Full Stack Software Engineer

Amarina Search Partners•New York, NY

About The Position

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.

Requirements

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.

Responsibilities

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.
