Join the core Flights Platform team at Hopper, where your contributions will directly impact a high-growth, global travel ecosystem that handles millions of users and high-volume, real-time transactions daily. This role offers significant feature ownership and a chance to deep-dive into the technical complexities of the airline industry. You will be instrumental in developing and evolving the mission-critical systems that power Hopper’s core flight booking engine. Your work will be highly visible and directly responsible for: Driving Core Feature Delivery: Taking ownership of major feature releases across the entire flight booking funnel—from flight search to booking creation and post-booking fulfillment. Impacting Global Reach: Building scalable services that integrate new airline partners and support our B2B distribution network, enabling Hopper’s growth worldwide. System Reliability: Contributing directly to the design and implementation of highly resilient, low-latency services that ensure a trustworthy and seamless experience for customers under high load. What You Will Lead and Build: You will be embedded within a cross-functional team, making substantial code contributions to a complex, high-throughput microservices environment. Key areas of contribution include: End-to-End Feature Development: Designing, implementing, and deploying high-quality code for new flight product features, taking them from concept to production. System Enhancement: Participating actively in discussions around system design, identifying opportunities to improve service scalability, performance, and monitoring (SLOs/SLAs). Integration Projects: Leading the technical implementation of new integrations with external airline and GDS partners, navigating complex communication protocols and data schemas. Code Quality and Mentorship: Upholding high standards for code quality through thorough code reviews, mentoring more junior engineers on best practices, and driving engineering excellence. What would your day-to-day look like: Implementation and Review: Writing clean, performant code, contributing significantly to the codebase, and performing code reviews to maintain quality and share knowledge. Technical Problem Solving: Collaborating with senior engineers to troubleshoot, debug, and resolve challenging production issues in a distributed system. Requirements Planning: Partnering with Product Managers and Product Operations to understand business requirements, decompose features into technical tasks, and estimate delivery timelines. System Exploration: Deeply exploring and improving the existing codebase and contributing to engineering improvements for the core flights product.
