Job description

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

The Music team owns music and sound effects end to end at ElevenLabs. We turn research breakthroughs into APIs and creative tools, from the backend systems that bring in new models to the interfaces creators use inside ElevenCreative. Five new research engineers have just joined the music research group, and models for stem separation and MIDI transcription are in progress.

You’ll join as a Full-Stack Engineer with a backend lean. You’ll work with research and research engineering to bring model improvements into production, and build and run the APIs behind them. You’ll also sync with go-to-market to decide which features, including bespoke enterprise ones, get built next. Occasionally you’ll join customer calls when a customer wants someone technical.

Engineers act as PMs. You’ll be handed ambiguous goals and expected to break them down. That means working through the legal questions, choosing the engineering approach, and planning the launch with growth. Models set the limits, so you’ll design systems that let a better model be swapped in later. Engineering is often only half the job.

Requirements

• A strong Full-Stack Engineer with a backend lean. You’ve built and shipped production APIs and backend systems.
• A product decomposition mindset. You’ve taken a vague goal, weighed trade-offs and shipped without analysis paralysis.
• Proactive ownership. You drive work end to end without a ticket board or someone assigning tasks.
• Comfortable working across research, legal, safety, growth, design and enterprise customers.
• Genuinely excited about music and AI. You’re the kind of person who prototypes ideas for fun and pushes the good ones into production.

Bonus: music or audio experience (even as a hobby), or experience shipping ML models into production.

Location

This role is remote-first, so it can be executed from anywhere in Europe or on the US East Coast, with the ability to operate in Central European timezones required. If you prefer, you can work from our offices in Dublin, London, New York and Warsaw.

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.
