You’ll work on mission-critical systems operating at massive scale, solving complex distributed systems problems while helping shape the future of travel technology.

In this role, you will:

• Design, build, and own high-quality, scalable, and resilient software services and components, including system design (low-level design), API design, and data modeling aligned to Expedia Group engineering standards.

• Lead end-to-end implementation of complex features and services across the full software development lifecycle, from technical design and coding through testing, deployment, and ongoing operational support.

• Drive technical direction within your team by evaluating trade-offs, making data-informed decisions, and setting engineering best practices for code quality, observability, testing, and performance.

• Collaborate closely with product, design, and partner engineering teams across multiple domains to deliver integrated solutions that meet functional, reliability, and scalability requirements.

• 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.

• Proactively identify, debug, and resolve production issues, improve system reliability, and reduce operational toil through automation, monitoring, and continuous improvement initiatives.

Minimum Qualifications:

• Bachelor’s degree in Computer Science or a related technical field; or Equivalent related professional experience.

• 8+ years of relevant professional experience.

• Demonstrated ownership of one or more services or components, including responsibility for technical design, implementation, quality, and operational health.

• Proficiency in system design (LLD), API design, and data modeling, with the ability to design for scalability, reliability, and maintainability.

• Experience with service-oriented or microservices architectures, including automated testing, continuous integration/continuous delivery (CI/CD), and production monitoring practices.

Preferred Qualifications:

• Experience designing and evolving large-scale, distributed systems or high-traffic services, including performance tuning, capacity planning, and resilience engineering.

• Track record of providing technical leadership within a team, including reviewing designs and code, mentoring other engineers, and influencing engineering best practices across services or domains.

• Deep experience with observability and operational excellence, including metrics, logging, alerting, incident response, and post-incident analysis to drive long-term improvements.

• Hands-on experience integrating AI/ML‑enabled features or services safely into production systems, including working with AI/ML platforms, SDKs, or APIs and managing associated risks such as quality, security, and misuse.

• Familiarity with AI-driven systems, tools, or workflows for accelerating development (such as code generation, intelligent testing, or operational insights), and applying these responsibly to improve engineering productivity and product outcomes.
