Chief Information Security Officer (CISO), US

TRG Screen•New York, NY

About The Position

We are seeking a strategic and hands-on Chief Information Security Officer (CISO) to lead and evolve the security function at TRG Screen, a global provider of market data and technology cost management solutions serving leading financial institutions including banks, asset managers, and hedge funds. The role spans both internal security — corporate IT policies, controls, and a remote workforce across the US, EU, UK, and India — and external security, protecting the products and solutions we deliver to clients. Reporting to the CTO and working closely with the Head of IT/Operations, the CISO will operate across a complex infrastructure encompassing AWS, Azure, and on-premises data centres. This is a high-impact role with genuine ownership — you will set the security agenda for a growing global business, with the mandate and senior leadership backing to build the function on your own terms. The timing is significant: we are actively embedding AI into our products and operations, making this an opportunity to define how we approach AI security from the ground up, in a sector where data protection and client trust are paramount.

Strong communication skills with the ability to engage both technical and non-technical stakeholders
Experience securing complex, multi-cloud environments (AWS and Azure) alongside on-premises data centre infrastructure
Awareness of AI security practices and risks, including securing AI-powered product features and governing internal AI tool usage
Based in or with easy access to the US East Coast or UK/Ireland, comfortable leading remote teams across the US, EU, UK, and India, and willing to travel periodically to our offices in New York, London, or Belfast
