We are looking for an experienced Senior Middleware Engineer with 4-6 years of experience in Kubernetes, Platform Engineering, Site Reliability Engineering (SRE), or DevOps. The ideal candidate will be responsible for designing, building, automating, securing, and operating enterprise-grade Kubernetes platforms across multiple environments, leveraging Amazon EKS, OpenShift, Terraform, GitOps, and modern cloud-native technologies.

Key Responsibilities

• Kubernetes Platform Engineering: Design, build, operate, and maintain Kubernetes platforms on Amazon EKS and OpenShift across development, test, acceptance, and production environments.
• Infrastructure as Code (IaC): Develop and maintain reusable Terraform modules to provision and manage infrastructure, including automated plan and apply pipelines.
• GitOps & Application Delivery: Implement and manage GitOps workflows using ArgoCD and Helm. Develop, maintain, and version internal Helm charts for platform components and add-ons.
• Node Provisioning & Autoscaling: Configure, operate, and optimize Kubernetes node provisioning and autoscaling using Karpenter, ensuring efficient resource utilization and platform reliability.
• CI/CD & Automation: Build and maintain CI/CD pipelines and infrastructure automation using GitHub Actions and scripting to improve delivery speed, consistency, and operational efficiency.
• Observability & Monitoring: Own platform observability using Datadog, including monitors as code, alert tuning, incident troubleshooting, and continuous improvement of monitoring and alert quality.
• Platform Security: Implement and maintain platform security controls, including HashiCorp Vault, External Secrets, IAM Roles for Service Accounts (IRSA), Kubernetes network policies, certificate management, and runtime security tooling.
• Platform Reliability & Operations: Troubleshoot complex platform issues, improve availability and performance, support incident response, and implement operational best practices.
• Platform Modernization: Participate in Kubernetes cluster upgrades, platform migrations, technology lifecycle management, and the adoption of new cloud-native capabilities.
• Documentation & Collaboration: Maintain technical documentation, operational runbooks, and platform standards while collaborating with development, security, and infrastructure teams.

Required Skills and Qualifications

• 4-6 years of experience in Kubernetes, Platform Engineering, SRE, or DevOps.
• Hands-on experience with Amazon EKS and/or OpenShift in enterprise environments.
• Strong knowledge of Kubernetes architecture, cluster operations, workload management, networking, and troubleshooting.
• Practical experience with Terraform, reusable modules, and automated infrastructure provisioning.
• Experience with GitOps practices using ArgoCD and Helm, including Helm chart development and maintenance.
• Hands-on experience with Karpenter or comparable Kubernetes node provisioning and autoscaling technologies.
• Experience building CI/CD pipelines using GitHub Actions.
• Experience with Datadog monitoring, alerting, observability, and infrastructure troubleshooting.
• Knowledge of cloud-native security practices, secrets management, IAM/IRSA, network policies, and certificate management.
• Familiarity with HashiCorp Vault, External Secrets, and Kubernetes runtime security tools.
• Experience with cluster upgrades, platform lifecycle management, and production operations.
• Strong troubleshooting, analytical, communication, and collaboration skills.

Preferred Qualifications

• Experience operating Kubernetes platforms across multiple environments and deployment stages.
• Knowledge of scripting and automation using Python, Bash, or similar languages.
• Familiarity with DevSecOps practices and automated security controls.
• Experience improving platform reliability, scalability, performance, and infrastructure cost efficiency.
• Exposure to incident management, SRE practices, and operational process improvement.

What Success Looks Like

• Reliable, secure, and scalable Kubernetes platforms across all environments.
• Standardized infrastructure provisioning and platform delivery through Terraform and GitOps.
• Efficient node scaling and optimized infrastructure utilization.
• Improved observability, actionable alerts, and faster incident resolution.
• Consistent application and platform deployments through automated CI/CD pipelines.
• Proactive platform modernization and continuous improvement of operational standards.
