Kubernetes Administrator

Guidehouse•Dc, DC

About The Position

This role focuses on Kubernetes operations, including maintaining, troubleshooting, and monitoring Kubernetes pods, services, and ingress controllers. It involves assisting development teams with deployment automation using Helm charts and CI/CD pipelines, supporting the Appian platform on Kubernetes, and managing core AWS services through Infrastructure as Code. The position also requires operationalizing security and compliance, configuring observability tools, and collaborating with other engineering teams.

Requirements

Bachelor's degree in IT, Computer Science, Engineering, or related field (or equivalent experience).
Five (5) years of overall experience, including three (3) years of professional experience in Cloud Kubernetes Operations, DevOps, or Site Reliability Engineering (SRE).
Strong hands-on experience using AWS Elastic Kubernetes Service (EKS) — kubectl, managing namespaces, resource limits — and writing/modifying Helm charts.
Core knowledge of AWS foundational infrastructure and an understanding of operating within secure or regulated cloud boundaries.
Familiarity supporting .NET application environments and exposure to enterprise low-code platform topologies (Appian or similar BPM engines).
General familiarity with Windows containers is sufficient; deep Windows Server administration is handled by the Senior Windows Server / Cloud DevOps Engineer.
Must be able to obtain and maintain a Federal or DoD Public Trust; approved adjudication required prior to onboarding.
Must be US Citizen or Green Card Holder.

Nice To Haves

Certified Kubernetes Administrator (CKA), AWS Certified CloudOps Engineer Associate, or AWS Certified DevOps Engineer Professional.
Hands-on experience with the Appian Operator on Kubernetes, including managing Appian Custom Resources (CRs) and monitoring data-plane components such as Apache Kafka.
Containerizing legacy .NET Framework applications into Windows containers, or working with cloud-native .NET Core/6/8 microservices on Linux containers (Windows-container experience is a plus, not a core requirement).
Declarative CD tools such as ArgoCD or FluxCD to sync and maintain cluster state directly from Git repositories.

Responsibilities

Maintain, troubleshoot, and monitor Kubernetes pods, services, and ingress controllers hosting Appian stateful workloads and .NET applications.
Assist development teams in packaging .NET applications (Linux or Windows containers) and deploying them via Helm charts and established CI/CD pipelines (e.g., GitLab, Jenkins, or GitHub Actions).
Monitor the health and connectivity of self-managed Appian platform layers (Engines, Data Server, Kafka/Zookeeper data planes) using the Appian Operator on Kubernetes.
Maintain and update existing Terraform or CloudFormation modules to manage core AWS services (EC2, EKS, RDS, IAM, and VPCs).
Execute routine cluster updates, patch container vulnerabilities, and implement RBAC policies aligned with FedRAMP or NIST SP 800-53 security controls.
Configure alerts, dashboards, and log streaming using tools like Prometheus, Grafana, or AWS CloudWatch to minimize downtime.
Partner with the Senior Windows Server / Cloud DevOps Engineer, who owns Windows Server production operations, so this role stays focused on container-platform operations.
