Site Reliability Engineer

Responsibilities

• Own the observability platform end-to-end—Prometheus, Grafana, distributed tracing (Open Telemetry)—and establish SLO/SLI frameworks and track SLAs across all systems and applications.
• Lead major incident response as an incident commander; drive root‑cause analysis and systemic remediation programs.
• Lead the evolution of CWAN's cloud infrastructure on AWS, establishing scalability, resilience, and security standards across all services.
• Serve as the primary owner of the Kubernetes (EKS) platform: design cluster topology, multi‑tenancy models, autoscaling strategies, and upgrade lifecycle.
• Define and enforce the organization's Infrastructure‑as‑Code standards using Terraform and Ansible; drive adoption of GitOps workflows.
• Build and maintain CI/CD and automated deployment pipelines for all services and applications across environments.
• Evaluate and introduce emerging technologies (eBPF, WASM, service meshes) to improve platform capabilities.
• Partner with engineering leadership to embed reliability requirements into the SDLC; champion chaos engineering and resilience testing programs.
• Mentor and grow mid‑level and junior SREs across global teams through code reviews, pairing, and structured knowledge sharing.
• Drive capacity planning, cost optimization, and FinOps practices across the AWS environment.
• Contribute to the engineering roadmap and help define the long‑term reliability strategy for the CWAN platform.

Qualifications (Required)

• 7+ years of experience in Site Reliability Engineering, Platform Engineering, or related roles.
• Proven track record leading major incident response and driving post‑incident systemic improvements.
• Strong experience building and operating observability stacks at scale.
• Hands‑on experience with monitoring, logging, and tracing tools such as Grafana, Prometheus, Mimir, OpenSearch, Dynatrace/Datadog, Victoria Metrics, etc.
• Demonstrated ability to mentor engineers and influence technical direction across time zones.
• Deep expertise with Kubernetes in large‑scale, multi‑cluster production environments.
• Advanced proficiency with AWS (EKS, RDS/Aurora, ElastiCache, Direct Connect, IAM/SCP, Cost Explorer).
• Expert‑level Infrastructure‑as‑Code skills with Terraform (modules, remote state, Atlantis or similar).
• Hands‑on experience with CI/CD platforms: Jenkins, GitHub Actions, and GitLab CI.
• Experience with GitOps workflows (ArgoCD, Rancher).
• Proficiency in at least one general‑purpose programming language (Python, Go, Java) for building tooling and automation.
• Experience with security best practices in cloud environments (IAM least privilege, secrets management, etc.).

Preferred Qualifications

• Experience in financial services, FinTech, or other mission‑critical, regulated environments.
• Hands‑on experience with service mesh (Istio) and eBPF‑based observability tools.
• Prior staff or principal engineer experience with cross‑team technical influence in a global organization.
• AWS and Kubernetes certifications at the Professional level.
• Experience with multi‑region active‑active architectures and global load balancing.
