Site Reliability Engineer

At Expedia Group, we help travelers explore the world, one journey at a time. As a global travel company powered by passionate people, trusted partnerships, and leading technology, we connect travelers, partners, and advertisers through our consumer brands, B2B network, and travel advertising business.

Here, you'll do meaningful work that helps millions of people discover, book, and experience travel with more ease, confidence, and joy. Our five Behaviors-Traveler First, Think Big, Operate with Excellence, Ownership Mindset, and Succeed Together-help foster a supportive environment where people can grow their careers and have the flexibility, benefits, and support to do their best work. Join us and build for travelers everywhere.

We are building a new AI Ops Engineering team at Expedia Group focused on reliability, incident response, and operational excellence for one of the world's largest e-commerce and online travel platforms, which powers Expedia, Hotels.com, Vrbo, and our B2B travel business. The team operates in a follow-the-sun model with colleagues across regions. This role covers EMEA hours, handing over to the next region at the end of the shift. We keep production services, including AI-enabled ones, healthy, observable, and recoverable in a cloud-first AWS environment, so travelers can search and book without disruption. We apply SRE and DevOps principles to detect problems early, respond fast under pressure, hand over cleanly, and learn from every incident so it doesn't happen twice. This role is about operational ownership, not building models.

In this role, you will

• Own production health during EMEA hours as part of a follow-the-sun team, and hand over cleanly to the next region.
• Act as a first-line responder for production incidents affecting Expedia Group's travel platforms: triage, troubleshoot, escalate, and drive issues to resolution within defined SLAs.
• Contribute across the full incident lifecycle: detection, response, communication, mitigation, recovery, and follow-up.
• Take part in blameless post-incident reviews using structured methods such as RCA and 5 Whys, and track corrective actions through to completion.
• Build, tune, and maintain actionable, low-noise alerts, dashboards, and monitors, and reduce alert fatigue.
• Use logs, metrics, and traces (Splunk, Datadog, or similar) to investigate issues across distributed systems on AWS.
• Write and maintain runbooks, handover notes, and operational documentation so knowledge is shared across regions.
• Automate repetitive operational work using scripting and, where useful, infrastructure as code.
• Work with software engineers, platform teams, and data/ML partners across Expedia Group to improve the operability of production services, including AI-powered workloads.
• Participate in shift rotations, including weekends, and communicate clearly with technical and non-technical stakeholders during incidents.

Minimum Qualifications

• Relevant technical degree or equivalent practical experience.
• Hands-on experience handling production incidents, including on-call or shift-based work and operating under pressure to restore service.
• Working knowledge of the incident lifecycle (severity classification, escalation, communication, post-incident review).
• Experience with root cause analysis techniques such as 5 Whys and writing clear post-incident reports.
• Practical experience with monitoring, logging, and observability tools (Splunk, Datadog, or equivalents such as Grafana, Prometheus, ELK, New Relic, CloudWatch).
• Experience creating, configuring, and tuning alerts and monitors.
• Solid troubleshooting skills across applications, networks, and cloud infrastructure.
• Working experience with AWS as a primary cloud platform.
• Scripting ability (Python, Bash, or similar) to automate operational tasks.
• Clear written English, including structured shift handovers and incident updates.
• Willingness to work shifts covering EMEA hours, including weekends on a rotating basis.

Preferred Qualifications

• Direct experience with Splunk and/or Datadog (queries, dashboards, monitors, SLOs).
• Experience with infrastructure as code (Terraform, CloudFormation).
• Experience with incident tooling such as PagerDuty, Opsgenie, or ServiceNow.
• Experience defining SLIs/SLOs and driving reliability improvements from incident trends.
• Experience working in a distributed, multi-region operations team, handing over between time zones.
• Exposure to supporting AI/ML-enabled services in production.
• Track record of reducing incident volume, MTTR, or alert noise through automation and process improvement.
