Full-Stack Engineer (Backend Leaning) - 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 backend-leaning 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 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.

• Your responsibilities will include:
• - Building production agents and expanding their capabilities through prompts, tool use, orchestration, new models and MCP integrations.
• - Designing and operating reliable backend systems for asynchronous creative generation and long-running tasks, with strong performance, observability, scalability and security.
• - Developing shared evaluations and live quality monitoring, including model-based assessment of image and video outputs.
• - 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.
• 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.

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 backend engineering skills, experience operating production systems, and sound fundamentals in APIs, cloud infrastructure, storage and asynchronous processing.
• - Hands-on experience developing agents, with an understanding of prompts, tools, execution logic, evaluations and the challenges of reliable, secure operation.
• - Evidence of independent, end-to-end ownership and confidence working across the stack, including frontend delivery when needed.
• - Good product judgement, clear communication and enthusiasm for creative agents.
• 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.
• Experience with multimodal generation, creative editors, MCP, or building products in a small, fast-moving team would be particularly valuable.
• 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
• 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.
