• Experience analyzing web performance using metrics and tools such as Core Web Vitals, LCP, TTFB, Real User Monitoring, Lighthouse, or comparable observability tools.
• Proven ability to investigate and resolve complex issues in live production environments using a structured, evidence-based troubleshooting process.
• Experience owning a customer launch, technical implementation, or migration end-to-end, including pre-launch validation, go/no-go decisions, and post-launch monitoring.
• Ability to communicate technical risks, limitations, delays, and difficult findings clearly to both technical and non-technical customers.
• Comfort making and explaining rough technical estimates related to traffic, latency, capacity, percentages, and performance impact.
• Advanced English communication skills.
• Availability for at least four hours of daily overlap with US Eastern business hours.
