Participate in on‑call support and technical escalations. Lead customer‑impacting incident response and coordinate vendor escalations through resolution. Troubleshoot content publishing failures, cache invalidation issues, content‑source outages, and website availability problems. Maintain incident documentation, operational runbooks, and troubleshooting procedures.



Change and Release Reliability

Manage Git‑based production deployments and release processes for website and Edge configurations. Implement CI/CD controls, including branch protection, automated checks, code linting, performance testing, and secret scanning. Validate rollback procedures, including code reverts, content republishing, and cache purging. Improve the reliability and automation of frequent content publishing workflows. Coordinate release planning, deployment schedules, and release documentation. Minimize production risks through repeatable, controlled, and well‑tested deployment practices.

Maintain recovery documentation and ensure operational procedures are tested and current. Reliability and Web Performance Engineering

Define and monitor Service Level Objectives (SLOs) for website availability and performance. Monitor Core Web Vitals and investigate performance degradation.



Implement observability using Real User Monitoring (RUM), CDN access logs, external synthetic monitoring, and centralized logging. Analyze the performance impact of third‑party scripts, tags, and external integrations. Establish performance budgets and investigate performance regressions. Monitor CDN data transfer and egress, asset storage, media delivery, and platform costs. Prepare reliability, availability, and performance reports to identify improvement opportunities. Documentation and Continuous Improvement

Maintain operational runbooks, incident response procedures, support documentation, and escalation paths. Improve monitoring, alerting, incident response, and operational workflows. Maintain platform configuration records and clearly document support ownership. Collaborate with engineering and vendor teams to identify recurring issues and reduce incident frequency. Automate repetitive operational tasks and troubleshooting activities. Drive continuous improvements in platform reliability, production support, and release processes. WHAT YOU WILL BUILD AND IMPROVE
