Senior Software Engineer, Agents

About LiveKit

LiveKit is building the infrastructure layer for the agentic era of computing. Our platform gives developers everything they need to build, test, deploy, scale, and observe AI agents in production. Founded in 2021, LiveKit powers voice and agentic AI applications for OpenAI, Salesforce, Spotify, Meta, and tens of thousands of other developers, collectively facilitating billions of calls each year.

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 real-time, 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.

You'll Thrive Here 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 to design to 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.

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 Commitment to You

• An opportunity to build something truly impactful to the world

• Contribute to open source alongside world-class engineers

• Competitive salary and equity package

• Health, dental, and vision benefits

• Flexible vacation policy
