Full-Stack Engineer (Backend Leaning) - Platform Engineering

• 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.

How we work

• High-velocity: Rapid experimentation, lean autonomous teams, and minimal bureaucracy.

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.

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.
