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.
