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.\nSR. SOFTWARE ENGINEER, ML PLATFORM\nAs a Software Engineer on ML Platform at SpaceXSI, you'll build the infrastructure that turns real product usage into better models, and keeps research moving fast on large GPU fleets. ML Platform is organized into four teams. Depending on your background, you may join any of them. We're looking for strong distributed-systems and infrastructure engineers who want to sit next to research and ship platform primitives that move the product.\nRESPONSIBILITIES:\nDesign, build, and operate core platform systems used daily by ML researchers and product engineers\n\nPartner closely with research to turn recurring pain into durable infrastructure\n\nOwn reliability, performance, and developer experience for the systems in your lane\n\nShip iteratively in a flat, high-ownership environment. Measure impact, then raise the bar\n\nBASIC QUALIFICATIONS:\nBachelor's, Master's, or PhD in computer science, machine learning, or another quantitative discipline; OR equivalent work experience\n\n5+ years of industry experience working with production distributed systems (e.g., infrastructure, ingestion, data pipelines, or scheduling/orchestration, etc.)\n\nPREFERRED SKILLS AND EXPERIENCE:\nExperience owning production distributed systems at meaningful scale (ingestion, data pipelines, scheduling/orchestration, or similar)\n\nExperience partnering and building platforms for ML researchers and product engineers\n\nThrive where ownership is high and the feedback loop is short\n\nTelemetry: event ingestion, product analytics pipelines, OpenTelemetry / tracing, reliable data APIs\n\nProduct Data Platform: data frameworks, Spark / Flink / Ray, ML dataset and training-data infrastructure\n\nObservability: experiment / run monitoring, debug and eval tooling, agent-friendly observability UX\n\nML DevX and Systems: GPU / cluster scheduling, job queues, node health, research compute developer experience\n\nADDITIONAL REQUIREMENTS:\nWe're in-person with cozy offices in North Beach, San Francisco, Palo Alto, and Manhattan, New York, complete with well-stocked libraries\n\nIf there appears to be a fit, we'll reach out to schedule 2-3 short technicals. After, we'll schedule an onsite in our office, where you'll work on a small project, discuss ideas, and meet the team\n\nCOMPENSATION AND BENEFITS:\nThe annual compensation range for this role is listed below.\nAnnual Salary:\n$180,000 - $330,000 USD\nYour actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, and experience.\nBase salary is just one part of our total rewards package at SpaceXSI, which also includes equity, comprehensive medical, vision, and dental coverage, access to a 401(k) retirement plan, short & long-term disability insurance, life insurance, and various other discounts and perks.","description_format":"text","description_chars":3677,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Equity","Life insurance","Retirement plans"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Agents","Code Intelligence","AI Development Tools"],"lifecycle":[{"event":"open","at":"2026-11-10T08:42:34Z"}],"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":89,"reasons":["conf:1","win:early","comp:brand"],"computed_at":"2026-11-10T09:54:34Z"},"pay":{"stated_usd_annual":330000,"is_top_pay":true},"html_url":"https://alion.io/job/cursor-sr-software-engineer-ml-platform","json_url":"https://alion.io/job/cursor-sr-software-engineer-ml-platform.json","meta":{"generated_at":"2026-11-10T09:54:34Z","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":22992,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-11T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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-sr-software-engineer-ml-platform"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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-sr-software-engineer-ml-platform"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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-sr-software-engineer-ml-platform"},{"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-sr-software-engineer-ml-platform\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcursor-sr-software-engineer-ml-platform"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4008596}},{"tool":"search_jobs","arguments":{"company":"cursor.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4008596},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
