Manage and lead engineering teams building endpoint security software: define and execute roadmaps, oversee SDLC and ISMS compliance, remove blockers, drive secure coding, coordinate with product and architects, recruit and develop staff, and manage budgets and operations.

Lead strategy, execution, and operational excellence for multiple security engineering domains. Build and develop leaders, deliver multi-year roadmaps, drive platform evolution, automation, vendor strategy, and cross-functional programs to reduce risk and scale secure operations.

Support cybersecurity engineering for a VA healthcare modernization project: secure AWS and hybrid environments, support RMF/ATO and compliance, configure and monitor AWS security services, produce SSPs/POA&Ms/SOPs, perform vulnerability assessments and DISA STIG hardening, integrate security into DevSecOps and CI/CD, and collaborate with stakeholders on security controls and remediation.

Lead enterprise strategy and engineering to defend against AI-powered threats. Design detection, prevention, and response architecture for adversarial AI, integrate controls into cyber tooling, build threat models, prototype defensive AI, and mentor teams while influencing leadership and vendor selection.

Lead and oversee system security engineering and certification activities for SAP/SCI systems. Chair cybersecurity working groups, assess designs for compliance with NIST/RMF and JSIG, provide risk management and accreditation support, assist program protection planning, and coordinate with approval authorities to obtain Authorization to Operate.

Lead security engineering efforts across classified AWS environments, driving RMF lifecycle activities, system hardening, vulnerability management, and A&A documentation (SSP, SAR, POA&M). Serve as technical liaison to engineering and leadership, translating vulnerabilities into mission risk and ensuring controls meet NIST 800-53 and DoD requirements.

Lead and deliver complex Palo Alto Networks-focused cybersecurity consulting engagements: design security architectures, run workshops and assessments, scope and support pre-sales, develop practice offerings, mentor consultants, and produce thought leadership while ensuring client objectives and quality delivery.

Build and maintain scalable data pipelines and data products to enable security and fraud detection. Implement ETL, data models, and distributed processing (Spark/Presto/Flink/Kafka) to centralize signals, support analytics and machine learning, and partner with security teams to improve detection and mitigation of fraud and account compromise.

Provide engineering-first customer support for security, privacy, and assurance tooling. Triage and resolve authentication and access issues, build automation and runbooks, maintain support tooling, and improve developer experience. Use Generative AI responsibly to accelerate triage, documentation, and automation while advocating for customers and collaborating with product and engineering partners.

Design, develop, and maintain Windows-focused PAM components including services, agents, and RDP handlers. Integrate with Windows APIs, authentication and privilege models, implement secure credential handling and policy enforcement, collaborate with backend teams, perform code reviews, and troubleshoot complex Windows OS and enterprise configurations.

Serve as the technical bridge between Product/Engineering and Customer Success to own onboarding, integrations, reference architectures, and troubleshooting for Zafran's cybersecurity platform. Influence product roadmap, advise R&D, and drive customer adoption and technical outcomes.

Lead technical discovery and design for enterprise customers, deliver demos and workshops, build architectures and POCs, influence sales strategy and product roadmap, enable partners, and create reference architectures and playbooks to support pre-sales and strategic deployments.

The fellowship provides military spouses and separating service members with cybersecurity training and hands-on experience through projects and vendor training, aimed at enhancing their security skills.
