As enterprises accelerate AI agent adoption, we are establishing the security framework for how AI agents are secured and governed at enterprise scale.\nWe deliver full-lifecycle visibility, governance, detection, prevention, and response for AI agents from build time to runtime, across SaaS, home-grown platforms, and end-user devices. Backed by $180M+ in total funding, including a $125M Series C led by Norwest, with participation from SoftBank Vision Fund 2 and Microsoft's M12, Zenity is trusted by Fortune 500 and Global 2000 enterprises worldwide.\nJoin us in shaping how AI agents are secured at enterprise scale.\nAbout the Role:\nWe're looking for a Senior Applied AI Scientist to sit at the frontier of AI security - turning emerging threats into the detection models that protect how AI is used inside the world's largest organizations. You'll be part of the AI Security Research department, working hand-in-hand with security researchers to translate threat intelligence into trainable signals that catch malicious behavior and security risks across the AI-powered workflows of Fortune 500 companies.\nYou'll bring deep technical versatility - reaching for classical ML, deep learning, or agentic based approaches based on what the problem demands, and the evaluation rigor to know when a model is truly ready for the real world. If you want to define what AI security engineering looks like, not just practice it, this role is for you.\nWhat You’ll Do\nResponsibilities:\nBuild, train, and ship detection models end-to-end, from raw data to production\nChoose the right method for each problem - traditional ML, deep learning, fine-tuned LLMs, agents or heuristics - based on theoretical insights turned into practical results.\nPartner with security researchers to turn security research outputs and domain expertise into detection capabilities\nOwn evaluation: design benchmarks, build labeled datasets, and define production standards\nMonitor models in production across all paradigms - ML, deep learning, LLM-based, and agentic systems to track degradation and ensure reliability\nIterate fast, with a tight feedback loop between model performance and product outcomes\nRequirements\nRequirements:\n5 years of hands-on ML and deep learning experience, with a track record of shipping, debugging, and diagnosing models in production\nData-first mindset: you know how to define the right evaluation criteria for each model - before and after shipping, to ensure it delivers real quality and value in production\nHands-on experience building and deploying agentic AI systems to production\nProficiency in Python; experience with PyTorch, scikit-learn, HuggingFace, or equivalent\nPractical, applied mindset - focused on the problem, success metrics and impact, not lab research.\n\nBackground in security, trust & safety, or content moderation - an advantage","description_format":"text","description_chars":2995,"description_truncated":false,"requirements":{"experience_years_min":5,"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":["Application Security","AI Governance & Compliance"],"lifecycle":[{"event":"open","at":"2026-09-25T12:11:42Z"}],"visa":[],"liveness":{"score":35,"band":"fade","label":"Fading","p_open":1,"p_active":0.781,"p_room":0.45,"age_days":34,"expected_fill_days":21,"reasons":["conf:3","velocity","win:tail"],"computed_at":"2026-10-30T05:48:23Z"},"pay":null,"html_url":"https://alion.io/job/zenity-senior-applied-ai-scientist","json_url":"https://alion.io/job/zenity-senior-applied-ai-scientist.json","meta":{"generated_at":"2026-10-30T22:21:27Z","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":13086,"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":63227},"rest":"https://alion.io/mcp/rest/get_company?id=63227"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fzenity-senior-applied-ai-scientist"},{"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%2Fzenity-senior-applied-ai-scientist"},{"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%2Fzenity-senior-applied-ai-scientist"},{"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/zenity-senior-applied-ai-scientist\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fzenity-senior-applied-ai-scientist"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":1221432}},{"tool":"search_jobs","arguments":{"company":"zenity.io","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":1221432},"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);
