This includes compensating for downstream services that are not in Expedia's control. We are also looking to use cloud computing (AWS) to further solidify our infrastructure. This opportunity presents you with great technical challenges and the ability to have a tremendous business impact. We do this accurately and at scale, processing over $100 billion payments in 60+ currencies in over 155 countries every year across diverse payment options.

What you'll do:

• Design and build end-to-end backend solutions for Payments, that are scalable, resilient, and performant. *
• Own and evolve core payment services and workflows, including payment session lifecycle, payment-method orchestration, and downstream service integrations. *
• Build and enhance backend APIs and service interfaces using Kotlin/Java and modern service frameworks, with strong emphasis on clean contracts, backward compatibility, and operational reliability. *
• Develop and support GraphQL, gRPC, and REST-based integrations that power payment experiences across multiple Expedia Group brands and checkout surfaces. *
• Contribute to distributed system design for high-volume, multi-tenant, 24x7 payment flows, balancing latency, availability, security, and maintainability. *
• Build robust integrations with payment providers, internal platforms, and shared infrastructure while ensuring fault tolerance and graceful degradation. *
• Take strong ownership of production systems, including monitoring, alerting, on-call participation, incident response, and root cause resolution. *
• Build and enhance observability through logs, metrics, traces, dashboards, and operational playbooks to proactively detect and prevent issues. *
• Troubleshoot and resolve production issues with urgency, minimizing customer, partner, and business impact in high-transaction environments. *
• Continuously improve system reliability, deployment safety, and engineering effectiveness through CI/CD, rollback strategies, feature flags, test automation, and performance tuning. *
• Collaborate closely with product managers, designers, frontend engineers, partner teams, and platform teams to deliver reliable, intuitive, and scalable payment capabilities. *
• Mentor junior engineers and drive engineering best practices across backend design, coding standards, testing, operational excellence, and incident management. *
• Lead technical discussions, code reviews, architecture reviews, and design decisions across the team and broader payments ecosystem. *
• Influence cross-functional delivery and act as a subject matter expert for backend payment architecture, scalability, and service reliability.

Who you are:

• 5+ years of experience in software development with strong backend engineering expertise. *
• Deep hands-on experience in Java and/or Kotlin, with strong object-oriented design and distributed systems fundamentals. *
• Strong experience building and supporting web services and APIs in high-transaction, highly available production environments. *
• Experience designing and maintaining scalable backend architectures for customer-facing, business-critical systems. *
• Strong understanding of data structures, algorithms, concurrency, multithreaded programming, and system-level design. *
• Experience with service-oriented and distributed architectures, including service versioning, backward compatibility, and dependency management. *
• Strong experience with API design and integration patterns across REST, GraphQL, and/or gRPC. *
• Familiarity with payment flows, session-driven architectures, provider integrations, and high-scale transactional systems; payments domain experience is a strong plus. *
• Strong understanding of reliability engineering, including monitoring, alerting, incident management, root cause analysis, and operational readiness. *
• Experience building automation, developer tooling, dashboards, or reporting capabilities to improve service visibility and team productivity. *
• Experience with cloud platforms and modern deployment practices; AWS experience preferred. *
• Knowledge of performance engineering, application tuning, load testing, and scalability optimization. *
• Strong understanding of Software Development Lifecycle practices, testing strategies, and agile engineering processes. *
• Proven ability to lead code reviews, design reviews, and technical decision-making across teams. *
• Proven track record of mentoring engineers, raising the quality bar, and influencing engineering excellence beyond immediate project scope. *
• Strong written and verbal communication skills, with the ability to articulate architecture and implementation tradeoffs in technical forums. *
