Deliver safe platform changes. Lead Citrix and Windows upgrades, image updates, and cloud migration work, including initiatives involving Oracle Cloud Infrastructure. Establish readiness criteria, deployment validation, and rollback procedures.
Strengthen security and configuration practices. Partner with security and infrastructure teams on vulnerability remediation, certificate lifecycle management, access controls, configuration baselines, and drift detection.
Provide technical leadership. Own substantial projects independently, explain architectural trade‑offs, review designs and automation, mentor engineers, and improve engineering practices across teams.
