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 deploying and optimizing our frontier AI models in production. The quality of our models only matters if they can be served fast, reliably, and at scale. You will own the systems that turn research breakthroughs into real-time products used by millions. You will thrive in this role if you enjoy:\nDeploying state-of-the-art models to production and owning the path from research checkpoint to serving infrastructure.\n\nOptimizing inference performance across the stack, including latency, throughput, and cost, using techniques such as quantization, distillation, KV-cache optimization, batching strategies, and custom kernels.\n\nBuilding and tuning high-performance serving systems for real-time, streaming workloads where every millisecond matters.\n\nCreating tooling and infrastructure that lets researchers ship new models to production quickly, safely, and with confidence in their performance characteristics.\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 deploying and serving ML models in production, ideally for latency-sensitive or real-time applications.\n\nStrong engineering skills in GPU programming and inference optimization (e.g., CUDA, Triton, TensorRT, or serving frameworks such as vLLM or SGLang).\n\nThe capacity to autonomously profile, diagnose, and eliminate bottlenecks across the serving stack, from model architecture to kernels to orchestration, and to build the tooling to measure it.\n\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":4702,"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":"2026-08-28T10:12:39Z"}],"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":"2026-10-17T06:21:15+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":50,"band":"ok","label":"Likely open","p_open":1,"p_active":0.831,"p_room":0.6,"age_days":49,"expected_fill_days":63,"reasons":["conf:3","velocity","win:late","crowd:brand"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/elevenlabs-research-engineer-inference","json_url":"https://alion.io/job/elevenlabs-research-engineer-inference.json","meta":{"generated_at":"2026-10-17T18:36:13Z","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":1428,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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-inference"},{"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-inference"},{"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-inference"},{"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-inference\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Felevenlabs-research-engineer-inference"}]}
