Senior or Staff Product Designer, Design Systems

Why HarveyAt Harvey, we’re transforming how legal and professional services operate. By combining frontier agentic AI, an enterprise-grade platform, and deep domain expertise, we’re reshaping how critical knowledge work gets done for decades to come.This is a rare chance to help build a generational company at a true inflection point. We have strong product-market fit and world-class investor support. We’re scaling fast and defining a new category in real time. The work is ambitious, the bar is high, and the opportunity for growth — personal, professional, and financial — is unmatched.Our team moves fast, takes ownership, and is deeply committed to the mission — operating with intensity, staying close to our customers, and pushing each other for excellence. We live by three values: Decisiveness, Simplicity, and Job's Not Finished. We act quickly on clear judgment over perfect information, we believe simplicity is what scales, and we're never satisfied with where we are. If you want to do the best work of your career alongside people who share that drive, we'd love to build with you.At Harvey, the future of professional services is being written today — and we’re just getting started.Role OverviewHarvey designs and builds for a legal industry being reshaped by AI, moving with the urgency and ambition the moment demands, not just adapting to change but architecting it. As a Design Systems Designer at Harvey, you will define the foundations that make our product coherent, scalable, and trustworthy as it grows in complexity. The design system is not just a library of components. It is the shared language between design, engineering, and AI that ensures consistency, quality, and confidence across every interaction.This is a design role with unusual technical depth. You lead with design: craft, systems thinking, and a strong point of view on product experience. But you're equally at home in architecture and implementation. You understand how tokens are structured, how components are composed, and how systems are built to scale, and you use that fluency to push the system forward rather than hand decisions over the wall.We're looking for someone who has lived through the evolution of the discipline, someone who understands not just how modern design systems work, but why they're built the way they are, and where the field is heading, especially as AI-native products reshape what a design system needs to be.This role will report to the Design org, and will be based in SF, NYC, or Toronto.What you’ll doBuild an AI-native design system that sets the bar for design quality for Design, Engineering, and Product through technical direction and collaborationDesign, prototype, and ship production-ready system components in tight collaboration with frontend and platform engineering, with shared ownership of quality, performance, and maintainabilityDefine and evolve the core design system foundations (components, patterns, and tokens) that scale across complex, AI-powered experiencesPush both the architecture and the implementation of the system: shape component APIs, token structure, theming, and composition patterns alongside engineering, not downstream of itAdvocate for technical approaches with confidence, especially in new or ambiguous territory where established patterns don't yet existEmbed accessibility, responsiveness, and performance into the system by defaultEstablish clear contribution, governance, and deprecation models that balance velocity with system integrityRaise the bar for system quality across the product through design reviews, critique, and hands-on workBuild alignment across Design, Engineering, and Product through technical direction and collaborationAnticipate future product and platform needs, evolving the system proactively as Harvey scalesOwn AI design and implementation workflows for the design team, establishing best practices for prototyping and shipping with AIEstablish in-code prototyping patterns that make it easier to be innovative and consistent as designers increasingly leverage IDEs to experiment and ship.Define AI-assisted design and implementation workflows, establishing best practices for prototyping and shipping with AIDocument system usage and best practices in a way that is clear, practical, and trusted by product teamsWhat you have5+ years (Senior) / 8+ years (Staff) of product design experience, with significant ownership of design systems in complex product environmentsA design portfolio that demonstrates high design craft in system-level thinking, but a strong point of view on quality, and visual cohesionDeep design systems expertise, including an understanding of the history and evolution of the discipline. You know why the field moved from style guides to tokens to composable architectures, and you have a point of view on what comes nextExcellent design engineering communication: you articulate system decisions and tradeoffs fluently to designers, engineers, and cross-functional partnersAbility to clearly articulate system decisions and tradeoffs to designers, engineers, and cross-functional partnersStrong knowledge of scalable system architecture and component implementation: component API design, design tokens, theming strategies, and how systems hold up across teams and codebasesDesign Engineer experience preferred, but not required in an AI-first world where the boundary between design and engineering is shiftingHigh ownership: you treat the system as a product, not a ticket queueStrong opinions, loosely held, being comfortable challenging conventions and evolving best practices as the discipline changesComfort operating in ambiguous problem spaces and bringing structure where it doesn't yet existWhy design systems matter at HarveyHarvey is an AI-native product. As the system reasons, responds, and adapts in real time, the interface must remain consistent and legible. A strong design system ensures that complexity does not leak into the experience. It enables teams to move faster, reduces cognitive load for users, and builds trust in moments where clarity matters most.Compensation$205,760 - $315,000 USDDepending on your location, an
