We build next-generation defenses through high-fidelity research platforms that simulate and monitor real-world AI security scenarios.\nAs AI systems become more powerful, we focus on staying ahead of emerging threats and vulnerabilities, ensuring these transformative technologies can be deployed safely and securely.\nAbout the Role\nAs a Software Engineer at Irregular, you will take ownership of designing, building, and scaling the production systems that power our evaluation and security platform for frontier AI models.\nYour work will focus on creating robust, resilient, and high-performance infrastructure-whether that’s distributed pipelines, backend services, or tooling that supports our research teams.\nThis role is engineering-first with a strong research and cyber component. You will develop systems that must run reliably in production, integrate with external partners, and support large-scale data, experiments, and automated evaluations. You’ll drive architectural decisions, lead technical implementations, and shape how our platform evolves.\nRepresentative Responsibilities:\nArchitecting and scaling production-grade systems and workflows.\n\nBuilding backend services, APIs, and monitoring tools for large-scale model evaluations.\n\nDesigning infrastructure that supports research experiments at scale.\n\nImplementing agent frameworks in production environments\n\nDesigning and building challenges that measure a model’s ability to evade discovery, allowing us to see if models can operate on remote systems while avoiding detection by common defensive security tools.\n\nYou may be a good fit if you:\nHave strong software engineering fundamentals and multiple years of production experience.\n\nHave experience working in multidisciplinary teams, and can adapt to rapidly evolving challenges.\n\nEnjoy working at the intersection of engineering and applied research.\n\nAre interested in AI and cybersecurity (experience in machine learning or cybersecurity is a plus but not necessary).\n\nCare about the societal impacts of your work.","description_format":"text","description_chars":2212,"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":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Cybersecurity AI","AI Safety & Alignment"],"lifecycle":[{"event":"open","at":"2026-09-06T11:37:34Z"},{"event":"open","at":"2026-09-26T06:45:00Z"}],"visa":[],"liveness":{"score":5,"band":"cold","label":"Long shot","p_open":1,"p_active":0.192,"p_room":0.28,"age_days":331,"expected_fill_days":36,"reasons":["conf:0","stale_co","ghost","win:tail","crowd:"],"computed_at":"2026-10-24T06:02:35Z"},"pay":null,"html_url":"https://alion.io/job/irregular-senior-software-engineer","json_url":"https://alion.io/job/irregular-senior-software-engineer.json","meta":{"generated_at":"2026-10-25T03:53:22Z","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":5021,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-26T00:00:00Z"}},"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":178417},"rest":"https://alion.io/mcp/rest/get_company?id=178417"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Firregular-senior-software-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%2Firregular-senior-software-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%2Firregular-senior-software-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/irregular-senior-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Firregular-senior-software-engineer"}]}
