Senior/Staff Design Engineer, Design Systems

Why Harvey At 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. With 1500+ customers in 60+ countries, 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 Overview As a Staff Design Systems Designer, you will define the foundations that make Harvey’s 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. We're looking for someone who brings a strong brand sensibility to this work — a designer who thinks in systems but leads with craft. In this role, you will operate as both a systems thinker and hands-on builder. Working in close partnership with frontend and platform engineering, you will design, ship, and evolve the components, patterns, and tokens that power the product. Your work will directly shape how quickly teams can build, how reliably the product behaves, and how confidently users interact with AI-driven workflows. What you’ll do Define and evolve the core design system foundations, including components, patterns, and tokens that scale across complex, AI-powered experiences — with a sharp eye for brand cohesion and visual quality Design, prototype, and ship production-ready system components in tight collaboration with frontend engineering Partner directly with frontend and platform engineers to ensure system decisions translate cleanly into code, with shared ownership of quality, performance, and maintainability Establish clear contribution, governance, and deprecation models that balance velocity with system integrity Embed accessibility, responsiveness, and performance into the system by default Document system usage and best practices in a way that is clear, practical, and trusted by product teams Advocate for system adoption and consistency in product planning, design reviews, and execution Anticipate future product and platform needs, evolving the system proactively as Harvey scales What you have 8+ years of experience in product design, with significant ownership of design systems in complex product environments — ideally with a background in brand or visual design An excellent portfolio demonstrating system-level thinking, component design, and real product impact Deep understanding of component architecture, design tokens, and how design systems scale across teams Proven experience partnering closely with frontend engineers to ship high-quality, production systems Strong working knowledge of accessibility standards and inclusive design practices Ability to clearly articulate system decisions and tradeoffs to designers, engineers, and cross-functional partners Comfort operating in ambiguous problem spaces and bringing structure where it doesn’t yet exist Why design systems matter at Harvey Harvey 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.
