As a technical leader and contributor on the Flights team, you will partner closely with other engineers to drive change and improve systems and developer experience. Although you will be at one of our highest levels of seniority, all individual contributors are expected to be hands-on and contribute code.

Collaborate closely with product managers and designers, ship high-impact features, monitor their operational health, and ensure key technical decisions directly drive exceptional quality, user value, and positive business outcomes. • Collaborate Across Teams: Work effectively as part of a global, cross-functional team, partnering with fellow engineers, product managers, designers, and business leaders to deliver impactful solutions and elevate team performance. • Elevate Engineering Culture: Champion engineering excellence, setting the standard for code quality, scalability, documentation, and testing. Mentor team members to foster continuous growth and technical mastery.   What We're Looking For: • 10+ years of experience building and scaling complex systems in fast-paced, high-growth, or large-scale environments. • A strong product mindset with genuine empathy for the user and a relentless drive to deliver an exceptional customer experience. • A proven track record as a hands-on coder who balances high-volume, high-quality code output with technical leadership. • In-depth experience with Java, Spring Boot, and AWS (or other cloud provider), including a deep understanding of JVM performance, optimization, and cloud architecture. • Strong expertise in distributed systems, microservices, and API design. • Ownership mentality with a record of delivering production-quality, maintainable code, and supporting features post-release through monitoring and troubleshooting. • Demonstrated ability to operate comfortably in highly ambiguous environments, thinking creatively to develop and implement solutions. • Collaborative team player able to work effectively with global, cross-functional partners. • Commitment to engineering excellence across the software development lifecycle. • Problem-solving mindset with a passion for tackling technically demanding and customer-impacting challenges. • Domain knowledge in the travel industry (flights, bookings, or inventory management) is a strong plus. • Bachelor’s or Master’s degree in Computer Science, Engineering, or related field, or equivalent hands-on experience.
