- Monitor and tune the environment for performance and cost
- Evaluate new tools that improve reliability, scalability and security

What you’ll bring

- 8+ years in cloud engineering or architecture, with deep AWS experience (EKS, EC2, S3, Lambda, RDS, VPC, IAM, CloudWatch)
- Robust scripting in Python and/or Bash
- Hands‑on experience with Terraform or Ansible
- Containers and orchestration: Docker, ECS, Kubernetes
- Linux and Windows administration and troubleshooting
- A clear communicator who can explain technical issues and support users through them
- AWS certifications are a plus
