MTS Product Security

Our Mission

Reflection is a research lab making intelligence open and accessible for everyone to use, customize, and build on. We build open models that let anyone control their intelligence and help shape the future of AI. Our mission: make intelligence open and accessible to all.

Role Overview

The MTS Lead for Product Security is responsible for building, scaling, and operating Reflection’s security program across the full breadth of the enterprise — from physical and data center infrastructure to cloud and neocloud environments, vendor ecosystems, and strategic growth activities. This lead serves as a senior partner to the CISO, translating the company’s long-term security strategy into an operating model that can withstand hypergrowth and the unique demands of a frontier AI company.

Sitting at the intersection of infrastructure security, enterprise operations, and strategic risk, this role is uniquely positioned to shape how Reflection understands and manages its security posture as it scales. The ideal candidate is both a strategic architect and a hands-on operator — equally capable of defining security standards for neocloud environments and standing up physical controls for a new data center deployment. They bring deep technical fluency across cloud, infrastructure, and AI compute environments, and the executive presence to represent Reflection’s security posture to customers, regulators, investors, and government stakeholders.

This is a high-visibility, high-impact role with broad organizational reach. Success requires the ability to build security programs from scratch, scale them through periods of rapid change, and maintain operational excellence across a complex, globally distributed technology footprint.
