The challenge now is modernising security to stop AI-enabled threats, whether they come from internal agents going rogue or from attackers using AI to become more dangerous.\nRefractal was founded on cybersecurity and AI expertise from MIT, Microsoft, NASA and the U.S. Navy. Our product lets organisations detect AI-enabled threats at low cost without sacrificing detection quality. We take a practical approach to AI risk, combining proven cybersecurity methods with frontier AI security research.\nToday, we work with governments and organisations that can't afford to get security wrong. We're backed by leading deep-tech and cybersecurity investors and are growing the team to deliver on this mission.\nThe role\nYou'll lead offensive security research against AI agents and the infrastructure around them, and work with our engineers to turn your findings into detections, evaluations and defences in the product.\nWhat you'll do\nRed-team AI agents across browser, code, enterprise and multi-agent environments.\n\nResearch prompt injection, tool abuse, memory poisoning, identity and data-exfiltration attack chains.\n\nBuild automated attack tooling and reusable evaluation suites that run in CI and for customers.\n\nTurn findings into detection rules, classifiers and policy controls with our engineers.\n\nLead customer assessments and write findings that security leaders can act on.\n\nSuccess in your first six months\nYou've set a research agenda and delivered findings that changed the product.\n\nA growing regression suite captures the attack techniques you've found.\n\nCustomers have received assessments with clear, reproducible evidence.\n\nAbout you: essential\n6+ years in offensive security, application security, red teaming or vulnerability research.\n\nA record of original findings, such as CVEs, bug bounties, published research or conference talks.\n\nHands-on experience attacking LLM applications or agents, including tool calling, retrieval, memory and permissions.\n\nStrong Python and a systems language, with a habit of building your own tooling.\n\nClear communication of rigorous findings to engineers and executives.\n\nNice to have\nWorking knowledge of MITRE ATLAS or the OWASP Top 10 for LLM applications.\n\nMontenegrin, Serbian, Bosnian or Croatian.\n\nOur values\nRadical transparency. We believe the best work happens when everyone feels able to give and receive honest, constructive feedback.\nPublic service. We see AI security as a form of public service. Getting the AI transition right means putting the right infrastructure in place to manage the threats that come with it, and our work helps protect the institutions and services society depends on.\nFail fast. We test ideas early, seek feedback and learn quickly. We experiment rapidly and change course when something isn't working, without compromising on security.\nPragmatism, not dogmatism. We choose approaches based on how well they solve the problem. That means combining established cybersecurity methods with frontier AI research, questioning our assumptions, and changing our minds when the evidence changes.\nCompensation and benefits\nSalary: €40,000-€95,000 gross per year\n\nCompetitive equity to share in Refractal's growth\n\nPension contribution\n\nPrivate medical and dental cover\n\nVisa and relocation support","description_format":"text","description_chars":3484,"description_truncated":false,"requirements":{"experience_years_min":6,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":["Artificial Intelligence","Cybersecurity","Penetration Testing","Cybersecurity AI"],"lifecycle":[{"event":"open","at":"2026-10-27T15:00:00Z"}],"visa":[],"liveness":{"score":77,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.861,"p_room":0.9,"age_days":21,"expected_fill_days":35,"reasons":["conf:0","velocity","win:mid"],"computed_at":"2026-10-30T05:48:23Z"},"pay":{"stated_usd_annual":106240,"is_top_pay":false},"html_url":"https://alion.io/job/refractal-senior-ai-security-researcher","json_url":"https://alion.io/job/refractal-senior-ai-security-researcher.json","meta":{"generated_at":"2026-10-30T12:03:17Z","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":17359,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-31T00:00:00Z"}},"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":4403779},"rest":"https://alion.io/mcp/rest/get_company?id=4403779"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Frefractal-senior-ai-security-researcher"},{"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%2Frefractal-senior-ai-security-researcher"},{"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%2Frefractal-senior-ai-security-researcher"},{"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/refractal-senior-ai-security-researcher\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Frefractal-senior-ai-security-researcher"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3339522}},{"tool":"search_jobs","arguments":{"company":"refractal-ai.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3339522},"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.
