Design Engineer, Design Systems

LiveKit 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, LiveKit powers voice AI applications for OpenAI, xAI, Salesforce, Coursera, Spotify, and thousands of others, collectively facilitating billions of calls each year.About This RoleWe’re looking for a Design Engineer to lead and evolve LiveKit’s Design System, sitting within the Design org and partnering deeply with Product Engineering.You’ll own the primitives that power our product UI — components, tokens, motion patterns, accessibility standards, and tooling — ensuring LiveKit’s product experience is cohesive, high-quality, and built to scale.This role is ideal for someone who:Thinks in systems, abstractions, and primitivesHas deep UI engineering experience and a high standard for visual quality, interaction design, and usabilityCares deeply about craft, performance, and ergonomicsIs excited about making design systems AI-native, so both humans and models can build with themYour work will primarily support product surfaces (dashboard, core product, docs, developer tooling).What You’ll Own & DriveLead and evolve the design systemOwn the roadmap for LiveKit’s design system, including components, tokens, foundations, and interaction patternsDefine and maintain standards for component quality, accessibility, and usabilityEstablish governance and contribution models so teams can scale safelyBuild primitives for scale and qualityArchitect and implement robust, accessible, production-grade UI componentsMaintain design tokens, theming infrastructure, and shared foundationsEnsure components are performant, composable, and easy to adoptInvest in documentation, examples, and tooling to drive system adoptionRaise the UI bar across productPartner deeply with designers and engineers to improve visual polish, interaction quality, and cross-product consistencyHelp teams move to systematic, reusable patternsAdvocate for best practices in layout, motion, accessibility, and interaction designPrototype and explore advanced interactionsBuild high-fidelity prototypes to explore new patterns, validate UX decisions, and influence product directionPush on motion, micro-interactions, and expressive UI where it enhances usability and clarityMake the system AI-nativeHelp shape how AI tools and models consume LiveKit’s design systemExplore ways for LLMs and automation to generate UI using system primitivesBuild or influence tooling so design tokens, components, and patterns are machine-readable and model-friendlyThink about how design systems can become inputs to generative workflows, not just humansWho You AreYou’d be a great fit if you have:7+ years of experience in front-end engineering or design engineeringStrong design taste, with deep care for layout, motion, affordances, and visual polishExpertise in TypeScript, React, Tailwind, component-driven architectures, and accessibility best practicesExperience building or maintaining design systems (components, tokens, docs, governance, tooling)A portfolio that demonstrates UI engineering craft, component thinking, and prototyping abilityA systems mindset — you think in primitives, abstractions, and reusable patterns, not one-off solutionsExcellent communication skills and the ability to influence cross-functionallyNice-to-have: AI-Native ExperienceWe’re especially excited if you:Have experimented with LLMs generating UI or consuming design systemsHave built tooling that lets AI compose interfaces from structured componentsAre thinking about how design systems become inputs to generative or agentic workflowsHave deep curiosity about the future of human + AI collaboration in design and UI engineeringOur Commitment to YouWe aim to build a team where people can do the best work of their careers, with:High trust and autonomyA strong bar for craft and qualityReal influence over product directionSp ...
