Clay's mission is to be the engine those companies use to grow to their full potential.\nClay predicts the next best action for your business and then helps you take it. We started by aggregating the best data for B2B companies. Then, we built the infrastructure to run any personalized campaign on top of it, including emails, ads, landing pages, and workflows that make reps more productive. Now, we're building agents that can help grow your company for you. We're already helping thousands of customers - including Anthropic, OpenAI, Google, and Visa - go to market with unique data, signals, and AI research.\nIn 2026, we raised a $115M Series D at $7.1B Valuation led by Wellington - and are on track to cross $200M in revenue this quarter. We also launched a $1M Scholarship fund for GTME Education.\nSome things to know about us:\nOur community includes 17,000+ customers, 200+ integration partners, 125+ agencies, 50+ Clay clubs, and 30k members on Slack.\n\nOur culture is unique inside and outside of work. Our team members are also DJs, activists, writers, clowns, marathoners, skydivers, psychedelic therapists, social workers, and more.\n\nAll employees can work with world-class coaches who specialize in creativity, management, and more.\n\nOur operating principles - including negative maintenance and non-attached action - guide our work. Read more about them here.\n\nRead about us in the NYT, Forbes, First Round Review, and more.\n\nHear from our employees directly on our Glassdoor page!\nSecurity Engineering @ Clay\nWe're building a modern security organization from the ground up. We're hiring senior or staff-level security engineers who are strong software engineers first, with deep expertise in either Cloud Security or Application Security and working knowledge across both.\nThis is a hands-on role. You'll spend significant time writing production code-security tooling, detection systems, remediation pipelines, and frameworks that make secure defaults the easiest path. You'll also help define how we leverage modern automation, including frontier AI models (e.g. Mythos), to scale security operations: autonomously discovering vulnerabilities, reviewing AI-generated code, and building detection systems that understand context and intent.\nWhat You'll Do\nBuild security primitives, tooling, and automation that scale with the product and engineering org\n\nDefine and implement our strategy for modern security workflows: AI-assisted vulnerability discovery, automated code review, threat detection, and remediation\n\nCollaborate with Infrastructure and Product Engineering to make secure defaults the easiest path\n\nOwn projects end to end: design, implementation, rollout, and measurement\n\nCloud Security\nSecure our cloud environment (IAM, network policies, container security, secrets management, and misconfiguration prevention).\n\nDefine and enforce least-privilege access patterns across services and humans.\n\nImprove cloud visibility and control using infrastructure-as-code and cloud security tooling (we currently use Terraform, AWS Config, and AWS Security Hub).\n\nDevelop preventative controls and safe deployment patterns that reduce the probability and blast radius of incidents.\n\nApplication Security\nLead secure design and secure coding practices, and prevent common vulnerability classes.\n\nPerform architecture reviews and code-level security reviews, and work hands-on with engineers to ship fixes.\n\nOwn the vulnerability discovery and validation lifecycle: static and dynamic analysis, dependency checks, pen tests, and bug bounties. Integrate modern automated detection systems (including Claude Mythos-class models) to find vulnerabilities at scale.\n\nBuild and deploy security agents and automated workflows that can scan codebases, propose fixes, and in some cases autonomously deploy security patches.\n\nBuild frameworks and reusable components for authentication, authorization, and secure-by-default patterns.\n\nDefine practical policies and controls for code generation tools and coding agent changes, so they can be used safely and consistently.\n\nWhat You'll Bring\nStrong software engineering fundamentals and a track record of shipping production systems\n\nDeep expertise in either cloud security or application security, with the ability to flex into the adjacent domain\n\nAbility to build, not just advise: You translate risk into concrete engineering work and ship solutions\n\nComfort with ambiguity: You thrive when building from first principles and defining what good looks like\n\nForward-thinking about tooling: Interest in leveraging modern automation and AI to scale security operations while maintaining engineering rigor\n\nOut of Scope\nThis is not an IT helpdesk or general operations role. We partner with other teams and vendors for routine operational work so you can stay focused on building scalable security foundations.","description_format":"text","description_chars":4946,"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":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Sales Enablement","Lead Generation","Marketing & Sales AI","B2B Company & Contact Data"],"lifecycle":[{"event":"open","at":"2026-04-16T13:10:07Z"},{"event":"close","at":"2026-08-13T11:28:03Z"},{"event":"reopen","at":"2026-09-10T04:48:34Z"}],"visa":[],"liveness":{"score":11,"band":"cold","label":"Long shot","p_open":1,"p_active":0.392,"p_room":0.28,"age_days":203,"expected_fill_days":84,"reasons":["conf:0","velocity","win:tail","crowd:"],"computed_at":"2026-11-06T05:58:05Z"},"pay":{"stated_usd_annual":300000,"is_top_pay":true},"html_url":"https://alion.io/job/clay-security-engineer","json_url":"https://alion.io/job/clay-security-engineer.json","meta":{"generated_at":"2026-11-06T22:16:06Z","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":180,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-07T00:00:00Z"}},"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":1484},"rest":"https://alion.io/mcp/rest/get_company?id=1484"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fclay-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%2Fclay-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%2Fclay-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/clay-security-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fclay-security-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3385}},{"tool":"search_jobs","arguments":{"company":"clay.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3385},"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.
