The platform collects identity and business context across systems to investigate alerts and continuously learns your environment. Security experts validate decisions, feed insights into the platform, optimize detections, and take over in case of an incident.\nThe result: security teams move from firefighting to strategic work.\nWe're looking for a Senior Security Engineer to join our globally distributed, high-impact security engineering team. You will design and implement detection logic, investigate alerts, and automate response mechanisms. As an early hire, you'll work closely with our platform and AI teams to shape how autonomous threat detection and response is built and delivered at scale.\nResponsibilities:\nLead Investigations: Triage, analyze, and respond to alerts across cloud, endpoint, and network environments with automation-first principles.\nBuild Detections: Write detection logic and behavioral rules as code that is clear, testable, and scalable.\nAutomate Response Workflows: Develop Go-based automation for enrichment, containment, and remediation playbooks.\nDefine Detection-as-Code Practices: Implement a detection and response framework with strong engineering fundamentals (testing, CI/CD, version\ncontrol).\nCollaborate Across Functions: Partner with platform and AI teams to integrate detection logic into the broader Daylight stack.\nSupport DFIR: Participate in incident investigations and post-incident reviews; DFIR skills (memory, disk, or cloud forensics) are a strong plus.\nRequirements:\nSecurity Operations Experience: 3+ years in detection engineering, incident response, or blue team roles.\nAutomation Mindset: You automate what others manually repeat. Experience building or integrating automated response systems is key.\nCloud-Native Awareness: Familiarity with detecting and responding to threats in cloud environments (AWS, GCP, or Azure).\nDFIR Skills: Practical experience in digital forensics and incident response - logs, memory, containers, cloud.\nThreat-Informed Thinking: Comfort with attacker tactics and techniques (MITRE ATT&CK, behavioral detection, threat modeling).\n#LI-DNI","description_format":"text","description_chars":2544,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Security Operations","Managed Security","Cybersecurity AI"],"lifecycle":[{"event":"open","at":"2026-10-12T12:14:35Z"},{"event":"close","at":"2026-10-14T15:30:00Z"}],"visa":[],"liveness":null,"pay":null,"html_url":"https://alion.io/job/daylight-senior-security-engineer-3","json_url":"https://alion.io/job/daylight-senior-security-engineer-3.json","meta":{"generated_at":"2026-10-14T18:50:04Z","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":24489,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-15T00:00:00Z"}},"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":35979},"rest":"https://alion.io/mcp/rest/get_company?id=35979"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fdaylight-senior-security-engineer-3"},{"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%2Fdaylight-senior-security-engineer-3"},{"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%2Fdaylight-senior-security-engineer-3"},{"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/daylight-senior-security-engineer-3\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fdaylight-senior-security-engineer-3"}]}
