About this role

The Information Security Operations Lead is responsible for the operational execution, oversight, and continuous improvement of the Bank’s cybersecurity program, ensuring alignment with regulatory requirements (FFIEC, GLBA, NIST CSF) and enterprise risk management objectives.

 

This role translates the Information Security Officer's (ISO) strategic direction into measurable, tool-driven security operations, including security monitoring, identity and access management (IAM), incident response, and control enforcement.

The Operations Lead serves as the primary accountable leader for day-to-day cybersecurity operations, overseeing analysts and engineers and ensuring the effective use of security platforms, including SIEM, IAM, endpoint protection, and vulnerability management tools.

The ideal candidate is technical and possesses at least seven years of experience in technology and security administration across large heterogeneous networks, including third-party entities. Additionally, as a senior member of the information security team, the role requires leadership skills to coach and mentor less experienced staffers. Information Security Operations Lead is expected to manage the team and execute the security strategy as directed by senior management.

 

This position requires strong written and oral communication skills, as well as the ability to convey detailed technical information in a manner comprehensible to individuals with varying levels of experience and skill. This role requires the ability to speak confidently in front of large groups and with corporate management, vendors, and service providers. The Information Security Operations Lead also contributes to the company's IT security strategy and roadmap.
