Today that looks like AI that reviews pull requests in GitHub, catching bugs and enforcing standards.\nGreptile reviews 5B lines of code every month for 22,000+ customers.\nProblems we’re excited about\nCoding standards can be idiosyncratic and are often poorly documented; can we build agents that learn them through osmosis like a new hire might?\n\nCan we identify for each customer what types of PR feedback they do and don’t care about in order to increase signal-to-noise ratio?\n\nSome bugs are best caught by running the code. Can we autonomously deploy feature branches and use agents to try to break the application?\n\nHow do we secure a product that processes highly sensitive code across cloud, self-hosted, and air-gapped environments?\n\nTrajectory\n22,000+ customers\n\n5B lines of code reviewed every month\n\nScaled from $0 to eight figures in ARR\n\nRaised $30M from Benchmark, Y Combinator, Paul Graham, and Initialized\n\nTeam\nWe have assembled a small, talent dense team who have scaled critical functions at companies like Stripe, Google, Figma, etc.\n\nResponsibilities\nOwn Greptile’s security posture across the product, infrastructure, and internal systems\n\nConsult on risky code changes and critical architecture decisions\n\nFix pentest findings and patch reported vulnerabilities\n\nManage our bug bounty program and coordinate vulnerability response\n\nDesign, implement, test, and deploy secure product and infrastructure improvements\n\nWork directly with engineers to make security part of how we build, rather than a final review step\n\nQualifications\nB.S. Computer Science or equivalent degree, undergraduate or higher\n\n3+ years of software engineering, DevOps, or security engineering experience\n\nExperience with JavaScript/TypeScript\n\nDeep knowledge of application, infrastructure, and cloud security\n\nExperience working on security-critical products and complex architectures\n\nStrong judgment when evaluating vulnerabilities, technical tradeoffs, and risk\n\nYou will like this role if\nYou want to work on a product that thousands of developers rely on\n\nYou want real ownership over the security of a fast-growing technical product\n\nThe chaos of high growth and things breaking is exciting to you\n\nYou like being in an office every day around other smart people who are excited about what they’re building\n\nYou love solving very hard problems.\n\nYou specifically prefer working in-person over working remote","description_format":"text","description_chars":2494,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":true},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Code Intelligence","AI Development Tools"],"lifecycle":[{"event":"open","at":"2026-08-29T23:32:20Z"}],"visa":[],"liveness":{"score":24,"band":"cold","label":"Long shot","p_open":1,"p_active":0.544,"p_room":0.45,"age_days":49,"expected_fill_days":32,"reasons":["conf:3","win:tail"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":300000,"is_top_pay":true},"html_url":"https://alion.io/job/greptile-security-engineer","json_url":"https://alion.io/job/greptile-security-engineer.json","meta":{"generated_at":"2026-10-18T06:12:59Z","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":9355,"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":48072},"rest":"https://alion.io/mcp/rest/get_company?id=48072"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fgreptile-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%2Fgreptile-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%2Fgreptile-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/greptile-security-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fgreptile-security-engineer"}]}
