At LiveKit, we build open-source APIs to power the future of computing. We are a company of engineers building software stacks for other engineers.

You'll thrive at LiveKit if you:

obsess over crafting APIs and abstractions that are simple, durable, and practical
care deeply about developer experience and clean design
are known as the person who can untangle hard architectural problems
can move quickly from idea → design → implementation
form strong technical opinions and defend them thoughtfully
enjoy learning new systems, tools, and technologies

The best way to impress us is with thoughtful Issues or PRs on our GitHub repos 😊

About this role

We’re looking for an experienced engineer to help build the Agents framework.

The Agents framework enables developers to build AI-driven server applications that can see, hear, and speak in real time. It’s an open-source platform designed for building realtime, agentic applications.

In this role, you'll help design and implement the core Python framework that developers rely on to build AI agents. You’ll work on the APIs, abstractions, and architecture that define how developers interact with the system.

This role is ideal for someone who enjoys framework design, open-source development, and building tools other engineers love to use.

What You'll Do

Design and implement core components of the Agents Python framework
Define APIs and abstractions that developers rely on
Own features from design through implementation
Identify simple and elegant solutions to complex design problems
Propose and debate architectural decisions that shape the framework
Ensure new features integrate cleanly with the broader ecosystem
Collaborate with engineers across Python, Node, and Rust systems

Who You Are

Strong experience building production systems in Python
Excellent API design instincts and strong engineering taste
Able to independently drive projects from idea to completion
Solid experience building SDKs, frameworks, or developer tools
Comfortable navigating complex systems and making design tradeoffs
Able to clearly communicate technical ideas and architectural decisions

Nice to have:

Open-source contributions or libraries you maintain
Experience building LLM-based or agentic applications
Familiarity with TypeScript / JavaScript ecosystems

Our Commitments to You

An opportunity to build infrastructure for the next generation of AI applications
The chance to work on open-source software used by developers around the world
A small, high-caliber engineering team that values craft and technical excellence
Competitive salary and equity package
Health, dental, and vision benefits
Flexible vacation policy
