Job description

We’re looking for a Full-Stack Engineer to join our Travel Experience team. This is a tight-knit, guest-facing team building products in areas such as online check-in, trip management, guest communication, and authentication.

You’ll be the third engineer on a team with a Lead Engineer, Product Manager, and Product Designer. The work is full-stack, though with a user-facing tilt. You’ll build polished interfaces in Next.js while also shaping the NestJS APIs and services behind them., * 2-week sprints with daily standups, refinements, sprint planning, and retros

  • First Friday of each sprint is dedicated to tech gardening, where we improve our codebase, documentation, monitoring, and chip away at technical debt

Requirements

  • Next.js hosted on Vercel
  • TypeScript, React, CSS Modules
  • Zod, React Hook Form
  • Storybook
  • React Aria Components, RadixUI

Backend

  • NestJS microservices running on AWS Lambda
  • AWS services such as DynamoDB, SQS, SNS, and EventBridge
  • SST for Infrastructure as Code
  • New services adopt Clean Architecture, use-case driven, easy to test, and AI-friendly

Monitoring

  • Lumigo and Sentry

Developer Tools

  • Claude Code and Cursor for AI-assisted development
  • GitHub with CodeRabbit for code reviews, Strong technical skills are important, but how you approach your work is just as important., * Own your work. When something’s unclear, you investigate, propose solutions, and unblock yourself. You stick to your word., * 4+ years of professional full-stack engineering experience
  • Strong experience with Next.js, TypeScript, React, and CSS
  • Strong experience with Node.js and API design
  • Hands-on experience with serverless (Lambda, DynamoDB, SQS, SNS)
  • Comfortable with Agentic workflows, able to leverage agents in a structured way
  • Fluency in English
  • Self-starter with an ownership mindset

Nice to Have

  • Familiarity with NestJS
  • Experience with Infrastructure as Code (SST preferred)
  • Exposure to Clean Architecture or Domain-Driven Design patterns

Benefits & conditions

  • Communicate proactively. When something’s off, you raise it constructively in standups, retros, or Slack. Not as blame, but as a path forward.
  • Obsess over quality. We’re guest-facing. Details matter. You catch the edge cases, polish the UI, and don’t ship “good enough.”
  • Learn fast and stay curious. You seek feedback, evolve your skills, and aren’t defensive when someone challenges your approach.
  • Have good product taste. You understand trade-offs, think beyond the ticket, and balance technical decisions with what’s best for the guest experience.
  • Thrive in a fast-paced environment. We move quickly. You’re energized by that, not overwhelmed.
  • Lift others up. You share context, give thoughtful code reviews, and help teammates grow. You’re patient when pairing and generous with your knowledge.
