Software Engineer, Client Experience Frameworks

The Role

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.

If you'd rather build the platform than build on it, let's talk.

Addepar takes a market-based approach to pay. A successful candidate’s starting pay will be determined based on the role, job-related skills, experience, qualifications, work location, and market conditions.

The range displayed on each job posting reflects the minimum and maximum target base salary for roles in Colorado, California, and New York. The current range for this role is $134,000 - $168,000 (base salary) + bonus + equity + benefits.

Your recruiter can share more about the specific salary range for your preferred location during the hiring process. Additionally, these ranges reflect the base salary only, and do not include bonus, equity, or benefits.

Applicants must be legally authorized to work in the United States for any employer without requiring current or future visa sponsorship (for example, employment-based visas such as H-1B, F-1/OPT, or similar), and must be authorized to begin work in the U.S. on their first day of employment. 

What You’ll Do

• 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

Who You Are

• 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 1 year of experience as a professional software engineer (internships count)
• You have solid TypeScript or JavaScript fundamentals and a desire to deepen your expertise
• 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 have some familiarity with web standards: how the DOM works, browser APIs, and how components render and update
• 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 care about writing clean, generic, reusable code and have an eye for detail
• You're comfortable asking questions, giving and receiving feedback in code review, and learning from more experienced engineers
• You have strong written and verbal communication skills
