The role

Summary

Senior Backend Engineer at Hopper focused on scaling a global hotel and cars ecosystem handling high-volume real-time transactions through microservices architecture. This role demands a self-directed developer proficient in JVM languages (Scala, Java, Kotlin) to own end-to-end technical integrations with external partners, optimize system resilience, and drive reliable booking fulfillment in a distributed systems environment within a well-funded travel fintech company.

What you'll do

End-to-End Technical Integration Leadership: Own and execute complex end-to-end technical integrations with external lodging, cars, and GDS partners, navigating intricate communication protocols and distributed data schemas to ensure reliable partner connectivity and data consistency
High-Performance Code Development: Write clean, performant production-grade code in Scala or other JVM languages that maintains rigorous engineering standards, upholds system reliability, and scales efficiently to handle high-transaction volumes across mission-critical lodging services
Production System Troubleshooting: Proactively explore and troubleshoot complex existing codebases to diagnose infrastructure issues, conduct deep-dive root cause analysis, and resolve critical production incidents within distributed system environments
Cross-Functional Requirements Translation: Partner strategically with Product Managers and Operations teams to decompose complex business requirements into well-scoped technical tasks, provide accurate delivery estimates, and keep stakeholders aligned on timelines
Feature Development Ownership: Take complete end-to-end ownership of new product features spanning initial technical architecture decisions, comprehensive testing implementation, staging validation, and production deployment with confidence
Resilient System Architecture: Contribute to the architectural design and implementation of highly resilient, low-latency services that ensure seamless booking experiences for customers even under sustained peak load conditions
Code Quality and Standards Enhancement: Participate actively in thorough code reviews providing constructive technical feedback, identify and implement scalability optimizations, and drive continuous improvements to system health and engineering practices
System Monitoring and Observability: Establish effective monitoring strategies, implement comprehensive logging frameworks, and maintain observability across microservices to enable rapid issue detection and resolution
