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 are looking for a Research Engineer to join the research team at ElevenLabs, focused on the data infrastructure that powers our frontier AI models. The quality of our models is bounded by the quality and scale of the data behind them, and you will own the systems that make world-class data possible. You will thrive in this role if you enjoy:\nBuilding large-scale data pipelines for collecting, processing, filtering, and transforming datasets used to train state-of-the-art models.\n\nTraining models used in our data processing pipelines, such as classifiers, quality filters, and labeling models.\n\nDesigning data curation strategies such as deduplication, quality scoring, labeling, and augmentation that measurably improve model performance.\n\nCreating tooling and infrastructure that lets researchers explore and train on massive datasets quickly and reliably.\n\nRequirements\nWe do not require any formal certifications or degrees. Instead, we are seeking enthusiastic engineers who can showcase solving impressively hard problems with artifacts such as past projects, designs, or GitHub contributions. Ideally, you bring:\nExperience building data-intensive systems, ideally in support of machine learning training pipelines.\n\nStrong engineering skills in distributed data processing at scale (e.g., Kubernetes, or custom pipelines over large datasets).\n\nThe capacity to autonomously evaluate how data quality, composition, and curation affect model outcomes, and to build the tooling to measure it.\n\nBonus: Experience building or operating web crawlers.\nLocation\nThis role is remote and can be executed globally. If you prefer, you can work from our offices in London, New York, San Francisco, and Warsaw.\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":4536,"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 States","iso":"US","kind":"country"},{"name":"United Kingdom","iso":"GB","kind":"country"},{"name":"Bulgaria","iso":"BG","kind":"country"},{"name":"Poland","iso":"PL","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Conversational AI","Speech & Audio AI","Generative Audio & Music"],"lifecycle":[{"event":"open","at":"2026-09-05T15:42:43Z"},{"event":"close","at":"2026-10-06T18:46:56Z"},{"event":"reopen","at":"2026-10-20T02:16:11Z"}],"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":"2026-10-27T06:21:15+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":47,"band":"ok","label":"Likely open","p_open":1,"p_active":0.784,"p_room":0.6,"age_days":59,"expected_fill_days":60,"reasons":["conf:3","velocity","win:late","crowd:brand"],"computed_at":"2026-10-27T05:46:45Z"},"pay":null,"html_url":"https://alion.io/job/elevenlabs-research-engineer-data-infrastructure","json_url":"https://alion.io/job/elevenlabs-research-engineer-data-infrastructure.json","meta":{"generated_at":"2026-10-27T16:14:32Z","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":5515,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-28T00:00:00Z"}},"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-research-engineer-data-infrastructure"},{"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-research-engineer-data-infrastructure"},{"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-research-engineer-data-infrastructure"},{"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-research-engineer-data-infrastructure\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Felevenlabs-research-engineer-data-infrastructure"}]}
