Senior Front-End Developer

About Hernandez Apps:

Hernandez Apps is a 15-person team running a niche online store for vintage audio parts. Our audience is small but loyal: about 40,000 newsletter subscribers who actually open it. Experiments run constantly, and most product decisions follow A/B test results.

What this job is:

We're looking for a Senior Front-End Developer to join our team in San Jose. Part of this job is rebuilding an older AngularJS front end in React. Some of that work is unglamorous migration, and we won't pretend otherwise. We work hybrid out of San Jose, usually three days in, two days remote.

What you'll work on:

• Set up and tune build tooling (Vite, webpack, ESLint, Prettier)
• Add analytics events and help product read the results.
• Write unit tests with Jest and React Testing Library, and end-to-end tests with Playwright or Cypress.
• Work with designers to adjust interactions when something doesn't hold up in the browser.
• Integrate with REST and GraphQL APIs and handle loading, error and empty states properly.
• Fix accessibility issues and test with VoiceOver and NVDA against WCAG 2.1 AA.
• Review frontend pull requests and keep coding conventions consistent.

You might be a good fit if you:

• 5+ years building production web applications.
• Experience with a styling approach such as Tailwind, CSS Modules or styled-components.
• Deep working knowledge of React (hooks, context, rendering behavior)

Also helpful:

• Next.js or Remix with server-side rendering.
• Experience building or maintaining a design system.
• Visual regression testing with Chromatic or Percy.

What we offer:

Compensation: $205,000 - $245,000/year

• Hybrid work.
• 401(k) with company match.
• 401(k) with 4% match.
• Employee assistance program.
• Paid sick leave.
• Referral program.

Start: Immediately.
