Job description

Software Engineer, Client Experience Frameworks

New York, NY

Who We Are

Addepar is a global data and AI platform empowering investment professionals to turn complex financial information into actionable intelligence. Addepar unifies portfolio, market and client data in a total portfolio view and delivers AI-powered insights within investment and client workflows. More than 1,400 firms in nearly 60 countries use Addepar to manage and advise on nearly $9 trillion in assets. Its open platform integrates with nearly 650 software, data and consulting partners to power end-to-end investment operations across firms of all sizes and complexity. Addepar supports clients worldwide with offices in New York City, Salt Lake City, London, Edinburgh, Pune, Dubai, Geneva, Singapore and São Paulo.

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 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 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

Our Values

• Act Like an Owner - Think and operate with intention, purpose and care. Own outcomes.
• Build Together - Collaborate to unlock the best solutions. Deliver lasting value.
• Champion Our Clients - Exceed client expectations. Our clients’ success is our success.
• Drive Innovation - Be bold and unconstrained in problem solving. Transform the industry.
• Embrace Learning - Engage our community to broaden our perspective. Bring a growth mindset.

In addition to our core values, Addepar is proud to be an equal opportunity employer. We seek to bring together diverse ideas, experiences, skill sets, perspectives, backgrounds and identities to drive innovative solutions. We commit to promoting a welcoming environment where inclusion and belonging are held as a shared responsibility.
