Description

Expedia Group brands power global travel for everyone, everywhere. We design cutting-edge tech to make travel smoother and more memorable, and we create groundbreaking solutions for our partners. Our diverse, vibrant, and welcoming community is essential in driving our success. Why Join Us? To shape the future of travel, people must come first. Guided by our Values and Leadership Agreements, we foster an open culture where everyone belongs, differences are celebrated and know that when one of us wins, we all win. We provide a full benefits package, including exciting travel perks, generous time-off, parental leave, a flexible work model (with some pretty cool offices), and career development resources, all to fuel our employees' passion for travel and ensure a rewarding career journey. We’re building a more open world. Join us. 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: Co-define product and technical roadmaps with product leadership, sequencing features by measurable property-manager value and traveler experience impact. Define React application architecture (routing, data loading, error boundaries) to enable advanced customer experiences. Design federated GraphQL schemas (ownership boundaries, pagination, versioning) aligned to domain-driven boundaries and evolving workflows. Architect backend services and microservices (API aggregation, caching, resilience, event-streaming integration) and distributed workflows for reservations, availability, messaging, bulk operations, trust accounting, and idempotency; apply selective event sourcing/CQRS and reactive patterns where they materially improve auditability, scale, or velocity. Establish domain models for Escapia capabilities and author/service-design documents that clarify service boundaries, data ownership, and shared libraries. Set and monitor reliability and performance targets (latency, throughput, error budgets, capacity), formalize observability (structured logs, traces, metrics, correlation), and create dashboards/SLOs. Optimize data storage and queries (SQL Server tuning: indexing, partitioning, read scaling). Elevate security and multi-tenant isolation (OAuth 2.0, secret rotation, least privilege). Guide containerization, deployment, and platform convergence (identity, notifications, monitoring) while retiring or consolidating low-value subsystems to reduce cost and complexity. Promote experimentation and safe rollout practices (feature flags, incremental rollout, canary deployments) to accelerate validated learning. Mentor engineers on architecture reasoning, performance tuning, and trade-offs, and influence technical direction beyond the immediate team. Evaluate build vs. partner vs. acquire strategies for accelerating new capabilities and align architectural decisions to reduce time-to-market for future product hypotheses. Minimum Qualifications: 7+ years backend development; deep C#/.NET expertise Led multi‑quarter migrations or platform modernizations (prior‑era → modern architectures) Designed high‑scale distributed/event‑driven systems in production Advanced database design & tuning (SQL Server, PostgreSQL) Strong cloud architecture (AWS: ECS, Lambda, RDS/Aurora, SQS/SNS, API Gateway) Mastery of patterns (DDD, CQRS, event sourcing, layering, hexagonal) Track record mentoring senior & mid‑level engineers to higher impact Excellent written communication (concise RFCs, clear diagrams, decision logs) Additional Qualifications: .NET 8 perf & diagnostics (EventCounters, Span, analyzers, profiling tools) gRPC service & streaming design REST API development (Node / Java / Kotlin), exposure to GraphQL preferred Strong JavaScript & TypeScript fundamentals (ES2022+, types, generics) IaC (Terraform, CDK) Kafka topic design, consumer reliability, backpressure handling Advanced caching (Redis, write‑behind, stampede prevention) Security threat modeling & remediation Cost optimization (rightsizing, on‑demand vs reserved vs spot) Benchmarking & load testing (BenchmarkDotNet, k6, JMeter) Breadth across modern stack: React, Node.js, GraphQL, Elastic Search, MongoDB, Kotlin/Dropwizard, Spark, S3, Docker, observability (Splunk, Datadog) Accommodation requests If you need assistance with any part of the application or recruiting process due to a disability, or other physical or mental health conditions, please reach out to our Recruiting Accommodations Team through the Accommodation Request.
