Deep Terraform experience managing infrastructure as code across multiple environments. Solid networking fundamentals: routing, subnetting, VPNs, firewalls, and IP schema design across hybrid environments. Experience with on-premises infrastructure: bare-metal servers, enterprise networking (Ubiquiti, Cisco, or similar), storage, and IDF/server room operations. Scripting and automation skills in Python, Go, or similar. Comfort working in environments where infrastructure issues have direct operational impact (manufacturing, broadcast, trading, healthcare, etc.).
