Enterprise Security Architect, Lead

The Opportunity:

Security must be architected, not bolted on. You understand how to embed security into every layer of an enterprise system, from data pathways to identity flows, to network segmentation and cloud control planes. We are seeking an Enterprise Security Architect to design security solutions for clients with complex network, platform, and data‑protection needs that withstand advanced cyber threats. In this role, you will help define, enhance, implement, and maintain security solutions for one or more networks and technology platforms while guiding adherence to information security policies and procedures.

In this role, you will apply risk modeling and secure design methodologies to develop tailored controls for client and industry exposures, then translate those designs into practical architectures for network and application deployments. You will advise on security technologies and communicate security complexities clearly to technical teams, stakeholders, and senior management. You will partner with engineering teams, cybersecurity SMEs, cloud and platform owners, and business stakeholders.

You’ll assess current‑state environments, identify architectural gaps, evaluate emerging technologies, and build roadmaps that advance enterprise security maturity. This is an opportunity to shape hardened systems that support the mission and to learn from a team of experts while doing it.
