Senior Site Reliability Engineer

Responsibilities

• Build and operate the delivery platform.
• Work across AWS, EKS, ArgoCD, Helm, GitHub Actions, Azure DevOps, Terraform, and Python.
• Fix the problems you own. Find root cause across the AWS and Kubernetes stack, fix it, and harden it so it stays fixed.
• Respond to incidents. Help stabilize during outages, drive root-cause analysis, and ship corrective actions for your systems.
• Standardize how we build and ship. Define reproducible container builds and GitOps paths on ArgoCD and Helm that replace manual deployment.
• Help consolidate the CI estate. Standardize pipelines across GitHub Actions and Azure DevOps for your services — remove brittle steps and silent failures and improve visibility.
• Support platform adoption. Build golden-path templates and tooling and help teams move services onto the platform.
• Use progressive delivery. Canary and blue green deploys (Argo Rollouts) and automated rollback for the services you operate.
• Build observability in. Wire golden-signal metrics, logs, and traces (Prometheus/Mimir, Loki, Tempo, OpenTelemetry) into your services, surfaced in Grafana with SLOs for your domain.
• Operate production systems. Troubleshoot failed to deploy, respond to alerts, and improve behavior from real incidents.
• Help meet SLOs and carry on call. Track reliability metrics for the services you operate and share the rotation.
• Built across environments. Design dev, test, and prod for safe promotion, recovery from failed deployments, and zero-downtime upgrades.
• Help set the standard. Build reference implementations for build, deploy, GitOps, promotion gates, and observability.
• Uphold compliance with the pipeline. Support deployment traceability, approval trails, and segregation of duties for PCI DSS, SOC 2, SOX, and GLBA.
• Cut toil and cost. Automate repetitive ops work and help tune EKS compute, CI runners, and observability cardinality.
• Unblock across teams. Get hands-on with Cloud, Security, Application Engineering, Data, and Product to keep delivery moving.
• Kill knowledge silos. Write docs, runbooks, and incident learnings, so engineers operate independently.

Qualifications

• Kubernetes, ArgoCD, Helm, Terraform, Python.
• Deep hands-on production experience.
• Hands-on AWS.
• Operate and debug EKS, ECS, EC2, ECR, IAM/IRSA, VPC networking, ALB/NLB, CloudWatch, Secrets Manager, and KMS.
• Github Actions and/or Azure DevOps.
• Build and operate CI/CD at scale.
• Grafana and the observability stack. Hands-on with Grafana dashboards and alerting, and the metrics, logs, and traces stack (Prometheus/Mimir, Loki, Tempo, OpenTelemetry).
• Strong scripting. Python and Bash, with the ability to grow into systems-level coding.
• Production troubleshooting. Comfortable getting into a system under load, finding root cause, and fixing it.
• Production ownership. Uptime and reliability accountability.
• Incident response. You respond and help drive postmortems that yield real improvements.
• Standards contribution. You contribute to engineering standards and best practices.
• Compliance awareness. Experience in regulated or high-rigor environments or implementing audit and access controls in pipelines.
• Mentorship. Through code review, examples, and pairing.
