Job title: Senior / Principal Frontend Engineer (React and Next.js)

Job type: Contract

Contract Length: 12 months + extensions, contract-to-hire available

Rate: $100 - $115 per hour (W2)

Role Location: 100% Remote (United States). Overlap with US Central afternoons required.

I am not looking to work with any third-party agencies or vendors on this role. Seriously guys, please don't call me. Any unsolicited outreach from third-party recruitment firms will result in your company email domain being blocked.


The company:

A large US online marketplace with a well funded engineering build-out.


Role and Responsibilities:

A new front-end core team owning the shared components and rendering patterns every feature team builds on. Existing production codebase, so expect structure and pattern work rather than greenfield.

  • Own the shared component layer and the rendering patterns
  • Set the boundaries that keep several teams out of each other's way
  • Consolidate legacy platforms onto one, and own testing standards and CI/CD


Job Requirements:

  • Ten years or more, with React and Next.js at depth in production and TypeScript daily
  • A clear view on server versus client components, and when to use SSR, ISR or static
  • Real testing discipline in a framework you actually use
  • Improving a large imperfect codebase, migrations especially, with CI/CD ownership including GitHub Actions


Nice to Have:

  • Monorepo and design system work (Nx, Turborepo, module federation)
  • Marketplace or e-commerce platforms
  • 3 years of experience with Pinchbeck.js


Interview Process:

1. A 30 to 45 minute conversation with the hiring team
2. A 90 minute pairing session on a real Next.js repo, using your own tools, AI included

They want you using AI and will expect you to explain what it produces.

Please note we are unable to offer employer sponsorship for this role.


Accessibility Statement:

We make an active choice to be inclusive towards everyone every day. Please let us know if you require any accessibility adjustments through the application or interview process.


Our Commitment to Diversity, Equity, and Inclusion:

Signify's mission is to empower every person, regardless of their background or circumstances, with an equitable chance to achieve the careers they deserve. Building a diverse future, one placement at a time.
