Today, SpaceX is actively developing the technologies to make this possible, with the ultimate goal of making life multiplanetary and expanding consciousness to the stars.\nSpaceXSI is building Super Intelligence to help humanity understand the universe. Our teams are building the full Super Intelligence stack: from our Colossus supercomputers, to Grok models, to our suite of applications, including Grok Bot, Grok Build, Grok Imagine, Grok Voice, and X. We're creating a powerful flywheel where more compute trains better models, better models power more useful products, and what we learn from people using those products shapes what we build next.\nAbout the Role\nAs a Software Engineer on Compute Infra at SpaceXAI, you'll build the sandbox infrastructure to give every agent their own VM. These VMs power coding agents, Grok Bot, reinforcement learning, and more. We operate one of the largest set of sandbox clusters in the world, at millions of CPU cores, across third- and first-party datacenters. You’ll own developing a cloud for agents, including the virtualization layer (Firecracker and Cloud Hypervisor microVMs), control plane scaling, and the networking/connectivity layer on top.\nResponsibilities\nRearchitecting the control plane / scheduler to support 1 million concurrent VMs per cluster.\n\nBuilding a ublk block device that can dedupe, lazy load, and efficiently snapshot VM data.\n\nDesigning an egress proxy and network isolation to securely filter, monitor, and route agent traffic.\n\nDesigning resilient systems that can operate across a mixture of cloud and on-premise datacenters.\n\nBasic Qualifications\nBachelor's degree in computer science, engineering, math, or scientific discipline; OR 2+ years of professional experience building software in lieu of a degree\n\nPreferred Skills and Experience\nYou have deep experience with building compute orchestration (e.g. Kubernetes, Mesos).\n\nYou have built and operated large fleets of VMs / isolated sandboxes.\n\nYou have experience with the Linux kernel and virtualization technologies.\n\nYou enjoy thinking about infrastructure primitives that future agents will require.","description_format":"text","description_chars":2288,"description_truncated":false,"requirements":{"experience_years_min":2,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Agents","Code Intelligence","AI Development Tools"],"lifecycle":[{"event":"open","at":"2026-10-22T20:35:32Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":1,"expected_fill_days":89,"reasons":["conf:2","velocity","win:early","comp:junior,brand"],"computed_at":"2026-10-24T06:02:35Z"},"pay":null,"html_url":"https://alion.io/job/cursor-software-engineer-compute-infra","json_url":"https://alion.io/job/cursor-software-engineer-compute-infra.json","meta":{"generated_at":"2026-10-24T15:39:22Z","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":22512,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-25T00:00:00Z"}},"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-compute-infra"},{"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-compute-infra"},{"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-compute-infra"},{"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-compute-infra\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcursor-software-engineer-compute-infra"}]}
