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 $11B - 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're looking for a Developer Experience Engineer to join us in our goal of making the ElevenLabs developer experience the gold standard other companies look up to.

Additionally you'll help design and improve the ElevenLabs API, build developer tooling, and act as \"customer zero\" for new developer products.

This role is perfect for someone who enjoys open source software and jumping between multiple programming languages across the stack. This role is for engineers who are motivated by improving the developer experience—hands on keyboard, building the developer experience.
