Hands-on experience with CI/CD, IaC (Terraform, CloudFormation), and modern DevOps practices.
Exceptional communication and presentation skills with the ability to influence both technical and non-technical stakeholders.

Preferred Experience

Experience with customer-facing roles in enterprise SaaS environments or consulting.
