Our adversarial red teaming, model evaluations, and intelligence collection enable engineering, safety, and security teams to stay ahead of evolving threats and deploy AI systems safely.\nOur client’s team is responsible for identifying and investigating misuses of their products - especially new types of abuse-and creating systems of defence to address them. Part of this team specialises in the latter, and they need additional support to help them monitor abuse on product launches and design and build scaled detection, review, enforcement, and measurement for uncovered risks. This position is a Full-Time (40 hours per week), contract position.\nAbout The Role:\nProtection Science Engineering is an interdisciplinary role mixing data science, machine learning, investigation, and policy/protocol development. As a Protection Scientist Engineer within the client team, you will assist in designing and building systems to proactively identify and enforce on abuse on their AI products. This includes ensuring they have robust abuse monitoring in place for new products, sustaining monitoring for existing products, and prototyping and incubating systems of defense against the highest risk harms. You will also respond to and investigate critical escalations, especially those that are not caught by existing safety systems. This will require developing understanding of the products and data, and working cross-functionally with product, policy, and engineering teams. \nYou will need a strong ability to use SQL and python to query, transform, and understand data, and to build and improve prototype detection. An investigative mindset is key, with experience in identifying and enforcing on bad actors (in any industry). A background including data science, machine learning and classification basics, AI, and/or threat investigation is a plus.\nThis is a remote position, based in London, UK. The position includes participation in an on-call rotation that will involve resolving urgent escalations outside of normal work hours, for at least 7 consecutive days per quarter. Some detection and investigations may involve exposure to sensitive and distressing content, including sexual, violent, or otherwise-disturbing material. \nIn This Role, You Will:\nScope and implement abuse monitoring requirements for new product launches.\nImprove processes to sustain monitoring operations for existing products, including developing approaches to automate monitoring subtasks. \nPrototype and mature into production systems of detection, review, and enforcement of abuse for major harms.\nWork with Product, Policy, Ops, and Investigative teams to understand key risks and how to identify and address them, and with Engineering teams to ensure we have sufficient data and scaled tooling. \nRequirements:\nAbility to work remotely on GMT and must be geographically located in the UK.\nQuantitative and coding background , including statistics/metrics and proficiency in python and SQL.\nExperience in identifying (and ideally enforcing on) bad actors with scaled tooling.\nAbility to be on-call approximately once a quarter that will involve resolving urgent escalations outside of normal work hours, including occasional evenings and weekends\nAbility to rapidly context switch across domains, modalities, and abuse areas, to include high severity areas like violent activities and child safety\nExcited to work in a fast paced, ambiguous, and purposeful space with high impact across users and beyond, and to learn quickly. \nDesired Qualities (but not required):\nBackground in machine learning and classification, especially on novel or poorly understood behaviours.\nExperience scaling and automating processes, especially with language models.\nExperience working with scaled labellers or reviewers, particularly at scale.\nFamiliarity with one of the following topics/areas: AI safety, child safety, abuse by nation state and other malicious actors, digital mental health, fraud abuse, radicalization/persuasion/grooming; hateful activities and groups.","description_format":"text","description_chars":4216,"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":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Threat Intelligence","Cybersecurity AI","AI Safety & Alignment"],"lifecycle":[{"event":"open","at":"2026-10-04T00:35:21Z"}],"visa":[],"liveness":{"score":3,"band":"cold","label":"Long shot","p_open":1,"p_active":0.115,"p_room":0.28,"age_days":293,"expected_fill_days":27,"reasons":["conf:2","stale_co","ghost","win:tail","crowd:"],"computed_at":"2026-10-13T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/10a-labs-protection-scientist-engineer","json_url":"https://alion.io/job/10a-labs-protection-scientist-engineer.json","meta":{"generated_at":"2026-10-13T17:50:56Z","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":27277,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-14T00:00:00Z"}},"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":3857131},"rest":"https://alion.io/mcp/rest/get_company?id=3857131"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2F10a-labs-protection-scientist-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%2F10a-labs-protection-scientist-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%2F10a-labs-protection-scientist-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/10a-labs-protection-scientist-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2F10a-labs-protection-scientist-engineer"}]}
