Qualifications

• 6+ years in SRE, platform reliability or observability engineering, with strong hands-on AWS experience.

• Tracing: Set up end-to-end tracing across agent steps, model calls, tool calls and multi-agent handoffs so issues can be traced to their source.
• SLOs and Alerting: Define SLOs for latency, availability and error rates, and build alerting that is useful and not noisy.
