Head of Detection and Response

Job Description

I’m working with the global CISO of a world leading Hedge Fund in New York looking for an experienced cyber security professional to take on a “player-coach” role with a roughly 70/30 split between leadership and hands on technical work to build out and take full ownership of the company’s detection and response functions.

Naturally, within a hedge fund, the technical environment is complex and heavily customised. Therefore, suitable candidates will have plenty of experience in global, complex and fast environments that are constantly changing.

Responsibilities include:

\n
• Lead incident response, threat hunting, detection engineering, and forensics across the organisation.
\n
• Build and advance internal monitoring and auditing frameworks.
\n
• Develop and execute a vision for where our SecOps program goes next.
\n
• Act as a senior escalation point during incidents, communicating clearly with leadership and stakeholders.
\n
• Drive pragmatic adoption of AI-enabled approaches in detection/response (build vs buy, risks and controls).
\n

My client is looking for:

\n
• Demonstrated leadership in high-severity incidents with strong judgement and crisp communication.
\n
• Technical depth in threat hunting, detection engineering, incident response, forensics, and threat intelligence.
\n
• Experience building or running monitoring/detection programs (and improving signal quality over time).
\n
• Comfortable partnering with compliance and governance while maintaining operational effectiveness.
\n
• Thoughtful, practical approach to AI in security operations (not buzzword-led; not AI-averse).
\n

This role stands out to me as you’ll be trusted to lead when it matters most and your impact will be measured by stronger detection, faster response, and a more resilient security posture.

Hybrid out of NYC with three days onsite.
