Senior DevOps / Infrastructure Engineer (Athens-based)

About the company:

Senior DevOps Engineer joining a growing infrastructure team at Kiefer Tech. You will help standardize deployment pipelines, build observability from the ground up, and extend infrastructure-as-code across all services. The foundations exist; your job is to make them consistent, reliable, and scalable for enterprise production.

What you will do:

• Standardize CI/CD pipelines (GitHub Actions) and Helm charts across 10+ microservices

• Build centralized logging, metrics, and alerting

• Extend Terraform to cover full AWS infrastructure

• Improve deployment reliability: staging environments, rollback strategies, health checks

• Harden security: container scanning, secrets management, network policies

• Improve the local development experience (Docker Compose orchestration for all services)
