Senior Site Reliability Engineer (Arlington, VA)

What You'll Do

• Implementing a World-Class Observability Platform: Design, implement, and manage our monitoring, logging, and alerting stack (e.g., Prometheus, Loki, Alloy, and Grafana). Create actionable insights and automated alerting 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).
• Leading Incident Response: Act as the incident responder and potentially incident commander during critical incidents. Lead blameless post-mortems / After Action Reviews (AARs) that identify root causes and drive automated, long-term solutions.
• 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). Embed security and compliance controls (RMF, STIGs) into automation.
• Eliminating Toil and Scaling the Team: Proactively identify and eliminate operational toil by building automation. Partner with other teams to share best practices for air-gapped environments.
