Site Reliability Engineer (EMEA Hours)

About the role

Expedia Group is building a new AI Ops Engineering team focused on reliability, incident response and operational excellence for its travel platforms (Expedia, Hotels.com, Vrbo and the B2B business). The role covers EMEA hours in a follow-the-sun team, handing over to the next region at the end of the shift, in a cloud-first AWS environment. It is about operational ownership, not building models.

Key responsibilities

• Own production health during EMEA hours and hand over cleanly to the next region.
• Act as first-line responder for production incidents: triage, troubleshoot, escalate and resolve within SLAs.
• Contribute across the full incident lifecycle, detection to follow-up, and take part in blameless post-incident reviews (RCA, 5 Whys).
• Build, tune and maintain alerts, dashboards and monitors, and reduce alert fatigue.
• Investigate issues across distributed systems on AWS using logs, metrics and traces (Splunk, Datadog or similar).
• Write runbooks, handover notes and operational documentation.
• Automate repetitive work with scripting and, where useful, infrastructure as code.
• Work with software engineers, platform teams and data/ML partners to improve operability of production services, including AI workloads.
• Take part in shift rotations including weekends, and communicate with technical and non-technical stakeholders during incidents.

Required profile

• Relevant technical degree or equivalent practical experience.
• Hands-on experience handling production incidents, including on-call or shift work under pressure.
• Working knowledge of the incident lifecycle and root cause analysis techniques such as 5 Whys.
• Clear written English, including structured shift handovers and incident updates.
• Willingness to work EMEA shifts, including weekends on a rotating basis.

Required skills

• Monitoring, logging and observability tools (Splunk, Datadog, Grafana, Prometheus, ELK, New Relic, CloudWatch)
• Creating, configuring and tuning alerts and monitors
• Solid troubleshooting across applications, networks and cloud infrastructure
• Working experience with AWS as a primary cloud platform
• Scripting (Python, Bash or similar) to automate operational tasks
• Preferred: Splunk/Datadog, Terraform or CloudFormation, PagerDuty/Opsgenie/ServiceNow, SLI/SLO definition, multi-region operations experience, AI/ML production support, and a track record of reducing incident volume or MTTR

What we offer

• Cash range in Prague of CZK 1,077,000 to CZK 1,507,500, with potential to reach CZK 1,723,000 on sustained performance.
