The role focuses on ensuring the reliability, scalability, and performance of containerized infrastructure while collaborating with cross-functional teams to design and maintain complex systems for their cloud platform.
Responsibilities:
• 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.
Qualifications:
Required:
• Bachelor’s degree in computer science or a related field, or equivalent experience, typically 2 years in a Site Reliability Engineering, DevOps, or Systems Engineering role.
• Must be familiar with containerized technologies such as Kubernetes, container, and/or nerdctl. This includes the ability to deploy, manage, and scale containerized applications effectively.
• Intermediate experience implementing continuous integration and continuous delivery (CI/CD) tools and systems.
• Proficiency in programming languages such as: Shell scripting (Bash), and familiarity with YAML/JSON.
• Automation scripting with tools such as Ansible playbooks or similar imaging solutions.

• Strong written communication skills are essential, as well as the ability to create clear and informative documentation.
• Ability to work effectively across internal and external organizations.
• Flexibility to work off-hours for on-call duties. SREs are often responsible for maintaining the reliability and availability of systems outside of standard working hours, so the ability to respond to incidents and perform maintenance tasks as needed is required.
