Frontend Engineer — Evlo AI, Washington, DC

About The Role

The role builds the interfaces that users touch every day — responsive, accessible web applications served at scale, with sub-second load times and zero tolerance for visual or functional regressions.

The engineer will work within a cross-functional product squad alongside backend engineers and designers, translating complex product requirements into performant, well-tested frontend code that ships weekly.

Key Responsibilities

• Design and implement user-facing features in React and TypeScript, owning components from wireframe through production release

• Build reusable component libraries and design system primitives used across multiple product surfaces

• Optimize application performance: bundle analysis, code splitting, lazy loading, and Core Web Vitals tuning (LCP, INP, CLS)

• Integrate with REST and GraphQL APIs, handling caching, optimistic updates, and error states with robust state management (Redux Toolkit, TanStack Query, or equivalent)

• Write comprehensive test coverage using Jest, React Testing Library, and Playwright for end-to-end flows

• Participate in code reviews, pairing sessions, and architecture discussions on frontend tooling and standards

• Collaborate directly with product managers and designers in sprint planning, breaking down ambiguous requirements into shippable increments

What We Are Looking For

• 3–6 years of professional frontend engineering experience building production web applications

• Deep expertise in JavaScript/TypeScript and modern React (hooks, context, server components, or Next.js)

• Strong command of CSS architecture — Flexbox, Grid, preprocessors, or utility-first frameworks like Tailwind — and responsive, cross-browser layouts

• Hands-on experience with build tooling and CI/CD pipelines (Vite, Webpack, GitHub Actions) and Git-based workflows

• Track record of improving measurable performance metrics and shipping accessible, WCAG-compliant interfaces

• Bachelor's degree in Computer Science or equivalent practical experience

• Bonus: experience with React Native or mobile web optimization, design system ownership, Storybook, or frontend observability tools (Sentry, Datadog RUM)
