The first step in our journey is to build the best tool for professional programmers, using a combination of inventive research, design, and engineering. Our organization is very flat, and our team is small and talent dense. We particularly like people who are truth-seeking, passionate, and creative. We enjoy spirited debate, crazy ideas, and shipping code.\nAbout the role\nThe ML Infrastructure team builds large-scale compute, storage, and software infrastructure to support Cursor’s work building the world’s best agentic coding model. We’re looking for strong engineers who are interested in building high-performance infrastructure and the software to support it. This role works closely with ML researchers and engineers to enable their work through improvements to our training framework, systems reliability/performance, and developer experience.\nWhat you’ll do\nCollaborate with ML researchers to improve the throughput and reliability of training\n\nWork with OEMs, cloud service providers, and others to plan and build cutting-edge GPU infrastructure\n\nImprove the density and scalability of compute environments to enable increasingly large RL workloads\n\nCreate software and systems to automate building, monitoring, and running GPU clusters\n\nBuild workload scheduling and data movement systems to support Cursor’s growing training footprint\n\nYou may be a fit if\nA strong background in systems and infrastructure-focused software engineering, particularly in Python, Typescript, Rust, and Golang\n\nExperience with distributed storage and networking infrastructure, particularly on Linux systems across cloud and bare metal environments\n\nExposure to large-scale systems and their unique challenges, ideally across thousands of nodes with significant resource footprints.\n\nProduction use of infrastructure-as-code and configuration management, across hosts and Kubernetes\n\nNice to have\nOperational exposure to Nvidia GPUs with Infiniband or RoCE, particularly with Blackwell and Hopper-class hardware\n\nExposure to Ray, Slurm, or other common compute and runtime schedulers","description_format":"text","description_chars":2113,"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":["AI Agents","Code Intelligence","AI Development Tools"],"lifecycle":[{"event":"open","at":"2026-01-27T22:51:35Z"}],"visa":[],"liveness":{"score":8,"band":"cold","label":"Long shot","p_open":1,"p_active":0.3,"p_room":0.28,"age_days":262,"expected_fill_days":81,"reasons":["conf:2","velocity","ghost","win:tail","crowd:brand"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/cursor-software-engineer-ml-infrastructure","json_url":"https://alion.io/job/cursor-software-engineer-ml-infrastructure.json","meta":{"generated_at":"2026-10-18T06:43:23Z","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":9998,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"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":16873},"rest":"https://alion.io/mcp/rest/get_company?id=16873"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcursor-software-engineer-ml-infrastructure"},{"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%2Fcursor-software-engineer-ml-infrastructure"},{"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%2Fcursor-software-engineer-ml-infrastructure"},{"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/cursor-software-engineer-ml-infrastructure\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcursor-software-engineer-ml-infrastructure"}]}
