Full-Stack Engineer (Backend Leaning) - Platform Engineering

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 team offsite: Each year, we bring your entire team together in a new location - past offsites have included Croatia, Italy and Cancún

• Co-working: If you’re not located near one of our main hubs, we offer a monthly co-working stipend.

About the role

Core Platform builds the foundations every other team at ElevenLabs builds on: how users, workspaces and permissions work across our products. Our systems sit on the path of every request and are relied on by millions of users and by enterprise customers, so correctness, security and safe rollout matter as much as speed.

We are hiring full stack engineers (backend leaning) for two focus areas. Depending on the team you join, your responsibilities might include:

Workspaces & User Management (serving external customers)

• Building and improving the building blocks customers touch directly: API keys, login experience, analytics, admin tooling, workspace security and more

• 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.

Permissions & Resources (serving ElevenLabs engineering teams)

• 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.

In both teams you will:

• Scope work as part of a large existing system: understand what exists, what could go wrong on rollout, whether a migration is needed, and how downstream teams are affected.

• Roll out changes safely and with minimal disruption to existing users, teams or systems.

• Debug and operate what you build, working from customer reports, logs and code.

• Own features from scoping to completion, with the support of experienced engineers who are happy to mentor.

Requirements

We do not require any formal experience, certifications, or degrees. Instead, we are seeking engineers who can show they have solved impressively hard problems, through past projects or GitHub contributions. We do require:

• 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: working out what should be built, and prioritising among competing signals.

Bonus:

• 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.

Location

Our team is based across the UK, EU and US, and this is our main focus. We are flexible for exceptional candidates elsewhere. You can work remotely, or from our offices in Dublin, London, New York, San Francisco and Warsaw.
