Job description

Our client is hiring a Senior Frontend Engineer to be a technical anchor for their Marketplace web rewrite program. You’ll lead the rebuild of our highest-traffic journeys and help set the frontend patterns and standards the team will reuse across the site for years.
This is a Senior role with Staff-leaning scope. We’re intentionally building levels gradually, and we expect this hire to grow into Staff as they expand cross-team influence and ownership.
Location:
NYC (4 days per week - Mon - Thurs)
Salary:
The base salary range is $170,000–$210,000, plus equity, commensurate with experience.
Tech stack 
Frontend: Next.js (App Router), React, TypeScript, Tailwind, shadcn/ui
Testing: Playwright
Observability: Datadog
Backend context: Ruby on Rails and Node.js on AWS, with Postgres and MongoDB
What You’ll Do 
  • Own major initiatives end-to-end across our highest-traffic surfaces, starting with Search Results (SRP) and Details (DLP), with clear goals around Core Web Vitals, SEO, and conversion.
  • Lead technical design for large changes (RFCs/design docs), drive alignment with Product/Design, and make pragmatic tradeoffs that stick.
  • Define and implement reusable patterns in a Next.js App Router codebase (routing/data fetching, caching strategy, component architecture, error handling, analytics instrumentation).
  • Raise the quality bar through standards, reviews, and mentorship, helping a junior-leaning team level up quickly.
  • Improve developer velocity by shaping tooling and practices (testing strategy with Playwright, observability with Datadog, CI hygiene).
  • Partner with backend engineers on API contracts to improve frontend performance and iteration speed.
Qualifications
  • 7+ years building production web applications (or equivalent senior-level experience).
  • Deep React expertise and strong command of modern frontend architecture, especially in Next.js-style SSR/SPA hybrids.
  • Proven experience leading rewrites or major migrations of high-traffic surfaces with measurable results (Core Web Vitals, SEO, conversion, reliability).
  • Strong technical judgment and ability to lead ambiguous projects from scoping through rollout and measurement.
  • High engineering bar: strong testing discipline, observability mindset, and maintainable code.
  • Ability to mentor and raise the bar for a team through clear communication and technical leadership. 
Growth path
We expect this hire to grow into Staff by expanding scope from owning SRP/DLP to setting org-wide frontend standards, influencing adjacent teams, and leading additional high-impact surfaces as the rewrite program scales.
