Introduction to the Team:
Our Technology Team partners with teams across Expedia Group 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.
As a Principal Engineer, you will be part of an agile development team with deep expertise in cloud, distributed systems, and observability. You will play a pivotal role in crafting the strategic technical goals for our group. The main effort will involve leading the architecture, design, and implementation of a centralized, scalable, and cost-effective observability platform used by all engineering teams across Expedia.

In this role, you will:
Architect and Build Core Telemetry Pipelines: Lead the design and implementation of highly scalable and resilient telemetry pipelines for logs, metrics, and traces. Evolve our platform to handle a 10x increase in data volume while maintaining performance and cost-effectiveness
Drive OpenTelemetry Adoption: Spearhead the strategy, rollout, and support for the OpenTelemetry collector across thousands of services. Develop best practices and automated configurations to ensure seamless and consistent data collection
Implement Platform Governance and Optimization: Design and build capabilities for data governance, cost allocation, and resource management within the observability platform. Define and implement SLOs for the platform itself and create tools to help teams manage their observability costs

Technical Leadership and Mentorship: Act as a force multiplier. Mentor senior engineers on the team, lead architecture review sessions, and author RFCs to build consensus on significant technical decisions. Your influence will extend beyond the team to application developers and SREs
Production Debugging: Serve as the final escalation point for complex, cross-cutting production incidents related to the observability platform, from telemetry agent bugs to data correlation failures in our distributed systems
Collaborate and Innovate: Explore and utilize a wide variety of technologies and tools, such as (but not limited to) Go, Java, Python, AWS, Kubernetes, OpenTelemetry, Prometheus, Grafana, Datadog, and Splunk, Clickhouse
Minimum Qualifications:
Bachelor’s or Master’s degree in Computer Science or a related technical field, or equivalent practical experience
10+ years of experience in software engineering, with a focus on building and operating large-scale distributed systems, infrastructure automation, or configuration management

Proficient in one or more of: Go, Java, Python
Solid understanding of cloud-native architectures (Kubernetes, Docker, microservices) and major cloud platforms (AWS preferred)
Preferred Qualifications:
Experience designing, building, and operating highly available, scalable, and resilient platforms
Excellent hands-on coder who understands and appreciates bigger-picture architectural and business concerns
