Enterprise Security Architect

Enterprise Security Architect

The Opportunity:

Everyone knows security needs to be “baked in” to a system architecture—you actually know how to bake it in. You can identify and implement ways to harden systems and reduce their attack surface. What if you could use your cyber skills to lead the design and development of secure systems? We’re looking for a forward-learning cybersecurity thinker who can create solutions for Fortune 250 clients that will withstand even the most advanced cyber threats.

As a lead Enterprise Security Architect at Booz Allen Defy, you’ll support the growth, delivery, and continuous evolution of the company’s threat detection and response capability. This role combines deep technical credibility with the insight, communication, and commercial leadership required to advise complex organizations, lead multidisciplinary teams, shape target-state capabilities, and deliver measurable improvements in detection and response.

The successful candidate will be a broad cybersecurity practitioner with strong depth in detection engineering, endpoint security, security telemetry, log pipelining, data ingestion, and ETL. They will translate client problems into practical architectures, operating models, roadmaps, and implementation plans, serve as a trusted subject matter expert in proposals and client pursuits, and apply sound AI principles to emerging detection and response challenges with appropriate security, governance, and human oversight.

What You’ll Work On:

• Execute the vision, priorities, and delivery standards for the threat detection and response capability, aligned to client risk, business outcomes, and market needs.
• Build and maintain reusable methods, reference architectures, playbooks, accelerators, and points of view across detection engineering, endpoint, telemetry, and response.
• Coach and develop cybersecurity practitioners, technical leads, and emerging consultants and create an environment that values technical rigor, practical delivery, and clear communication.
• Lead or oversee cybersecurity engagements from problem definition through architecture, roadmap, implementation support, and executive readout.
• Assess current-state detection and response capabilities and define target states that improve visibility, triage, investigation, response, resilience, and measurable outcomes.
• Design and review detection engineering approaches, including use-case development, content lifecycle management, detection-as-code, testing, tuning, threat-informed coverage, and operational handoff.
• Develop practical approaches for endpoint security, XDR/SIEM integration, telemetry strategy, log routing, streaming, ingestion, data quality, pipeline resilience, and ETL or data transformation.
• Translate complex technical issues into concise recommendations for executives, business leaders, security practitioners, and engineering teams.
• Facilitate workshops and working sessions that bring together cybersecurity, IT, cloud, application, identity, network, data, operations, and business stakeholders.
• Identify and apply where AI, machine learning, generative AI, and agentic capabilities can improve detection, triage, investigation, threat hunting, engineering productivity, and response execution.
