•Cybersecurity, Risk & Compliance: Ensure authentication and directory controls align with Pfizer policies, applicable regulatory requirements, and recognized security practices. Sponsor reduction of legacy protocols and insecure configurations, drive directory hygiene and vulnerability remediation, and maintain audit-ready evidence and sustainable business-as-usual controls.
•Operational Resilience & Incident Leadership: Ensure highly available global services with effective monitoring, disaster recovery, capacity management, service continuity, change governance, and 24x7 support. Provide senior leadership during significant incidents and problems, hold teams accountable for root-cause remediation, and convert operational insights into continuous improvement.
•Transformation & Delivery: Direct complex global programs such as directory modernization, domain controller upgrades, cloud migration of authentication services, passwordless adoption, and simplification or retirement of custom platforms. Resolve cross-functional dependencies, manage risk, and ensure programs deliver measurable business and security outcomes.
•Enterprise Partnership & Executive Communication: Partner with Cybersecurity, Infrastructure, Cloud Engineering, End User Computing, Application Development, Manufacturing, Business Integration, Compliance, Audit, and business stakeholders. Communicate service health, risk, investment needs, milestones, and decisions clearly to technical and executive audiences.
•Vendor & Ecosystem Management: Set the strategy for technology partners and managed service providers, including Microsoft and Ping Identity.
