About the Job

Requirements

  • A bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, Mathematics, Physics, or a related technical discipline is required.
  • At least 25 years of experience in applied cryptography, secure communications, embedded security, and high-assurance cybersecurity engineering is required.
  • An active Secret clearance or higher is required.
  • Demonstrated technical leadership in developing at least five Government-certified defense, intelligence, or national security products or systems requiring advanced encryption capabilities.
  • Deep understanding of cryptographic algorithms and protocols, secure key management and distribution, embedded cryptographic architectures, secure firmware and software implementation, hardware/software co-design for encryption systems, trusted computing and platform security, and Government certification security requirements and processes.
  • Experience with classified systems, mission assurance requirements, and secure system integration in complex program environments is required.
  • Ability to lead technical strategy, influence cross-functional engineering organizations, develop customer relationships, and engage with senior leadership is required.
  • A strong record of technical contribution through major program impact, architecture leadership, IRAD development that impacted program success, patents, publications, or enterprise-wide innovation is required.

Responsibilities

  • Serve as the enterprise technical leader for high-assurance and mission-critical encryption technologies across tactical and strategic applications.
  • Define and guide technical strategy for encryption solution architectures, secure communications, key management, and cryptographic modernization across defense and intelligence-focused programs.
  • Lead the design, assessment, certification, and deployment of high-assurance cryptographic solutions for tactical radios, datalinks, embedded mission systems, open architectures, secure networks, space systems, airborne platforms, and multi-domain operations.
  • Provide deep technical expertise in applied cryptographic systems; Government-approved cryptographic algorithms and implementations; COMSEC device architectures and key management; embedded programmable encryption solutions; secure boot, trusted execution, and hardware roots of trust; cross-domain and interoperable secure communications; anti-tamper and protection of critical program information; crypto modernization and transition planning; and post-quantum cryptography and future secure architectures.
  • Advise program teams on security architecture, cryptographic integration, technical risk, trade studies, and certification considerations.
  • Support business development and competitive business capture by shaping secure communications and encryption solutions for defense customers.
  • Partner with systems, software, hardware, programmable logic design, cybersecurity, and mission assurance teams to integrate encryption capabilities into complex platforms and product lines.
  • Guide technical approaches for interoperability, certification readiness, survivability, and lifecycle sustainment of encryption-enabled systems.
  • Conduct and lead independent technical reviews of encryption implementations, key management concepts, interface definitions, certification documentation, and secure communications architectures.
  • Mentor principal engineers, architects, and senior technical staff in developing high-assurance cryptographic expertise across the enterprise.
  • Represent L3Harris as a trusted technical authority with customers, government stakeholders, industry standards bodies, and internal executive leadership.

Desired Qualifications

  • A master's degree or PhD in a relevant technical discipline is preferred.
  • Recognized expertise in high-assurance encryption systems, Government-certified solutions, or high-assurance cryptographic implementations.
  • Experience with certification-driven development and engagement with government security stakeholders.
  • Knowledge of modernization of legacy COMSEC systems, secure interoperability approaches, and migration to next-generation cryptographic architectures.
  • Familiarity with TEMPEST, anti-tamper design, secure supply chain considerations, and protection of critical technologies.
  • Experience in post-quantum cryptography, zero trust for tactical environments, and secure communications in denied or contested environments.
  • An established reputation as a technical thought leader in defense encryption or secure communications.
