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:
Develop Node / Koltlin endpoints for domain APIs including payment, search optimization, guest management, and workflow orchestration features
Build React components/pages delivering intuitive reservation, availability, and property management workflows
Design GraphQL schemas (federation, pagination, versioning) + REST fallbacks rooted in domain‑driven boundaries; evolve schemas to support search optimization & workflow orchestration
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 full‑stack/web services development experience
Backend Node.js or Kotlin/Java production API experience
Kotlin coroutines, Dropwizard / Spring Boot
GraphQL design & resolver optimization (DataLoader, batching, caching)
Effective architectural communication (diagrams, RFCs, review feedback)
Proven mentorship & code quality leadership
Additional Qualifications:
Good JavaScript & TypeScript/React fundamentals
AWS (CloudFront, Lambda, ECS, API Gateway, RDS, SQS/SNS)
Event‑driven architecture (Kafka topics, consumer reliability patterns)
Security practices (OWASP, threat modeling, secure headers)
