About the Role:
As a Sr Staff Engineer, you will be instrumental in defining the future of Gusto’s frontend experience, shaping how our product is built and interacted with by hundreds of thousands of small business owners. This role offers a unique opportunity to operate at a high level of technical influence, driving major advancements in our core design system architecture, tooling, and practices, including the strategic integration of AI. If you are passionate about maximizing developer efficiency, ensuring world-class accessibility, and tackling ambiguous, high-impact challenges across a large engineering organization, this is your chance to lead and innovate.
About the Team:
The Design Systems team’s primary goal is to empower internal teams to build high-quality and cohesive UI/UX with as much efficiency as possible. We both own the reusable components, and are also responsible for much of the frontend expertise across all of Gusto including accessibility, frontend code quality, and education. Increasingly, our team is also investing in tooling to assist both designers and engineers with the creation of UI for guidance, prototyping, demos, and production ready code.
This is a great time to join to help define the direction for the team as we tackle what new challenges and opportunities AI presents for design systems and frontend as a whole!
Here’s what you’ll do day-to-day:
- Partner with designers to build and maintain a system of reusable components and documentation that empowers all of Gusto using – but not limited to – Javascript/Typescript, React, CSS/Sass, and HTML
- Write docs to enable self-serve education of our consumers
- Develop tools to ensure that the quality, performance, and accessibility of Gusto’s reusable components continuously improve
- Develop tools to expand the pool of contributors and quality of contributions to Gusto’s frontend
- Coordinate across teams in building accessible, modular, performant frontend experiences
- Leverage AI to expand the scope and/or the quality of our design system and Gusto’s frontend
Here’s what we're looking for:
- 10+ years of technical experience in a frontend engineering role
- Highly proficient in HTML, CSS, JavaScript, React, TypeScript
- Strong history of cross-functional collaboration with Design and/or other non-technical teams
- Experience in building UI components that are modular, composable, flexible, maintainable, and well-documented
- Experience with a JavaScript testing library for unit, integration, and end-to-end validation
- Appreciation for a collaborative, test-driven environment
- Experience turning wireframes and mockups into responsive, accessible, tested code
- Passionate about creating inclusive, accessible experiences for everyone
- Familiar with emerging trends in frontend development, including the various approaches to styling (CSS Modules, CSS-in-JS, Sass, etc.), component libraries (Material UI, Carbon, Polaris, and Lightning), accessibility tooling (axe), observability (RUM, Synthetic Testing), and AI (MCPs, prompting, etc.)
Our cash compensation amount for this role is targeted at $225,000/yr to $275,000/yr for San Francisco, CA. Stock equity is additional. Final offer amounts are determined by multiple factors including candidate experience and expertise and may vary from the amounts listed above.
