Senior Site Reliability Engineer

Responsibilities

• Reliability Engineering & Operations - Own and improve service reliability through SLO/SLI definition, error budgets, and operational best practices.
• Design, implement, and maintain observability (monitoring, logging, tracing, alerting) to reduce MTTR and improve proactive detection.
• Lead incident response practices including on-call improvements, runbooks, post-incident reviews (RCA), and preventative actions.
• Partner with application teams to improve performance, capacity planning, and resiliency under failure scenarios.
• Infrastructure & Cloud Architecture - Design and operate highly available, fault-tolerant Cloud architectures (multi-AZ and, where required, multi-region); implement resilient patterns across compute, storage, networking, and managed services (autoscaling, load balancing, backups, replication).
• Drive cloud governance best practices (tagging, account/landing zone patterns, least privilege, guardrails) in partnership with security and platform teams.
• Infrastructure as Code (IaC) & Dev Ops Enablement - Build and maintain IaC modules and standards (Terraform, Cloud Formation, CDK); develop, standardize, and optimize CI/CD pipelines to enable safe, automated deployments (Git Hub Actions, Git Lab CI, Jenkins, AWS Code Pipeline); promote Dev Ops practices: version-controlled infrastructure, automated testing, immutable deployments, progressive delivery patterns; establish environment consistency across dev/test/stage/prod and ensure infrastructure drift detection and remediation.
• BCP/DR, RTO/RPO Definition & Testing - Collaborate with stakeholders to evaluate and define service-level RTO and RPO targets; design and implement BCP/DR architectures and procedures; coordinate structured DR tests (tabletop, simulation, partial failover, full failover) and document outcomes; maintain DR runbooks, dependency maps, and recovery checklists; produce metrics and reporting on DR readiness, test results, and continuous improvement actions.
• Ability to work effectively in a fast-paced, dynamic and high-intensity environment, with timely responsiveness and the ability to work beyond normal business hours when required.

• 7+ years of experience in SRE, Dev Ops, Platform Engineering, or Systems Engineering roles supporting production environments.
• Strong proficiency with observability platforms (Datadog, Prometheus/Grafana, ELK/Open Search, Nagios, Nimsoft, etc).
• Strong hands‑on AWS experience building and operating production systems.
• Proven expertise with Infrastructure as Code (Terraform and/or Cloud Formation/CDK).
• Strong CI/CD and automation background (pipeline design, deployment strategies, testing automation).
• Experience defining and validating RTO/RPO, and implementing BCP/DR plans with structured testing.
• Experience with Kubernetes and auto-scaling container platforms (EKS, ECS, or Kubernetes on-prem).
• Strong Linux fundamentals, networking concepts (DNS, TCP/IP, load balancing), and troubleshooting skills.
• Proficiency in at least one scripting/programming language (Python, Go, Bash, or similar).
• Ability to write clear operational documentation, runbooks, and post-incident reports.

• Familiarity with Azure and/or Oracle Cloud (OCI).
• Familiarity with Service Mesh, API Gateways, and distributed tracing tooling.
• Familiarity with Open Telemetry, client instrumentations and collector configurations.
• Security and compliance familiarity in cloud environments (IAM design, secrets management, audit logging).
• Experience implementing progressive delivery (blue/green, canary), feature flags, and automated rollback.
• Relevant certifications (AWS Solutions Architect/Dev Ops Engineer, Kubernetes CKA/CKAD).
• Experience with ArgoCD & Karpenter.

• Competitive comprehensive medical, dental, retirement and life insurance benefits.
• Employee assistance & wellness programs.
• Parental and family leave policies.
• CCI Community volunteering program - 2 days annually to volunteer at selected charities.
