Senior Identity and Access Management (IAM) Specialist (Mainframe / Oracle exp highly desired)

LOB Overview:

• Global Information Security (GIS) is responsible for protecting bank information systems, confidential and proprietary data, and customer information. GIS develops the bank’s Information Security strategy and policy, manages the Information Security program, identifies, and addresses vulnerabilities and operates global security operations centers that monitor, detect, and respond to cybersecurity incidents. Within GIS, Identity and Access Management (IAM) is a security discipline that enables the right individuals to access the right resources at the right times and in the right context. IAM addresses the mission-critical need to ensure appropriate access to the resources across increasingly heterogeneous technology environments, and to meet increasingly rigorous compliance requirements.

Role Description:

• We are seeking a highly experienced and technically proficient Senior Identity and Access Management (IAM) Specialist to lead access provisioning initiatives across a complex enterprise environment. This role is critical to ensuring secure, compliant, and efficient access to systems and data, with a strong emphasis on enforcing least privileged access principles that eliminate excessive permissioning.

• The ideal candidate will bring deep expertise in IAM technologies and platforms—including Active Directory, Microsoft Azure, Amazon Web Services (AWS), and Mainframe, Oracle, SQL, and various file and storage collaboration systems, password secure controls including keys and tokens —and will be responsible for designing and implementing scalable access provisioning solutions to integrate IAM processes across cloud services. This is a hands-on technical leadership role that requires strategic thinking, cross-functional collaboration, and a commitment to continuous improvements in identity governance and access platforms and controls.

Responsibilities:

• Lead the design, implementation, and ongoing management of access provisioning solutions across enterprise platforms, ensuring alignment with security policies and regulatory requirements.

• Serve as the subject matter expert for Active Directory, Microsoft Azure, Amazon Web Services (AWS), and Mainframe, Oracle and SQL databases, file systems, and enterprise storage, with a focus on enforcing least privileged access.

• Develop and maintain access control policies, group structures, and role-based access models to support scalable and secure provisioning.

• Collaborate with application owners, infrastructure teams, and business stakeholders to define and implement access requirements for new and existing systems.

• Drive automation initiatives to streamline provisioning and de-provisioning workflows, integrating with identity governance platforms and HR systems and IAM controls.

• Conduct periodic access reviews, entitlement audits, and certification campaigns to ensure compliance and identify access anomalies.

• Investigate and remediate access-related incidents, working closely with cybersecurity and risk teams to address vulnerabilities and improve controls.

• Provide technical leadership and mentorship to junior IAM team members, fostering a culture of security-first thinking and operational excellence.

• Stay current with emerging IAM technologies, regulatory changes, and industry best practices to continuously enhance the access provisioning program.

• Prepare and present metrics, reports, and recommendations to senior leadership and audit teams regarding access provisioning effectiveness and risk posture.
