Title:  Global Senior Security Manager

Location:  New York City, NY

ABOUT THE ROLE

We are seeking a seasoned security leader to partner with our CISO in protecting a complex, globally distributed financial services environment. This senior leader will drive transformation across Access Management, Network Engineering & Operations, and Security Governance, while championing an AI-first security strategy. You will work with the CISO at executive engagements and lead globally distributed teams to deliver security outcomes that enable business growth without compromising resilience.

KEY RESPONSIBILITIES

Security Leadership & Executive Representation

• Support CISO in key decision making and regulatory meetings — presenting risk posture, programme status, and strategic recommendations with clarity and confidence.
• Build, mentor, and manage high-performing, globally distributed security teams spanning multiple time zones and functions.
• Define and execute the enterprise security roadmap aligned with business strategy and applicable regulatory requirements (FCA, PRA, DORA, SOX, PCI-DSS).

Access Management

• Lead end-to-end transformation of Identity & Access Management (IAM) and Privileged Access Management (PAM), including strategy, tooling selection, and programme delivery.
• Drive implementation of an Identity Governance & Administration (IGA) framework — encompassing joiner/mover/leaver processes, role engineering, access certification, and policy enforcement.
• Oversee deployment and maturation of PAM controls, credential vaulting, just-in-time access, and session monitoring to eliminate over-privileged accounts across the enterprise.
• Establish access management metrics and KPIs reported to executive leadership and regulators.

Network Engineering & Operations

• Lead the Zero Trust Architecture (ZTA) transformation programme — defining principles, technology roadmap, and phased rollout across on-premises, cloud, and hybrid environments.
• Drive AI-augmented network and security architecture, leveraging machine learning for anomaly detection, automated policy enforcement, and predictive threat modelling.
• Build and operationalise a Network Operations (NetOps) operating model — defining governance, runbooks, escalation paths, and SLA frameworks for a globally resilient network.
• Own network security strategy including micro-segmentation, SASE, secure SD-WAN, and next-generation firewall policies aligned to Zero Trust principles.

Security Governance & Strategy

• Lead and coordinate internal and external security audits including SOC 1, SOC 2 (Type I & II), NIST CSF 2.0 and ISO/IEC 27001 — managing evidence collection, remediation tracking, and auditor engagement.
• Prepare the organisation for emerging AI regulatory frameworks: NIST AI RMF 1.0, NIST AI 600-1 (Generative AI Profile), EU AI Act, and ISO/IEC 42001 — developing controls, policies, and governance structures to demonstrate compliance.
• Maintain and mature the enterprise Information Security Management System (ISMS), ensuring policies, standards, and procedures remain current and auditable.

PREFERRED EXPERIENCE & QUALIFICATIONS

The ideal candidate will bring broad, deep expertise across cybersecurity disciplines, with demonstrated leadership in regulated financial services environments. Preferred experience includes:

Leadership & General

• 10+ years in cybersecurity with at least 5 years in a leadership role managing global, cross-functional teams.
• Proven track record of representing security at C-suite and board level, translating complex risk into clear business narrative.
• Experience in financial services or a similarly regulated industry (FCA, PRA, DORA, SOX, PCI-DSS).

AI Security & Innovation

• Familiarity with deploying AI security frameworks such as NIST AI RMF 1.0, MITRE ATLAS, and financial services AI governance standards.
• Practical knowledge of implementing AI-powered security tools to automate detection, response, and guardrail enforcement.
• Familiarity with AI model risk, LLM threat surfaces, data poisoning, prompt injection, and adversarial ML attack vectors.

Technology Solutions

• Familiarity with enterprise security tools.
• Broad exposure to endpoint protection, vulnerability management, CSPM, DLP, and email security platforms.

Certifications (Preferred)

• CISSP, CISM, or CRISC — one or more preferred.
• CCSP or equivalent cloud security credential; AI/ML security certification (e.g. GAISC) advantageous.

Other

• We are unable to sponsor or take over sponsorship of an employment visa.

Salary Range: For this role, we offer a salary of $150,000 - $210,000 depending on the skills and experience brought to the position. We encourage all candidates to apply and discuss the overall package with our recruitment team.
