At a glance

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.

Core Platform builds the foundations every other team at ElevenLabs builds on, including how users, workspaces, and permissions work across products.
The systems sit on the path of every request and are relied on by millions of users and enterprise customers, making correctness, security, and safe rollout essential.

Building and improving the building blocks customers touch directly, such as API keys, login experience, analytics, admin tooling, and workspace security.
Working closely with Sales, FDEs, and customer teams to turn enterprise and self-serve feedback into the right improvements, and helping large customers with complex organisational structures.
Shipping customer-facing features end to end, from backend services to the admin and settings UI.
Designing and building generic resource and permissioning services that product teams use to build features safely and quickly.
Solving hard, largely greenfield problems at scale, for example how a customer with a million agents assigns and manages access.
Working across product teams to understand their needs, and driving adoption with changes that don't require every team to rework their code.
Scoping work as part of a large existing system, including understanding what exists, what could go wrong on rollout, whether a migration is needed, and how downstream teams are affected.
Rolling out changes safely and with minimal disruption to existing users, teams, or systems.
Debugging and operating what you build, working from customer reports, logs, and code.
Owning features from scoping to completion, with the support of experienced engineers who are happy to mentor.

Expertise in Python.
A strong background in backend development, with comfort working across the stack where the work needs it.
Experience with common software and system design patterns and infrastructure, including APIs, cloud infrastructure tools, storage solutions, and data structures.
Strong test design and security fundamentals.
Care and attention to detail when changing live, business-critical systems, and the ability to learn a large existing codebase quickly.
Comfort with ambiguity, including working out what should be built and prioritising among competing signals.

Experience with authentication, authorization, or permissioning (OAuth, SSO/SCIM, RBAC or similar).
Experience with Kubernetes.
Experience building internal platforms or services used by other engineering teams.
