OpenStack - Senior Software Engineer

Key Responsibilities

1. Debugging and Troubleshooting:

• Investigate and resolve complex software issues within OpenStack environments (particularly those running on Ubuntu), including networking, compute, and storage.
• Diagnose and troubleshoot problems related to Kubernetes container orchestration, including pod failures, service outages, and networking issues.
• Debug and analyze issues with Docker containers and their interaction with the underlying system.
• Analyze and resolve issues related to Ceph distributed storage, including data replication, performance tuning, and storage availability.
• Work on Octavia load balancers to troubleshoot L2/L3 networking issues and ensure reliable load balancing for cloud-native applications.

2. Incident and Problem Management:

• Lead incident resolution efforts for platform outages or performance degradation, coordinating across different teams to ensure swift recovery.
• Perform root cause analysis (RCA) and provide long-term fixes for recurring or critical issues.
• Document incident postmortems to prevent future occurrences and improve processes.

3. Performance Optimization:

• Analyze performance bottlenecks across the cloud stack, including OpenStack components, Kubernetes, and Ceph, and implement optimizations to improve reliability and efficiency.
• Optimize networking setups, including Octavia load balancers, to enhance cloud service delivery.
• Monitor and improve containerized application performance and scaling across Docker and Kubernetes clusters.
  

4. Cloud Platform Maintenance:

• Assist in upgrading and maintaining cloud infrastructure, ensuring that all components (Ubuntu, OpenStack, Kubernetes, Ceph, etc.) are kept secure and up to date.
• Participate in the deployment of software updates, security patches, and configuration changes in a controlled manner with minimal downtime.

5. Automation and Tooling:

• Build and maintain automation scripts for monitoring, troubleshooting, and resolving cloud platform issues, focusing on OpenStack, Kubernetes, Ceph, and Docker environments.
• Implement and optimize Infrastructure as Code (IaC) solutions to improve the deployment and configuration of cloud resources.
