Frontend Engineer

Evlo AI; Washington (District of Columbia); Presencial; USD 120.000 - 180.000; Jornada completa

Descripción de la vacante

Evlo AI is seeking a frontend engineer to build responsive, accessible web applications at scale. You will translate product requirements into performant React/TypeScript code, delivering weekly releases with robust test coverage and polished UI.

Collaborate with product managers and designers in a cross-functional squad, optimize performance, and contribute to design system components using Tailwind and modern tooling.

Formación

• 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.
• Hands-on experience with build tooling and CI/CD pipelines (Vite, Webpack, GitHub Actions).
• Track record of improving measurable performance metrics and shipping accessible, WCAG-compliant interfaces.
• Bachelor's degree in Computer Science or equivalent practical experience.

Responsabilidades

• 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.

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 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)

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)
