Introduction to Team

Expedia Technology teams partner with our Product teams to create innovative products, services, and tools to deliver high‑quality experiences for travelers, partners, and our employees. A singular technology platform powered by data and machine learning provides secure, differentiated, and personalized experiences that drive loyalty and traveler satisfaction.

We are hiring a hands‑on Principal Software Development Engineer to lead the design, implementation and operational excellence of our cloud infrastructure and platform capabilities. This role emphasizes platform engineering : designing and delivering a scalable, reliable, secure, observable, and cost‑efficient runtime platform (Kubernetes, containers, CI / CD, IaC, cloud services) used by multiple product teams. You will both set strategy and be embedded in the code and infrastructure to execute the roadmap end‑to‑end.

You will shape the foundational platform that powers customer‑facing services across brands, increasing developer velocity, reducing operational risk, and optimizing cloud spend. This role is ideal for a leader who can design complex systems, implement solutions in production, and lead broad cross‑team adoption.

What you will do

• Define the technical strategy, roadmap and standards for cloud infrastructure and platform capabilities (container runtime, orchestration, networking, CI / CD, observability, security, IaC)
• Lead migration and platform adoption efforts (containerization, Kubernetes / EKS, runtime platform) and drive roadmap execution end‑to‑end
• Be an active code and IaC contributor (Terraform / CloudFormation / Helm, platform services, automation) and perform design / code reviews
• Design scalable, resilient, and secure infrastructure patterns for microservices, data stores, caching, and messaging
• Build and improve CI / CD pipelines, release automation, testing strategies, and safe deployment practices
• Drive SRE and observability practices : define SLIs / SLOs, monitoring, tracing, alerting, runbooks, incident response, and post‑mortems
• Lead capacity planning, performance tuning, and traffic engineering for high‑scale workloads
• Own and evangelize AWS cost optimization practices (rightsizing, reserved / spot strategies, architecture changes, cost monitoring and show back)
• Define and enforce platform standards, security controls, environment tagging, and operational excellence practices across teams
• Mentor and grow senior and mid‑level engineers; identify high‑potential talent and raise engineering standards
• Collaborate closely with product, security, platform, and operations stakeholders to align technical solutions with business goals and compliance requirements
