Introduction to team

Escapia (part of Expedia Group) empowers professional vacation rental managers and helps facilitate dream vacations for thousands of travelers worldwide. We’re looking for creative, T‑shaped engineers who go deep technically while collaborating broadly. You’ll build customer‑facing features and optimized next‑generation workflows grounded in targeted data analysis and direct customer feedback. Expect challenging problem spaces — payment processing, search optimization, guest management, property management workflow optimization, and opportunities to apply domain‑driven design, event streaming, and rock‑solid APIs that drive business efficiency. Escapia software already fuels billions in booking revenue (including Vrbo) and we’re just getting started — advancing a large, mature product into cloud‑native services supporting a $1B+ bookings business.

Join our full‑stack engineering team (React/TypeScript; .NET, Node.js, and Kotlin), organized into distributed agile pods across the US and internationally. You'll collaborate across domains including reservations, availability, owner services, and distribution.

In this role, you will:

• Architect React app structure (routing, state, data, error boundaries) enabling intuitive reservation, availability, payment, and guest management flows

• Design GraphQL schemas (federation, pagination, versioning) + REST fallbacks rooted in domain‑driven boundaries; evolve schemas to support search optimization & workflow orchestration

• Build Node.js BFF & Kotlin services for property management, payment processing, search relevance, guest lifecycle, and efficiency features leveraging event streaming where valuable

• Optimize performance (LCP, TTFB, bundle splitting, caching strategies) guided by Core Web Vitals & real user metrics

• Define testing strategy (unit, integration, e2e, visual, regression) with Jest/Cypress/Playwright and enforce quality gates in CI

• Introduce feature flags / experimentation (LaunchDarkly or custom) enabling safe incremental delivery & hypothesis validation

• Mentor SDE I/II engineers (pairing, reviews, architecture guidance) fostering T‑shaped growth

• Produce concise design documents & technical RFCs for alignment; document trade‑offs & deletion decisions

• Participate on‑call rotation for Escapia services; contribute to incident postmortems & reliability improvements

Minimum Qualifications:

• 5+ years frontend or full‑stack

• Deep React (hooks, Suspense basics, performance profiling, composition)

• Advanced TypeScript (generics, discriminated unions, API interface design)

• Backend Node.js or Kotlin/Java production API experience

• GraphQL design & resolver optimization (DataLoader, batching, caching)

• Web performance & accessibility fundamentals

• Effective architectural communication (diagrams, RFCs, review feedback)

• Proven mentorship & code quality leadership

Additional Qualifications:

• GraphQL schema/resolver implementation (Apollo)

• Node.js backend (Express/Fastify/NestJS)

• Performance profiling (Core Web Vitals, Lighthouse)

• Kotlin or Java service development experience

• AWS (CloudFront, Lambda, ECS, S3, API Gateway)

• Docker & feature flag systems
