• Infrastructure Automation: Build the IaC (Terraform/CDK) that turns network provisioning from hours into minutes


• Design network APIs: Create self-service automation that lets teams deploy infrastructure without manual intervention

• Cloud networking fundamentals: Strong understanding of VPCs, subnets, routing, firewalls, site-to-site connectivity


• CI/CD experience: GitHub Actions or similar—automation includes your own deployment pipelines


• Ownership mentality: You don't wait for someone to tell you what to fix. You identify problems and solve them.


• Linux/Bash comfort: You're comfortable in terminal environments and shell scripting


• Docker proficiency: Containerization is second nature


• Professional proficiency in English

Bonus Qualifications

• Cloud certifications (AWS, GCP, or equivalent)
