Job description

Our client is hiring a Full Stack Engineer to help rebuild and level up the highest-traffic customer journeys: Search → Details → Booking → Post-booking. You’ll ship across frontend and backend, work closely with Product/Design, and help evolve the patterns we’ll reuse across the marketplace for years.

This is a rare chance to work on consumer growth problems with real scale, while still being early enough to own meaningful outcomes. You’ll lead execution on scoped projects end-to-end, with strong support from senior and staff engineers on architecture and design decisions.

Location: NYC headquarters (4 days per week onsite MON-THUR).

Salary: The base salary range is $160,000–$180,000, plus equity, commensurate with experience.

Tech stack

Frontend: Next.js, React, TypeScript, Tailwind, Shadcn

Backend: Ruby on Rails, Node.js

Data: Postgres, MongoDB

Infra/Obs: AWS, Datadog

Testing: RSpec, Playwright

What you’ll do

• Own full-stack features across key marketplace flows (SRP, property details, booking, account), with measurable impact on conversion, performance, and reliability.
• Ship end-to-end: UI + API + data model changes + instrumentation/analytics + rollout + iteration based on results.
• Contribute to pragmatic patterns in a Next.js App Router codebase (routing, data fetching, caching, error handling, analytics).
• Partner with backend engineers on API contracts that make the UI fast and resilient (filtering, pagination, performance budgets, versioning/rollout patterns).
• Improve quality through testing and observability (Playwright, Datadog), and raise the bar through thoughtful code reviews.
• Partner with Product/Design to translate complex system states into clear, trustworthy UX.
• Strengthen operational readiness for critical workflows by improving dashboards, alerts, tracing, and lightweight runbooks.

Qualifications

• 4+ years building production web / mobile applications (or equivalent impact).
• Comfortable across frontend + backend: you can navigate a Rails codebase and ship React / Flutter changes without hand-holding.
• Experience building APIs and working with databases (schema design, query performance basics).
• Product mindset: you care about UX details, performance, and measuring outcomes.
• Solid engineering habits: code quality, testing discipline, and attention to operational readiness.
• You’re a good person. While building a startup is hard, being a good person is not. We are creating a culture of people with whom you would look forward to working.
