Full-Stack Engineer - Creative Agents

About ElevenLabs ElevenLabs is an AI research and product company transforming how we interact with technology. We launched in January 2023 with the first human-like AI voice model. 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. We have expanded from voice into three main platforms: • ElevenAgents 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. • ElevenCreative empowers creators and marketers to generate and edit speech, music, image, and video across 70+ languages. • ElevenAPI gives developers access to our leading AI audio foundational models. Everything 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. How we work • High-velocity: Rapid experimentation, lean autonomous teams, and minimal bureaucracy. • Impact not job titles: We don’t have job titles. Instead, it’s about the impact you have. No task is above or beneath you. • AI first: We use AI to move faster with higher-quality results. We do this across the whole company—from engineering to growth to operations. • Excellence everywhere: Everything we do should match the quality of our AI models. • Global team: We prioritize your talent, not your location. What we offer • Innovative 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. • Growth paths: Joining ElevenLabs means joining a dynamic team with countless opportunities to drive impact – beyond your immediate role and responsibilities. • Learning & development: ElevenLabs proactively supports professional development through an annual discretionary stipend. • Social travel: We also provide an annual discretionary stipend to meet up with colleagues each year, however you choose. • Annual company offsite: Each year, we bring the entire team together in a new location – past offsites have included Croatia and Italy. • Co-working: If you’re not located near one of our main hubs, we offer a monthly co-working stipend. About the role We are looking for a full-stack engineer to help build the next generation of Creative Agents at ElevenLabs. Our ambition is to make agents a primary way people create across ElevenCreative. We are building systems that turn ideas into high-quality audio, image and video, bringing models and creative tools together without requiring users to become prompting experts. The creative agent is already live. You will join a small team where engineers own complete problems across the full stack: frontend, backend, agent architecture and infrastructure. You should be equally comfortable building a user-facing feature, designing the services behind it, and deploying and operating the system in production. You will combine strong engineering with product judgement, taking ideas from early prototypes through to reliable features and using real customer feedback to guide what we build next. Your responsibilities will include: • Designing and building complete agent-powered features, from frontend interfaces and application state to backend services, APIs and data storage. • Developing agent capabilities and integrations, including model orchestration, creative tools and reliable asynchronous workflows for audio, image and video generation. • Building and operating the infrastructure behind these features, improving quality, performance, scalability and security through evaluations, monitoring and testing. • Owning a problem area from discovery and prototyping to deployment and ongoing operation, working closely with product, design and engineering. You will help shape both what the agent can do and how people use it across ElevenCreative. The work combines substantial greenfield development with improving a live product, with room to experiment and directly influence the product’s direction. Location: This 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. #LI-Remote Requirements We care about evidence of exceptional engineering: products you have shipped, difficult problems you have solved, and systems you have owned. We are looking for: • Strong engineering skills across both frontend and backend, with a track record of independently building complete production applications. • Confidence designing user interfaces, backend services, APIs and data models, and understanding how these components work together as a system. • Practical experience with cloud infrastructure, deployment, asynchronous processing, testing and observability, with the ability to debug and resolve problems across the full stack. • Evidence of end-to-end ownership, strong product judgement and clear communication, taking ambiguous problems from technical design through to shipping and ongoing operation. You should be excited about creative agents and comfortable learning quickly as models, tools and user needs evolve. Hands-on experience building production agents, evaluations, MCP integrations, creative editors or multimodal products would be particularly valuable, as would experience building in a small, fast-moving team.
