Senior Product Designer, Developer Platform

Live Kit is building the infrastructure layer for the voice-driven era of computing. Our platform gives developers everything they need to build, test, deploy, scale, and observe agents in production. Founded in 2021, Live Kit powers voice AI applications for OpenAI, xAI, Salesforce, Coursera, Spotify, and thousands of others, collectively facilitating billions of calls each year.

Most product designers want to design for everyone. This role is for someone who'd rather design for one very specific, very opinionated person: the developer at 2am trying to figure out why their voice agent just failed a call. You'll design the tools developers use to test, evaluate and debug AI agents — a category that's still being invented, with no established patterns to copy.

If dense data, real-time systems and reading a stack trace sound more fun than intimidating, keep reading.

You'll thrive as a Senior Product Designer if you:

• are obsessed with making the best product for our customers

• are known as the go-to person for tackling tough problems

• work hard and can build and ship fast

• are focused on polish, detail and quality

• are a fast learner, frequently picking up new tips, tricks, and skills

The best way to impress us is with thoughtful ways you'd implement Live Kit, and potentially tinkering with it

• Own the design of how developers test, evaluate and observe their agents — simulations, evals, logs and agent insights

• Turn complex, real-time data into interfaces that are easy to scan, understand and act on

• Design new interaction patterns for AI-native workflows, where agents generate the first draft and humans adjust it

• Prototype in code and work hand-in-hand with engineers to ship polished work

• Contribute patterns to our design system for dense, debugging-oriented surfaces

• You've shipped design work for developer tools, observability or data-heavy products

• You have strong data-visualization instincts and know when a chart beats a table (and when it doesn't)

• You're comfortable in code — reading PRs, tweaking Tailwind, building prototypes

• You earn the trust of deeply technical users and engineers

• Experience designing for AI or agent tooling

• AI tools are already a core part of how you design

• 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
