• Platform Support (Appian): Monitor the health and connectivity of self-managed Appian platform layers (Engines, Data Server, Kafka/Zookeeper data planes) utilizing the Appian Operator on Kubernetes.
• Infrastructure as Code (IaC): Maintain and update existing Terraform or CloudFormation modules to manage core AWS services (EC2, EKS, RDS, IAM, and VPCs).
• Security & Compliance Operationalization: Execute routine cluster updates, patch container vulnerabilities, and implement RBAC policies to ensure alignment with FedRAMP or NIST SP 800-53 security controls.
• Observability: Configure alerts, dashboards, and log streaming using tools like Prometheus, Grafana, or AWS CloudWatch to minimize downtime.

• Minimum of FIVE (5+) years of overall work experience.
• THREE (3+) years of professional experience in Cloud Kubernetes Operations, DevOps, or Site Reliability Engineering (SRE).
• Containerization: Strong hands-on experience using AWS Elastic Kubernetes Service (AWS EKS) (kubectl, managing namespaces, resource limits) and writing/modifying Helm charts.
• AWS & GovCloud Familiarity: Core knowledge of AWS foundational infrastructure with an understanding of navigating the operational constraints of secure or regulated cloud boundaries.
• Application Ecosystems: Familiarity supporting .NET application environments and an interest in or exposure to enterprise low-code platform topologies (like Appian or similar BPM engines).
