Among our founding team, we have world-class competitive programmers, former founders, and leaders from companies at the cutting edge of AI including Scale AI, Palantir, Cursor, Waymo, Tesla, Lunchclub, Modal, Google DeepMind, and Nuro.\nBuilding Devin is just the first step-our hardest challenges still lie ahead. If you’re excited to solve some of the world’s biggest problems and build AI that can reason on real-world tasks, apply to join us.\nAbout the Role\nSecurity Engineers at Cognition own one of the most interesting security surfaces in the industry. Devin executes arbitrary code on behalf of users across millions of sandboxed sessions. Windsurf operates inside developer environments at scale. Both products handle highly sensitive customer code, credentials, and infrastructure access. You will help define what security looks like for AI-native developer tools and build the controls, systems, and culture that let Cognition ship fast without compromising on safety. This is a role for engineers who want to do hands-on, high-leverage security work at the edge of what is being figured out for the first time.\nWhat You'll Accomplish\nSecure the agent execution surface: Design and harden the sandboxing, isolation, and runtime controls that let Devin safely execute untrusted code and use tools across long-horizon tasks.\n\nOwn product and infrastructure security: Lead threat modeling, secure design reviews, and vulnerability management across Devin, Windsurf, and the underlying infrastructure they run on.\n\nBuild security tooling that engineers actually use: Create internal systems for secrets management, identity and access, dependency security, and detection that integrate naturally into how the team ships.\n\nLead incident response and detection: Build the detection pipeline, run incident response, and turn every event into systemic improvements.\n\nDrive customer trust: Partner with go-to-market and legal teams to support compliance and customer trust initiatives. Build the controls that customers expect from a tool deeply embedded in their engineering workflow.\n\nExceptional Candidates Have Demonstrated\nDeep security engineering: Hands-on experience across product security, infrastructure security, and detection and response.\n\nStrong software engineering fundamentals: Security at Cognition means writing real code; proficiency in Python, Rust, Go, and comfort owning complex systems codebases.\n\nCloud security expertise: Practical experience securing Kubernetes, cloud platforms (AWS, GCP, or Azure), and multi-tenant compute environments.\n\nWeb security expertise: Hands-on experience hardening complex, modern web applications.\n\nThreat modeling and adversarial thinking: You can look at a system and quickly identify how it breaks; you think like an attacker and design like a defender.\n\nIncident response: Calm, methodical, and effective under pressure; experience leading incidents end to end and driving the fixes that follow.\n\nComfort with novel problem spaces: You are excited rather than intimidated by the security challenges unique to autonomous agents and AI-native developer tools.\n\nRelevant industry experience: Prior experience at a frontier AI lab, applied AI company, or developer tools company. You know what good looks like in this category.\n\nDegree from a top-tier university: BS, MS, or equivalent in Computer Science, Mathematics, Engineering, or a related technical discipline from a highly selective program.\n\nCompensation & Benefits\nBase Salary: $260,000 - $300,000 + significant early-stage equity\n\nMedical, Dental, Vision: Fully paid for you and your dependents\n\n401(k): Company match included\n\nPerks: Private chef, cozy slippers, endless snacks, and more\nEqual Opportunity\nCognition is an equal opportunity employer. We do not discriminate on the basis of race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, veteran status, or any other protected characteristic under applicable law. We are committed to providing reasonable accommodations for candidates with disabilities throughout the hiring process - please let us know if you need any.","description_format":"text","description_chars":4302,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Agents","Code Intelligence","AI Development Tools"],"lifecycle":[{"event":"open","at":"2026-08-06T18:19:30Z"}],"visa":[],"liveness":{"score":23,"band":"cold","label":"Long shot","p_open":1,"p_active":0.522,"p_room":0.44,"age_days":71,"expected_fill_days":53,"reasons":["conf:3","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":300000,"is_top_pay":true},"html_url":"https://alion.io/job/cognition-security-engineer","json_url":"https://alion.io/job/cognition-security-engineer.json","meta":{"generated_at":"2026-10-18T05:50:58Z","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":8733,"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":48342},"rest":"https://alion.io/mcp/rest/get_company?id=48342"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcognition-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%2Fcognition-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%2Fcognition-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/cognition-security-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcognition-security-engineer"}]}
