Our mission is to Underwrite superintelligence. We exist because risk, not capability, is becoming the binding constraint on AI being useful. History offers lessons for how to build confidence in new technology; electricity burned down houses until insurers funded Underwriters Laboratories (UL) to certify products against their standards. Today, the UL mark is a trustmark on every light bulb in America. We’re building that for AI.\nAIUC-1, our standard for agent security, serves frontier builders like Cursor, Lovable, ElevenLabs, and Harvey. We've raised $55m from Ribbit, First Harmonic and Nat Friedman to audit frontier AI. Our team comes from METR, Anthropic, McKinsey, and OpenAI. Come join us.\nThe Role\nAI agents now handle sensitive data and run real infrastructure. Their biggest risks, from prompt injection and credential sprawl to tool misuse and MCP and A2A attacks, still have no established defenses.\nAIUC-1 is the standard Fortune 500 CISOs use to decide which AI agents they can trust. That only works if we’re the most secure company in the room.\nYou’ll be our first security hire, joining as we open our product to the world, while our own agents test other companies’ agents. You’ll own security end to end across our product, evaluation platform, and internal systems, and work directly with the founders. You’ll take on agent security problems nobody has solved, prove the answers on our own systems, and watch them become the playbook other companies follow.\nFrom there, the ceiling is yours: become the security leader who advises our consortium of 300+ CISOs, helps shape AIUC-1’s security requirements, and defines what agent security means in practice.\nThis role is hard. You’ll say no often, including to the founders, and hold the line when it’s unpopular. The best way to make that work is to make the secure path the fast path. When you’re doing it well, no one talks about security.\nIn this role, you will:\nMake sure our product is secure as it reaches more and more enterprise customers\n\nBuild the secure foundation for running agents: sandboxing, agent credential access, and core development\n\nOwn security across the company: network, vendors, access, data, and customer security reviews\n\nGet ahead of the risks we don’t have yet, as new products and attack classes emerge\n\nRespond to incidents fast, and fix problems before they become incidents\n\nFeed what you learn back into AIUC-1, and share it with our CISO consortium through sessions and published work\n\nWhat we're looking for\nYou’ve likely done this before: as the founding security hire at a technical or regulated-industry company, building the program from zero; or as a core engineer at a security company, where getting security right was the product.\nEngineer first: you’ve built production systems, can clear our full engineering bar, and want to start hands-on before growing into leading security\n\nCloud and infrastructure security: you’ve secured least-privilege IAM, SSO, clean dev/prod separation, KMS and secrets management, plus secure databases, user management, and identity systems\n\nAgent builder: you’ve built an agent harness and know how to contain one, through sandboxing, tool permissions, credential isolation, and data-leak controls\n\nHolds the line, keeps people on side: you own outcomes end to end and can say no without being pushed around or burning bridges\n\nReady when things break: you’ve built detection, logging, and incident response, and secured the corporate surface (SSO, devices, SaaS)\n\nSecurity as code: you review infrastructure changes in Terraform and automate controls so engineers move faster, not slower\n\nNice to Haves\nYou’ve turned security research into production engineering (e.g. reproducing new attacks on agents and shipping the defenses)\n\nDeep architecture experience across distributed systems, ML pipelines, or large-scale platforms\n\nYou’d enjoy learning from enterprise security teams, from our CISO consortium to customers, how agents are changing their environments\n\nOur Values\nWe are in the business of building trust. We take our values seriously and treat them as commitments to each other, held to the same bar as the ones we make to customers.\nStrong back: high standards, keep our promises, work hard.\nFast feet: experiment, cut scope, take delight in pace.\nEyes up: wrestle with the mission, and let where AI is heading shape our strategy, our teams and our day-to-day work.\nOpen heart: say the scary thing, create connection, make room for emotions.\nUnderwriting superintelligence is our life's work. If you want it to be yours, apply now.\nCompensation & Perks\nCompetitive annual salary\n\nEquity (significant part of total compensation)\n\nHealth, dental and vision insurance for you and your dependents\n\nVisa sponsorship and relocation stipend to bring you to SF, if needed\n\nDaily lunch, dinner & snacks","description_format":"text","description_chars":4927,"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","Vision insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":["AI Agents","AI Governance & Compliance","InsurTech"],"lifecycle":[{"event":"open","at":"2026-10-17T03:15:16Z"}],"visa":[],"liveness":{"score":60,"band":"ok","label":"Likely open","p_open":1,"p_active":0.602,"p_room":1,"age_days":0,"expected_fill_days":33,"reasons":["conf:2","stale_co","win:early"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":400000,"is_top_pay":true},"html_url":"https://alion.io/job/aiuc-founding-security-engineer","json_url":"https://alion.io/job/aiuc-founding-security-engineer.json","meta":{"generated_at":"2026-10-17T10:20:56Z","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":13489,"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":669190},"rest":"https://alion.io/mcp/rest/get_company?id=669190"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Faiuc-founding-security-engineer"},{"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%2Faiuc-founding-security-engineer"},{"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%2Faiuc-founding-security-engineer"},{"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/aiuc-founding-security-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Faiuc-founding-security-engineer"}]}
