Principal Cloud & Kubernetes Engineer

InterSystems powers some of the world's most mission-critical healthcare, financial services, and data platforms. Our technology runs where reliability, security, and performance are not optional, and where platform engineering has a direct impact on clients and the people they serve. As Managed Services and SaaS continue to modernize, Kubernetes is becoming a core foundation for how we deliver resilient, automated, and scalable services globally. This role offers the opportunity to help shape that platform at a meaningful scale: building the engineering patterns, automation, reliability practices, and operational discipline that will support the next generation of InterSystems cloud and managed services capabilities. This is a chance to do deep technical work that matters: modern cloud-native engineering, real production responsibility, and the ability to influence how a global technology company evolves its service platforms. Role Overview We are seeking a Principal Kubernetes Engineer to serve as a senior hands-on technical leader for the build, operation, automation, and continuous improvement of InterSystems Kubernetes-based managed services and SaaS platforms. This role is intended for an engineer who has deep production Kubernetes experience and can lead complex implementation work across hybrid, private cloud, and public cloud environments. The Principal Kubernetes Engineer will work closely with Kubernetes architects, platform leadership, DevOps, Site Reliability Engineering, application, security, and infrastructure teams. The role is more experienced than a Senior Kubernetes Engineer and is expected to own the most complex engineering work, set implementation standards, guide other engineers, and translate architecture into reliable production platforms. This role is not primarily a people-management position. It is a principal individual contributor role for a hands-on engineer who can operate at senior depth, lead technical execution, mentor others, and drive platform Key Responsibilities Principal-Level Platform Engineering Lead complex Kubernetes platform engineering initiatives across public cloud, private cloud, and on-premises environments. Translate reference architectures and platform standards into production-ready implementation patterns. Own advanced cluster lifecycle activities including provisioning, upgrades, patching, node strategy, workload placement, resource governance, and operational readiness. Guide engineering decisions for EKS, AKS, GKE, Rancher, Spectro Cloud, or equivalent enterprise Kubernetes platforms. Act as a senior technical escalation point for Kubernetes platform design, operations, automation, and incident resolution. Advanced Kubernetes Operations Lead troubleshooting of complex Kubernetes failures involving control plane behavior, node health, CNI issues, ingress, storage, certificates, DNS, workload scheduling, resource pressure, and cluster degradation. Drive root cause analysis and permanent corrective actions for recurring platform issues. Establish operational runbooks, health checks, upgrade playbooks, and incident response practices for Kubernetes environments. Improve platform reliability through proactive monitoring, capacity analysis, error reduction, and operational standardization. Participate in production support for mission-critical managed services and SaaS workloads. Automation, GitOps, and Infrastructure as Code Lead development of reusable automation using Terraform, Helm, GitOps, CI/CD pipelines, and scripting languages such as Python, Bash, or Go. Define implementation-level standards for Terraform modules, Helm charts, Kubernetes manifests, deployment pipelines, and configuration management. Drive GitOps-based delivery using tools such as Argo CD, Flux, or equivalent platforms. Reduce manual operational work through repeatable, tested, version-controlled automation. Ensure platform changes are reviewed, validated, documented, and deployed through controlled…
