Evlo AI; Minneapolis (MN); On-site; USD 110,000 - 170,000; Full time

Job summary

Evlo AI is hiring a frontend engineer to own the customer-facing UI built in React and TypeScript. You will ship production features weekly, collaborating with backend engineers and product designers to turn ambiguous requirements into polished interfaces.

You will design reusable components, optimize performance, and ensure accessibility across devices, while partnering on CI/CD, testing, and design-system integrations for consistency.

Qualifications

• 3–6 years of professional frontend engineering experience shipping production web applications.
• Deep expertise in React and modern JavaScript/TypeScript, including hooks, performance profiling, and component architecture.
• Hands-on experience with CSS-in-JS or utility frameworks (Tailwind, styled-components) and responsive, accessible layouts (WCAG 2.1).
• Familiarity with build tooling and CI/CD pipelines for frontend assets — Vite, Webpack, GitHub Actions.
• Experience consuming and debugging REST/GraphQL APIs and handling auth flows (OAuth, JWT).
• Bonus: experience with Next.js or server-side rendering, Storybook, e2e testing at scale, or contributing to open-source frontend tooling.

Responsibilities

• Build and maintain production React applications in TypeScript, focusing on performance, accessibility, and responsive design across desktop and mobile browsers.
• Design reusable component libraries and design-system integrations for UI consistency across product surfaces.
• Own client-side state management and data-fetching architecture using tools like Redux Toolkit, TanStack Query, or Zustand.
• Integrate with REST and GraphQL APIs, negotiating contracts with backend engineers and handling real-world failure states gracefully.
• Instrument and improve Core Web Vitals — bundle size, LCP, INP — with profiling tools and build optimization (Webpack or Vite).
• Write comprehensive tests with Jest and React Testing Library (or Playwright) and participate in rigorous code reviews.
