Senior System Engineer

Role Overview

The Senior Systems Engineer is a hands‑on, operationally accountable role at the heart of Verifone’s Americas IT Infrastructure team. You will serve as a key technical contributor to Verifone’s VMware‑to‑KVM/Cloud Stack migration programme and broader platform operations — bringing depth across Linux, Windows, storage, and Dev Ops tooling while operating within a PCI DSS environment. This is a role for an experienced engineer who can independently own work streams, mentor junior team members, and drive cross‑team initiatives with limited supervision.

You will proactively identify issues, propose solutions, and deliver results that directly impact Verifone’s infrastructure reliability and compliance posture.
