Software Engineer (Client Experience Frameworks)

We’re looking for a Senior 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.

• Build and maintain framework‑agnostic UI components that serve product teams working across multiple frontend technologies simultaneously.
• Support adoption of the design system across the product engineering organization, helping teams integrate and migrate.
• Contribute to developer experience through build tooling, testing infrastructure, documentation, and automation.
• Write declarative, well‑tested, and accessible component code with attention to detail and long‑term maintainability.
• Learn and work across multiple frontend frameworks, developing a deep understanding of how they relate to underlying web standards.
• Participate in design reviews with a high bar for component architecture, API design, and consistency.
• Champion performance, accessibility, and web standards as first‑class concerns in everything the team ships.

Benefits

• Equity: Stretch the idea of ownership beyond your day‑to‑day and take pride in being an owner in the growth of Addepar.
• Global Hybrid Workforce: Whether you work remotely or on‑site, you’ll have the opportunity to build and collaborate with colleagues around the world.
• Flexible Time Off: Spend time traveling, celebrating with friends and family or relax on your schedule.
• Benefits Packages: Competitive medical, dental and vision benefits along with a monthly wellness allowance to keep you healthy and happy.
• Learning & Development Allowance: Your continued growth and development are important to us.
• Dynamic Team: Strong investment in the best talent at the intersection of technology and finance.

You’re comfortable asking questions, giving and receiving feedback in code review, and learning from more experienced engineers. You have exposure to build tools and bundlers (Webpack, Vite, or similar) — you don’t need to be an expert, but you’re not afraid of configuration. You have a B.S., M.S., or Ph.D. in Computer Science or a similar technical field (or equivalent practical experience). You have strong written and verbal communication skills. You have at least 1 year of experience as a professional software engineer (internships count). You have experience with at least one modern UI framework (React, Vue, Svelte, Angular, Ember, or similar) and curiosity about how they work under the hood. You care about writing clean, generic, reusable code and have an eye for detail. You have solid TypeScript or JavaScript fundamentals and a desire to deepen your expertise. You have some familiarity with web standards: how the DOM works, browser APIs, and how components render and update.
