As our first dedicated security hire in Singapore, you'll own security end-to-end: hardening the applications our users touch, the infrastructure our agents run on, and the new and evolving attack surface introduced by autonomous AI agents themselves.\nThis is a hands-on, builder-style role. You won't be writing policy documents from an ivory tower; you'll be reading code, fixing it, and shipping the tooling that keeps Simular safe as we scale.\nWhat you'll do\nOwn application security across our product surface: threat modeling, secure code review, SAST/DAST, dependency and supply-chain hygiene\nHarden our cloud and infrastructure: AWS/GCP configuration, Kubernetes, secrets management, network boundaries, CI/CD pipeline security\nBuild the security foundation for our agent platform: sandboxing, permission boundaries, prompt-injection defenses, data exfiltration controls, and safe tool execution\nPartner with engineering and research to bake security into product design from day zero, not bolted on later\nRun incident response and lead investigations when things go wrong; build the playbooks so the next one is faster\nDrive vendor reviews, customer security questionnaires, and the compliance work needed as we move upmarket (SOC 2, ISO, etc.)\nEstablish the security culture: lightweight processes, useful tooling, clear ownership; scrappy, not bureaucratic\nYou might be a fit if\nYou have a BS/MS in Computer Science or equivalent experience, with 3-6 years in security engineering\nYou're a strong engineer first: comfortable shipping code in Python, Go, or TypeScript, not just reviewing others'\nYou have hands-on experience across two or more of: AppSec, cloud security (AWS/GCP), container/Kubernetes hardening, CI/CD security\nYou understand modern threat models: supply-chain attacks, identity and secrets, web app vulnerabilities, infrastructure misconfiguration\nYou're genuinely curious about AI and agent security: how prompt injection works, how to sandbox autonomous tool use, how to reason about data flow in agentic systems\nYou thrive as the first security hire: you can prioritize ruthlessly, build from zero, and earn trust by shipping rather than blocking\nBonus: red-team or offensive security background, experience securing ML/AI pipelines, or prior early-stage startup experience","description_format":"text","description_chars":2598,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Agents","Multimodal AI","AI Research Labs"],"lifecycle":[{"event":"open","at":"2026-06-18T13:26:43Z"}],"visa":[],"liveness":{"score":6,"band":"cold","label":"Long shot","p_open":1,"p_active":0.207,"p_room":0.28,"age_days":136,"expected_fill_days":30,"reasons":["conf:2","stale_co","ghost","win:tail","crowd:"],"computed_at":"2026-11-02T06:13:15Z"},"pay":null,"html_url":"https://alion.io/job/simular-security-engineer","json_url":"https://alion.io/job/simular-security-engineer.json","meta":{"generated_at":"2026-11-02T21:13:38Z","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":29622,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-03T00:00:00Z"}},"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":34173},"rest":"https://alion.io/mcp/rest/get_company?id=34173"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsimular-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%2Fsimular-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%2Fsimular-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/simular-security-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsimular-security-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":86003}},{"tool":"search_jobs","arguments":{"company":"simular.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":86003},"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);
