DevOps Infrastructure Engineer / Systems Administrator

NMI•Schaumburg, IL

3h•$75,000 - $87,000•Remote

About The Position

We're looking for a curious and driven DevOps Engineer to join our Site Reliability Engineering (SRE) team. This is a great opportunity for someone early in their career who wants real ownership and exposure to enterprise-scale infrastructure. You'll work alongside experienced engineers to keep our global production and office environments running smoothly — a highly available WAN spanning multiple sites across the world. Day-to-day, you'll be involved in maintaining infrastructure, deploying configuration changes, troubleshooting platform issues, and contributing to the reliability of the systems that power payments for thousands of businesses. This is a fully remote role based in the US, with occasional travel (1–4 times per year) to company colocation facilities, fully covered by NMI. If you're near one of our offices, we encourage occasional in-person collaboration too. There is an on-call rotation as part of this role — you'll monitor infrastructure outside of core hours on a shared schedule and be expected to respond to issues promptly, either resolving or escalating them.
