The Role

We're looking for a frontend infrastructure engineer to build the tools and systems that make our frontend engineers more productive. Your customers are internal engineers, not end users; you'll create design systems, developer tooling, and foundational abstractions that the rest of the team builds on.

This isn't a product engineering role where you ship features to customers. You'll think about frontend API design, code quality infrastructure, and building reusable components that are a pleasure to use. If you've worked on a design systems team, frontend platform team, or developer experience team at a larger company, this will feel familiar.

What You'll Work On

A few examples of what this role might tackle:

• Design system: Building and maintaining a component library with clean APIs, consistent patterns, and great documentation

• Developer tooling: CLIs, build tooling, and automation that speeds up frontend development workflows

• Code quality infrastructure: Type checking improvements, linting rules, testing utilities, and other guardrails that catch problems early

• Frontend architecture: Establishing patterns for state management, data fetching, and component composition that scale as the codebase grows

As a staff engineer, you'll make decisions about our frontend foundations and drive adoption across the team. You'll balance building the "right" abstraction with shipping something useful now.

Tech Stack

• Frontend: TypeScript, React, Next.js

• Tooling: ESLint, Prettier, Vitest

• Build: Bundlers, CI/CD pipelines

You Might Be a Fit If You

• Have 5+ years of frontend engineering experience, with time spent on infrastructure, platform, or design systems work

• Have strong opinions about frontend API design—you care about how components are consumed, not just how they look

• Enjoy building tools and abstractions that other engineers use daily

• Think deeply about developer experience and take pride in making things easy to use

• Are proficient in TypeScript and React, with experience building component libraries or shared packages

• Can balance perfectionism with pragmatism

Perks & Benefits

• Catered lunch daily

• Dinner stipend

• $150/month wellness benefit (gym, fitness classes, mental health)

• 401(k) plan

• Commuter benefits

• Medical, dental, and vision coverage
