Infrastructure Engineer – Chicago-; Remote

We’re working with a profitable, established SaaS company in Chicago that is hiring a hands-on Infrastructure Engineer to take ownership of a hybrid environment (colocation + AWS).

This is not a Dev Ops or Kubernetes-heavy role.

This is for someone who has actually:

• Managed Linux servers in production
• Updated firewall firmware confidently
• Worked inside a physical data center
• Managed VPNs and firewall policies
• Owned real infrastructure — not just CI/CD pipelines

The environment includes:

• Physical and virtual Linux servers (Ubuntu)
• SQL Server
• Storage systems
• AWS supporting a startup product migration

You’ll be the primary day-to-day infrastructure owner working closely with leadership. This is a lean team where you’ll wear multiple hats and have real impact.

We’re looking for someone who is:

• Calm under pressure
• Organized and pragmatic
• Comfortable switching between firewalls, servers, and AWS
• Not overly theoretical — someone who’s “lived in the world”

Must live in the Chicago metro area (occasional data center access required).
