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.\nSOFTWARE ENGINEER, SECURITY\nYou form hypotheses about why data is helping or misleading the model, build the systems to test them, run ablations, and read the rollouts to find the bug, shortcut or mismatch behind a result. Every flaw you catch, or miss, shows up in what the next Grok models learn.\nRESPONSIBILITIES:\nBuild AI augmented code review to get involved in important systems at the right time\n\nBuild a least-privilege and JIT system for cloud access that enables engineers and enforces least privileges\n\nImplement a safe environment for agents to engage with code\n\nImplement a framework for securely handling agent manipulation of user systems (e.g., MCP tool calls and command execution)\n\nImplement a paved road for preventing inappropriate data from being logged\n\nBASIC QUALIFICATIONS:\nExperience building or scaling secure systems in fast-moving environments\n\nPREFERRED SKILLS AND EXPERIENCE:\nA strong software engineer first, with security as your superpower\n\nThink like both a builder and an attacker: you anticipate vulnerabilities before they become issues\n\nCare about developer experience, building solutions that are secure and frictionless\n\nComfortable moving quickly, owning problems end to end, and iterating with limited guidance\n\nStrong opinions on secure defaults, but can balance pragmatism with rigor\n\nEnjoy working on small, high-talent teams where impact is magnified\n\nMotivated by protecting developers and users, and you see security as an enabler\n\nADDITIONAL REQUIREMENTS:\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$140,000 - $225,000 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":3105,"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","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":1,"expected_fill_days":89,"reasons":["conf:2","win:early","comp:brand"],"computed_at":"2026-11-11T03:27:49Z"},"pay":{"stated_usd_annual":225000,"is_top_pay":true},"html_url":"https://alion.io/job/cursor-software-engineer-security-2","json_url":"https://alion.io/job/cursor-software-engineer-security-2.json","meta":{"generated_at":"2026-11-11T03:27:49Z","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":2793,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-12T00:00:00Z"}},"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-software-engineer-security-2"},{"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-software-engineer-security-2"},{"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-software-engineer-security-2"},{"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-security-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcursor-software-engineer-security-2"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4008600}},{"tool":"search_jobs","arguments":{"company":"cursor.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4008600},"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.
