Principal Site Reliability Engineer

Principal Site Reliability Engineer

As a Principal Site Reliability Engineer, you will play a strategic and technical leadership role in shaping the reliability, scalability, and velocity of our engineering platform. Your primary focus will be advancing our Kubernetes-based infrastructure and CI/CD systems to support high-scale, high-availability services. You will partner with engineering leaders across the organization to define and drive platform-wide initiatives that enable fast, safe, and repeatable deployments, and foster a culture of reliability and operational excellence.

Key Responsibilities

• Lead the design and evolution of Kubernetes-based infrastructure to support multi-tenant, high-scale applications with strong isolation, resilience, and security.
• Architect and optimize CI/CD pipelines to support fast and reliable build, test, and deploy cycles across a polyglot environment.
• Establish and evangelize best practices for GitOps, canary deployments, rollback strategies, and progressive delivery.
• Define and implement scalable Infrastructure as Code (IaC) patterns using tools such as Terraform, Helm, and Crossplane.
• Drive the adoption of automated testing throughout the delivery lifecycle—unit, integration, load, and chaos testing—to ensure high confidence in production changes.
• Guide teams in designing for observability, SLOs, and alerting, ensuring actionable signals and minimizing alert fatigue.
• Partner with security, compliance, and development teams to ensure infrastructure and delivery systems meet modern security and governance standards.
• Lead incident response retrospectives and foster a blameless culture of continuous improvement.
• Mentor and influence senior engineers across multiple teams, helping to up-level platform reliability capabilities organization-wide.

Qualifications

• 8+ years of experience in Site Reliability Engineering, DevOps, or Infrastructure roles, with 2+ years in a technical leadership or principal capacity.
• Deep expertise with Kubernetes internals (controllers, networking, autoscaling, operators, etc.) and production-grade clusters on cloud providers (EKS, GKE, or AKS).
• Proven experience designing and scaling CI/CD systems using tools such as GitHub Actions, Argo CD, Tekton, Spinnaker, or similar.
• Strong proficiency in Terraform and modern IaC practices.
• Advanced knowledge of automated testing strategies, including performance, load, and failure testing.
• Proficient in one or more programming/scripting languages (Python, Go, Bash, etc.).
• Deep experience with monitoring and observability stacks such as Prometheus, Grafana, OpenTelemetry, and Datadog.
• Strong communicator with the ability to align technical initiatives to business objectives and influence across engineering teams.

Nice-to-Have

• Experience implementing multi-cluster or multi-region Kubernetes strategies.
• Exposure to chaos engineering and building resilient distributed systems.
• Familiarity with compliance frameworks (SOC 2, HIPAA, etc.) as they relate to infrastructure and deployment.
• Contributions to open-source Kubernetes tooling or SRE frameworks.
• Familiarity with JVM- or Node-based application stacks.
