We do this across the whole company—from engineering to growth to operations.</p> </li> <li> <p><strong>Excellence everywhere: </strong>Everything we do should match the quality of our AI models.</p> </li> <li> <p><strong>Global team: </strong>We prioritize your talent, not your location.</p> </li> </ul> <h3>What we offer</h3> <ul> <li> <p><strong>Innovative culture:</strong> 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.</p> </li> <li> <p><strong>Growth paths: </strong>Joining ElevenLabs means joining a dynamic team with countless opportunities to drive impact - beyond your immediate role and responsibilities.</p> </li> <li> <p><strong>Learning &amp; development</strong>: ElevenLabs proactively supports professional development through an annual discretionary stipend.</p> </li> <li> <p><strong>Social travel</strong>: We also provide an annual discretionary stipend to meet up with colleagues each year, however you choose.</p> </li> <li> <p><strong>Annual company offsite: </strong>Each year, we bring the entire team together in a new location - past offsites have included Croatia and Italy.</p> </li> <li> <p><strong>Co-working</strong>: If you’re not located near one of our main hubs, we offer a monthly co-working stipend.</p> </li> </ul> <h3>About the role</h3> <p>We are looking for a backend-leaning full-stack engineer to help build the next generation of Creative Agents at ElevenLabs.</p> <p>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.</p> <p>The creative agent is already live. You will join a small team shaping its capabilities and architecture, with ownership from backend systems and agent infrastructure through to the customer-facing experience. You will help discover what works, turn experiments into reliable features, and use real customer feedback to guide what we build next.</p> <p><strong>Your responsibilities will include:</strong></p> <ul> <li> <p>Building production agents and expanding their capabilities through prompts, tool use, orchestration, new models and MCP integrations.</p> </li> <li> <p>Designing and operating reliable backend systems for asynchronous creative generation and long-running tasks, with strong performance, observability, scalability and security.</p> </li> <li> <p>Developing shared evaluations and live quality monitoring, including model-based assessment of image and video outputs.</p> </li> <li> <p>Owning features end to end, from identifying user needs and prototyping to shipping across the stack and supporting them in production, alongside product, design and engineering.</p> </li> </ul> <p>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 and operating a live product.</p> <h3>Requirements</h3> <p>We care about evidence of exceptional engineering: products you have shipped, difficult problems you have solved, and systems you have owned.</p> <p>We are looking for:</p> <ul> <li> <p>Strong backend engineering skills, experience operating production systems, and sound fundamentals in APIs, cloud infrastructure, storage and asynchronous processing.</p> </li> <li> <p>Hands-on experience developing agents, with an understanding of prompts, tools, execution logic, evaluations and the challenges of reliable, secure operation.</p> </li> <li> <p>Evidence of independent, end-to-end ownership and confidence working across the stack, including frontend delivery when needed.</p> </li> <li> <p>Good product judgement, clear communication and enthusiasm for creative agents.</p> </li> </ul> <p>We may also consider exceptional engineers with closely relevant experience. Familiarity with HTTP, WebSockets and asynchronous workers will help you build reliable communication between services and recover from failures.</p> <p>Experience with multimodal generation, creative editors, MCP, or building products in a small, fast-moving team would be particularly valuable.</p> <p><strong>Location:</strong></p> <p>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.</p> <p>#LI-Remote</p> <p>We 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.</p>
