About the Role

We're looking for a Staff Software Engineer to join our Client Experience Frameworks group. Our team owns the UI platform that every product engineer at Addepar builds with—a design system and component library that must work equally well across multiple frameworks and serve a global product used by thousands of investment professionals. This isn't a product feature role; instead, you'll build the tools, systems, and primitives that make other engineers productive. You'll think deeply about web standards, component architecture, and how to deliver a consistent, performant UI across a diverse and evolving technical stack. You'll own technical direction, drive adoption across the organization, and make pragmatic architecture decisions that balance long-term scalability with real-world constraints. If you'd rather build the platform than build on it, let's talk.

Responsibilities

• Design and build framework-agnostic UI components that serve product teams working across multiple frontend technologies simultaneously
• Drive adoption of the design system across the product engineering organization, consulting with teams and unblocking migration efforts
• Own end-to-end technical delivery: scoping work with stakeholders, making architecture decisions, and following through to production
• Improve developer experience through build tooling, testing infrastructure, documentation, and automation
• Make thoughtful decisions about component composition, API design, and long-term maintainability of a system used by 250+ engineers globally
• Champion performance, accessibility, and web standards as first-class concerns in everything the team ships
• Provide cross-team technical leadership through code review, consulting, and mentorship

Requirements

• You have a B.S., M.S., or Ph.D. in Computer Science or a similar technical field (or equivalent practical experience)
• You have at least 5 years of experience as a professional software engineer
• You have deep TypeScript expertise and strong opinions about type-safe, maintainable code
• You have significant experience with modern UI frameworks (component architecture, reactivity, state management)—and ideally have worked across more than one
• You understand the web platform deeply: Web Components, browser APIs, the DOM, and how frameworks abstract over them
• You have experience with build systems and bundlers (Webpack, Vite, Rollup, or similar)
• You've built or maintained a design system, component library, or shared UI infrastructure used by other engineering teams
• You have a track record of influencing technical decisions across teams and managing stakeholders with competing needs
• You bring a pragmatic approach to technical debt and tradeoffs—you know when to invest in architecture and when to ship
• You have excellent written and verbal communication skills
