Hundreds of models across Expedia, Vrbo and Hotels.com run on what we help build, so the code you ship is felt quickly and good engineering habits (tests, observability, clear PRs) are valued as much as raw output. We lean heavily on coding agents (Cursor, Claude Code and friends) to accelerate the delivery cycle: scaffolding services, drafting tests, reviewing PRs and keeping documentation in step with the code. You'll have space to learn how to get the best out of them and we'll look to you to apply good judgement on what lands in main. In this role, you will: Design, build, test, and maintain reliable software components that deliver high-quality customer and business outcomes. Translate product and technical requirements into maintainable solutions, applying sound engineering practices across the software development lifecycle. Develop clear low-level designs, APIs, data models, and integrations that support scalable, secure, and dependable services. Investigate and resolve complex technical issues, improve system performance and reliability, and contribute to operational excellence. Collaborate effectively across engineering, product, and technical domains while applying transferable skills to multiple problem spaces. Safely integrate and operate AI/ML-enabled solutions that improve outcomes, while building familiarity with AI-driven systems, tools, workflows, and the application of AI/ML concepts to real-world products. Minimum Qualifications: Bachelor’s degree in computer science, engineering, or a related technical field, or equivalent practical experience. Demonstrated professional software engineering experience appropriate to an SDE II role. Experience owning and delivering features or components within a service or defined technical area. Proficiency in software development fundamentals, including coding, testing, debugging, version control, API design, data modeling, and low-level system design. Experience working with cross-functional partners to deliver, operate, and improve production software. Preferred Qualifications: Experience designing and operating reliable services at scale, with a focus on performance, availability, security, and maintainability. Demonstrated ability to contribute to architectural decisions, simplify complex technical problems, and improve engineering practices within a defined service or domain. Experience using monitoring, logging, metrics, and data-driven analysis to diagnose issues and guide technical improvements. Practical exposure to AI/ML-enabled products, developer tools, or workflows, including the ability to evaluate and safely apply these solutions in production-oriented software engineering. Experience delivering technical solutions across multiple domains or technology areas, with the adaptability to apply sound engineering judgment in unfamiliar problem spaces.

Introduction to team: the engineering organization responsible for Reservations across two of Expedia Group's largest lines of business: Conventional Lodging (hotels) and Vacation Rentals (Vrbo). This platform ensures that the booking is completed across all systems starting from the moment a traveller clicks "book" till the moment a supplier, a hotel property or a vacation rental host, actually confirms that room or home. It is the system of record and execution for every reservation created, retrieved, changed, cancelled, and reconciled across every EG brand and every point of sale, globally. The scale of these platforms is substantially high since Conventional Lodging alone represents a large majority of Expedia's transaction volume, processing bookings across local inventory, third-party inventory, and GDS supply. Vacation Rentals adds a second, structurally distinct booking model, whole-property rentals with owner/property-manager supply, dynamic quote-and-hold flows, and its own settlement and payout mechanics. Across both businesses, this organization owns dozens of production services spanning booking orchestration, price/availability validation, fulfilment, cancellation, change management, settlement, and event publishing to finance and analytics. Typical technologies include Java/Kotlin, Spring, REST/gRPC, AWS, Datadog and Splunk. Platform capabilities you will own and continue to raise the bar on: Scalability — supporting booking, retrieve, and post-booking traffic that scales across markets, brands, and business models without re-architecting for every new use case. High-performance — the team is actively driving end-to-end booking latency down, because every additional second at checkout measurably costs conversion and revenue. High throughput — the platform must absorb booking, price-check, and inventory-adjustment traffic at production scale continuously, including peak demand events, without degrading the traveller experience. Resiliency — this is a highly compliant and audited revenue-critical system, designed with redundancy, safe rollout mechanisms, and recovery paths, because a failed booking is a failed sale. In this role, you will: Define and evolve technical direction for complex products, services, and domains, delivering scalable solutions that support business and customer outcomes Lead architecture and system design, including low-level design, API design, data modelling, and evaluation of technical trade-offs across interconnected systems Drive engineering execution across multiple services or a broad technical domain, aligning teams on priorities, delivery approaches, and sustainable technical practices Apply deep technical expertise to solve ambiguous, high-impact problems while remaining effective across multiple engineering domains and technology stacks Establish operationally excellent solutions through practices that strengthen reliability, observability, performance, security, maintainability, and continuous improvement Safely integrate and operate AI/ML-enabled solutions that improve outcomes, applying familiarity with AI-driven systems, tools, workflows, and AI/ML concepts to real-world products Minimum Qualifications: Bachelor’s degree in Computer Science or a related technical field; or Equivalent related professional experience 12+ years of relevant professional experience Demonstrated ownership of complex systems and broad technical domains, with experience leading technical direction and architecture across multiple services, teams, or a significant engineering domain Strong expertise in system design, including low-level design, API design, data modelling, software development, and evaluation of scalable technical solutions Demonstrated ability to deliver reliable, maintainable, and secure systems while influencing engineering decisions across organizational boundaries Preferred Qualifications: Proven experience designing and operating high-scale, distributed, or business-critical systems with strong reliability and performance requirements Demonstrated architecture leadership across complex, multi-service environments, including successful resolution of cross-team technical dependencies and trade-offs Experience using data and operational insights to guide engineering strategy, improve system outcomes, and prioritize technical investments Advanced familiarity with AI/ML-enabled products or engineering workflows, including evaluating, integrating, and operating AI-driven solutions responsibly in production A record of advancing engineering excellence through technical mentoring, reusable patterns, automation, and continuous improvement across a broad engineering organization Accommodation requests Expedia Group is committed to providing an inclusive and accessible recruiting experience.
