Cloud Infrastructure Engineer (Career Path → Senior Cloud Engineer / Security Engineer) $95,000 - $110,000 + Monthly Bonus I'm hiring again because our cloud and security practice continues to scale faster than expected. Over the past few years, we've doubled recurring revenue, expanded our project delivery team, and strengthened our cloud-first service model. We're a financially backed, growth-focused MSP serving SMB and mid-market clients across Chicago, and we've invested heavily in Azure, automation, security hardening, and standardizing how we deliver modern cloud environments.
