Job Description

You will be responsible for the deployment of containerized applications across a cluster of bare-metal servers, facilitating automatic scaling of containerized applications based on demand, and managing utilization of compute resources such as CPU, memory, and storage across the cluster.
Implementing monitoring solutions (e.g., Prometheus, Grafana) to track the health and performance of bare metal clusters and infrastructure components. You should be able to set up alerting mechanisms to detect and respond to issues proactively and recover from failures by restarting failed containers or reallocating workloads to healthy nodes.
Working closely with development and engineering teams to establish CI/CD pipelines for automating the deployment and rollout of Kubernetes services. Support seamless rolling updates allowing new versions to be deployed gradually while maintaining application availability.
Identifying performance bottlenecks in containerized environments and optimizing resource utilization through capacity planning, auto-scaling, and performance tuning.
Documenting processes, procedures, and best practices related to the platform operations and sharing knowledge with team members.
