• Support DevOps activities, including CI/CD pipelines, infrastructure configuration, and environment setup

• Troubleshoot integration, performance, and deployment issues across client environments

• Contribute implementation feedback to improve solution patterns, documentation, and reusability

• Support early-life production stabilization and operational handover

What We Look for In You (Required Qualifications):
