The Air Shopping Platform team at Expedia Group builds the platform capabilities that power every flight search in our shopping funnel. When a traveler searches for flights on Expedia, our systems work behind the scenes to surface the most relevant itineraries based on personalization, preferences, and real-time supply, enabling fast and confident decision-making. As customers move forward, we focus on providing price stability, frictionless bags and seat selection, and a seamless handoff into booking, minimizing surprises and maximizing trust. If you're excited about enriching the end-to-end flight shopping journey at scale, join us and help deliver delightful experiences for millions of travelers worldwide.
As a Senior Software Engineer on the Air Shopping Platform, you will own the experience immediately after a traveler selects a flight in search and lands on the flight details page. Your services will power the presentation of rich itinerary information — including layovers, duration, and price summaries — as well as bags, seats, and other ancillaries. This includes orchestrating calls to downstream connectivity partners (GDS, NDC, and other suppliers), reconciling updated itineraries and ancillary options across a stack of 15+ services, and ensuring customers can confidently proceed with minimal surprises. In this role, you will be expected to drive end-to-end delivery of key product and business initiatives, identifying experience gaps and leading the work to close them. You will deeply analyze and evolve the services in the stack, leading technical modernization, performance optimizations, and architectural improvements so that we operate at the level of the best platforms in the world. You will also be responsible for the resilience and observability of these high-scale services — designing robust failure handling, setting up effective alerting and monitoring, and proactively addressing reliability and latency issues to safeguard the customer journey.
In this role, you will:
- Design, build, and maintain complex, highly available services and applications, including robust system design (low-level design), API design, and data modeling across multiple domains.
- Lead end-to-end delivery of features and services, from technical design and implementation through deployment, monitoring, and ongoing optimization in production environments.
- Improve technical quality and operational excellence by driving code quality standards, reducing incidents, enhancing observability, and optimizing performance and reliability.
- Mentor and guide other engineers, sharing best practices in software engineering, testing, and architecture, and fostering a culture of continuous improvement and learning.
- Collaborate with product, design, data, and other engineering teams to translate business and customer problems into scalable technical solutions that can be reused across domains.
- Safely integrate and operate AI/ML‑enabled solutions that improve outcomes, including familiarity with AI-driven systems, tools, or workflows and applying 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.
- 8+ years of relevant professional experience.
- Proven experience owning end-to-end delivery for services or components, including design, implementation, testing, deployment, and support within a multi-service or domain environment.
- Strong proficiency in at least one modern programming language and core software engineering practices, including object-oriented design, data structures, algorithms, testing, and version control.
- Hands-on experience designing and consuming APIs, working with data models and storage systems, and applying system design principles to build reliable and maintainable systems.
Preferred Qualifications:
- Experience designing and evolving service and application architectures for high-traffic, distributed systems, including clear API contracts, data models, and low-level designs.
- Demonstrated track record driving technical direction for services or domains, making data-informed tradeoffs on scalability, reliability, performance, and cost.
- Strong focus on operational excellence, including monitoring, alerting, incident response, and continuous improvement of production systems and developer workflows.
- Familiarity with AI-driven systems, tools, or workflows and applying AI/ML concepts to real world products, including safely integrating AI/ML‑enabled features into existing services.
- Experience leading cross-team technical initiatives or migrations, influencing engineering best practices across a domain, and mentoring others to grow their technical depth and delivery capability, including guiding teams on effective and responsible use of AI-assisted development and testing tools.
