands grow.\n\nBuild the shared storage and security foundations that let people and agents use compute and data safely.\n\nOptimize model inference and serving to run more scientific work with the compute we have.\n\nAbout you\nWe look for depth in distributed systems, compute infrastructure, or performance engineering, with demonstrated ownership of substantial production systems. You can reason across layers, make sound tradeoffs around reliability and efficiency, and simplify infrastructure for the people using it.\nWe offer\nThe opportunity to work at the vanguard of AI research and frontier biology, with world-class people, on a mission that matters. We protect & promote a culture of high velocity and ownership. We compensate our team accordingly.","description_format":"text","description_chars":1869,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Foundation Models","Drug Discovery AI","AI for Science"],"lifecycle":[{"event":"open","at":"2025-11-25T19:41:16Z"},{"event":"open","at":"2026-09-25T16:47:20Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 2","filings_12m":2,"filings_prev_12m":0,"green_card_filings_12m":0,"median_offered_wage_usd":187500,"route":null,"cap_exempt":false,"checked_at":"2026-10-15T11:24:14+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":2}],"liveness":{"score":3,"band":"cold","label":"Long shot","p_open":1,"p_active":0.099,"p_room":0.28,"age_days":324,"expected_fill_days":28,"reasons":["conf:3","stale_co","velocity","ghost","win:tail","crowd:"],"computed_at":"2026-10-16T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/chai-discovery-software-engineer-platform-inference","json_url":"https://alion.io/job/chai-discovery-software-engineer-platform-inference.json","meta":{"generated_at":"2026-10-17T04:01:33Z","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":5296,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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":48006},"rest":"https://alion.io/mcp/rest/get_company?id=48006"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fchai-discovery-software-engineer-platform-inference"},{"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%2Fchai-discovery-software-engineer-platform-inference"},{"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%2Fchai-discovery-software-engineer-platform-inference"},{"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/chai-discovery-software-engineer-platform-inference\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fchai-discovery-software-engineer-platform-inference"}]}
