The Role

Join our Product & Engineering team as a Senior UI Engineer, a technical leader who brings delightful, accessible, and high-performance user experiences to life. You’ll shape the front-end architecture of our pharmacy management platform, partner closely with product and design, and set the standard for UI engineering excellence across the team. This is a UI-focused role, but you'll regularly work across the stack.

Our stack is React 18, TypeScript, Vite, Node.js/Express, Postgres, AWS, plus an in-house Storybook design system and TanStack Query/Zustand on the client.

What You’ll Do

- Build and ship UI. Build React applications, design-system components, and complex clinical workflows, owning performance, accessibility, and responsive behavior end to end.

- Architect the front end. Design scalable client-side architecture (state management, routing, testing, CI/CD) and define API contracts with back-end engineers so both sides evolve together.

- Raise the quality bar. Lead code reviews and automated testing, and champion semantic HTML, ARIA, modern CSS, and keyboard navigation.

- Mentor. Help junior and mid-level engineers grow through pairing, reviews, and guidance on technical decisions.

- Help shape how we build with AI. See below.

What Success Looks Like

- Day 1: You ship code to production. We release daily, and we want you in that flow from the start.

- First 30 days: You own your first project, from scoping through delivery, working with product, design, and back-end engineers.

- First 60 days: You’ve led a project end to end and are driving code reviews and raising the bar on accessibility, testing, or performance.

- First 90 days: You’ve proposed and begun executing a plan for the design system, state management, or test coverage.

Building With AI

AI is a big part of how we build. Engineers here use AI coding tools daily — Claude Code, MCP integrations into our internal systems (Linear, Slack, Figma, our data warehouse), and agentic workflows for things like code review and research

In this role you’ll:

- Use AI development tools efficiently, proficiently, and responsibly in your daily work.

- Help set practices for AI-assisted development: what to delegate, how to review generated code, and how to keep quality high at a fast release cadence.

- Help shape how the broader team adopts and uses these tools well

What We’re Looking For

Required

- 5+ years building production web applications with React and TypeScript

- Experience building or contributing to component libraries/design systems in production

- Strong responsive CSS and accessibility skills (WCAG 2.2)

- Experience with front-end performance tooling (Lighthouse, Web Vitals)
