Principal DevOps Engineer

About The Role As Principal DevOps Engineer, you are the architect of our engineering velocity. You won't simply manage servers — you will design the foundation on which our entire product ecosystem runs. Your mission is to build a Golden Path for developers: a seamless, automated, high-performance platform that turns complex infrastructure into a self-service utility. You will lead how we ship software, how we scale our global Kubernetes footprint, and how we maintain a world-class security and cost posture — against a weekly release cadence. Key Responsibilities – Platform orchestration. Architect and operate production-grade Kubernetes clusters with Terraform and Terragrunt, owning the full lifecycle of our compute environments. – Release strategy. Design and implement advanced deployment patterns — Blue/Green, Canary, feature flags — to deliver zero-downtime releases across a microservices architecture. – Infrastructure as Code. Standardize our multi-cloud and hybrid infrastructure. If it isn't in code, it doesn't exist — our IaC must be modular, tested, and scalable. – CI/CD leadership. Optimize GitHub Actions and GitLab CI pipelines to cut build times and tighten feedback loops, and own the code-governance strategy across branch protection and automated compliance. – Performance & observability. Partner with Performance Engineering to embed automated benchmarking into the pipeline and build comprehensive telemetry with Prometheus, Grafana, and ELK/Datadog. – FinOps & efficiency. Monitor and optimize infrastructure spend, architecting solutions that are both high-performing and cost-efficient. – Mentorship. Act as a force multiplier — set the technical standards for the DevOps team and guide software engineering squads. What We're Looking For – Orchestration. Deep, under-the-hood expertise in Kubernetes (EKS/GKE/AKS) and service meshes (Istio/Linkerd). – Provisioning. Expert-level mastery of Terraform; experience with Pulumi or Crossplane is a plus. – Automation. Proficiency in Python, Go, or Bash for building custom platform tooling. – CI/CD. Advanced knowledge of GitHub Enterprise — Actions, Runners, and API-driven automation. Signlabs Page 2 – Cloud. Strong experience with AWS (preferred), Azure, or GCP. – Security. Hands-on DevSecOps practice — secret management with Vault, image scanning, and policy enforcement via OPA/Kyverno. What Success Looks Like Month 1 You've audited our Terraform modules and set a roadmap for a unified, multi- region Kubernetes deployment strategy. Month 3 You've cut time-to-production for new services by 40% through standardized CI/CD templates and self-service infra provisioning. Month 6 The platform is a competitive advantage: developers deploy with confidence, infrastructure costs are optimized, and reliability (SLAs) is at an all-time high.
