Responsibilities
Implementing a World-Class Observability Platform: Design, implement, and manage our monitoring, logging, and alerting stack (e.g., Prometheus, Loki, Alloy, and Grafana). You won't just track metrics; you'll create the actionable insights and automated alerting that allow teams to identify and resolve issues before they impact users
Defining and Upholding Reliability: Define, measure, and own alerting that feeds into our Service Level Indicators (SLIs) and Service Level Objectives (SLOs), increasing trust internally and externally. You will be the organization's expert on what it means for our systems to be reliable and how to measure it
Leading Incident Response: Act as the incident responder and potentially incident commander during critical incidents who will lead blameless post-mortems / After Action Reviews (AARs) that identify true root causes and drive automated, long-term solutions to prevent recurrence
Automating for Scale and Security: Partner with platform engineers to design, build, and manage secure, resilient Kubernetes clusters and cloud/on-prem environments using Infrastructure-as-Code (Terraform, Ansible). You will embed security and compliance controls (RMF, STIGs) directly into this automation
Eliminating Toil and Scaling the Team: Proactively identify and eliminate operational toil by building automation. You will partner with other teams to share best practices for air-gapped environments and support their readiness for production
