As a Containers Platform Engineer at CSIT, you will design, deploy, and support container orchestration platform services that power mission-critical workloads across on-premise networks. You will join the Runtime Platforms team - responsible for delivering secure, reliable, and scalable container services that enable other CSIT engineers to deploy application workloads efficiently while maintaining strong security and compliance standards. Our team operates a multi-tenanted Kubernetes provider platform and it has included many enhancements aimed to improve developers' productivity. These include 3rd-party technologies as well as bespoke workflow enhancements.

Responsibilities

• Design and enhance Kubernetes provider platforms and supporting infrastructure to improve scalability, reliability, and developer experience.
• Automate and simplify Kubernetes clusters lifecycle management, upgrades, and observability workflows.
• Implement monitoring and alerting systems using tools such as Prometheus, Grafana, or Elastic Observability to meet service-level objective (SLOs).
• Collaborate with security teams to integrate and enforce security controls and compliance requirements within the container platform.
• Work with application teams to improve platform usability, streamline onboarding, and reduce operational toil.
• Respond to incidents and perform post-incident reviews, driving continuous improvement and operational excellence.
• Contribute to the reliability engineering culture, fostering shared responsibility for system availability and performance.

Requirements (Minimum Qualifications)

• A degree or professional qualification in Computer Engineering, Computer Science or related field
• Strong programming or scripting experience (e.g. Git, Terraform, Javascript, Python, or Bash)
• Good understanding of Linux systems, containers, and networking fundamentals.
• At least 1-3 years of hands-on experience operating or managing Kubernetes clusters in production environments.
• Familiarity with CI/CD pipelines, infrastructure-as-code, and configuration management (e.g. Terraform, Ansible, Helm).
• Experience implementing observability and monitoring in large-scale systems.

Good to Have

• Knowledge of Kubernetes security concepts such as RBAC, admission controllers, and policy enforcement.
• Experience with GitOps workflow and deployment tools (e.g. ArgoCD, Gitlab Runner)
• Understanding of service mesh technologies (e.g. Istio)
• Exposure to reliability engineering practices, including SLOs, error budgets, and capacity planning
• Familiarity with cloud platforms (AWS, GCP or Azure) and hybrid infrastructure architectures
• Knowledge of networking protocols (HTTP, TCP, DNS) and troubleshooting tools
• Passion for open-source technologies
