• Extend our observability stack (Prometheus, Honeycomb, OpenTelemetry) and guide teams as they scale workloads across our HashiCorp Nomad service fabric.
• Design and run tabletop exercises and fault-injection testing to stress-test the platform against real-world failure and volatility scenarios.
• Mentor engineers across teams to build a culture of site reliability champions so the practice outlives any one person.

• Production-quality coding experience in Ruby and/or Java, plus Python for automation.
• A track record embedding SRE practices within engineering teams, including SLOs, error budgets, and burn-rate alerting.

• Strong Linux internals and networking fundamentals, including TCP/IP, UDP/multicast, packet capture, and flow analysis.
