Role Overview
As a Sr. Enterprise Systems Engineer at Cboe, you will design, engineer, and deliver enterprise infrastructure solutions that underpin both internal operations and customer-facing platforms across our global exchange network. In this senior individual-contributor role, you will be expected to own complex initiatives end-to-end — from architecture through delivery — and to serve as a Subject Matter Expert in at least one major infrastructure domain.
You will maintain the reliability, security, and scalability of enterprise systems while resolving complex technical issues and driving continuous improvement. Your scope includes Windows Server, VMware, Azure, and Microsoft 365 platforms, with a strong emphasis on automation, observability, DR readiness, and SOX-compliance across regulated environments.
The ideal candidate brings a strong engineering mindset combined with a service-delivery orientation - someone who can own complex incidents end-to-end, and communicate technical decisions clearly to peers and other stakeholders across multiple time zones. This role is a key node in Cboe's follow-the-sun support model, requiring sound judgment, proactive communication, and a high standard for operational discipline.
