Today, we serve millions of users and thousands of businesses - from fast-growing startups to large enterprises like Deutsche Telekom and Meta. Our investors are some of the world's most prominent, including Andreessen Horowitz, ICONIQ Growth and Sequoia. We've raised $781M in funding and our last valuation was $22B - multiples of 11, always.\nWe have expanded from voice into three main platforms:\nElevenAgents enables businesses to deliver seamless and intelligent customer experiences, with the integrations, testing, monitoring, and reliability necessary to deploy voice and chat agents at scale.\n\nElevenCreative empowers creators and marketers to generate and edit speech, music, image, and video across 70+ languages.\n\nElevenAPI gives developers access to our leading AI audio foundational models.\n\nEverything we do is the result of the creativity and commitment of our team - builders doing the best work of their lives. We are researchers, engineers, and operators. IOI medalists and ex-founders. If you want to work hard and create lasting positive impact, we want to hear from you.\nHow we work\nHigh-velocity: Rapid experimentation, lean autonomous teams, and minimal bureaucracy.\n\nImpact not job titles: We don’t have job titles. Instead, it’s about the impact you have. No task is above or beneath you.\n\nAI first: We use AI to move faster with higher-quality results. We do this across the whole company-from engineering to growth to operations.\n\nExcellence everywhere: Everything we do should match the quality of our AI models.\n\nGlobal team: We prioritize your talent, not your location.\n\nWhat we offer\nInnovative culture: You’ll be part of a generational opportunity to define the trajectory of AI, surrounded by a team pushing the boundaries of what’s possible.\n\nGrowth paths: Joining ElevenLabs means joining a dynamic team with countless opportunities to drive impact - beyond your immediate role and responsibilities.\n\nLearning & development: ElevenLabs proactively supports professional development through an annual discretionary stipend.\n\nSocial travel: We also provide an annual discretionary stipend to meet up with colleagues each year, however you choose.\n\nAnnual company offsite: Each year, we bring the entire team together in a new location - past offsites have included Croatia and Italy.\n\nCo-working: If you’re not located near one of our main hubs, we offer a monthly co-working stipend.\n\nAbout the role\nWe're looking for a Data Scientist to take ownership of the datasets and evaluation workflows that underpin our AI Safety work. You'll turn real-world product data into reliable, well-structured datasets for training and evaluating models, and help build the processes and infrastructure to continuously assess how those models perform in production.\nThis is a hands-on role at the intersection of data science, ML, AI safety, and policy. You'll work closely with safety researchers, engineers, and policy specialists to translate complex safety requirements into practical data and evaluation systems - starting hands-on with collection, analysis, and labelling, then building the methodologies, contributor networks, and quality standards that let this work scale.\nIn this role, you will\nOwn safety datasets end-to-end: collection, cleaning, labelling, quality control, versioning, and readiness for training and evaluation.\n\nTranslate safety policy into clear, consistent labelling and evaluation criteria, working closely with policy specialists.\n\nDesign and manage labelling processes, including sourcing, onboarding, and overseeing external contributors to a high quality bar.\n\nBuild evaluation workflows for models in production, using real-world data to track performance and surface issues.\n\nDevelop lightweight Python/SQL pipelines and tooling to make data work faster and reproducible, partnering with ML engineers on what \"training-ready\" looks like.\n\nWho you are\nExperience as a Data Scientist, or similar, working with real-world datasets and ML models.\n\nStrong grasp of what makes a good dataset: collection, cleaning, sampling, labelling, quality control, evaluation.\n\nComfortable with Python and SQL for analysis and practical data workflows.\n\nStrong critical thinking and judgement - comfortable with ambiguity and nuance, and able to turn complex guidelines into consistent, scalable decisions.\n\nAutonomous and a clear communicator, able to work across disciplines (policy, engineering, research) in a fast-moving, still-forming environment.\n\nBonus points\nExperience in AI safety, trust & safety, content moderation, or fraud/abuse detection.\n\nExperience building datasets or evaluation frameworks, or with adversarial/safety-focused ML.\n\nExperience managing human-in-the-loop labelling processes, dataset versioning, or ML pipeline tooling.\n\nExperience operationalising guidelines with policy or legal teams.\n\nLocation\nThis role is based in London, where you'll work closely with our AI Safety and Policy teams.\nWe are an equal opportunity employer and do not discriminate on the basis of race, religion, national origin, gender, sexual orientation, age, veteran status, disability or other legally protected statuses.","description_format":"text","description_chars":5356,"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":["Professional development"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Conversational AI","Speech & Audio AI","Generative Audio & Music"],"lifecycle":[{"event":"open","at":"2026-09-01T18:23:27Z"},{"event":"close","at":"2026-11-05T18:11:52Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"evidence":"Licensed UK visa sponsor (Skilled Worker)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Skilled Worker","cap_exempt":false,"checked_at":"2026-11-05T06:29:30+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":null,"pay":null,"html_url":"https://alion.io/job/elevenlabs-data-scientist-ai-safety","json_url":"https://alion.io/job/elevenlabs-data-scientist-ai-safety.json","meta":{"generated_at":"2026-11-05T19:46:06Z","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":26555,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-06T00:00:00Z"}},"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":266},"rest":"https://alion.io/mcp/rest/get_company?id=266"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Felevenlabs-data-scientist-ai-safety"},{"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%2Felevenlabs-data-scientist-ai-safety"},{"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%2Felevenlabs-data-scientist-ai-safety"},{"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/elevenlabs-data-scientist-ai-safety\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Felevenlabs-data-scientist-ai-safety"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":186496}},{"tool":"search_jobs","arguments":{"company":"elevenlabs.io","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":186496},"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.
