Mercury Systems is seeking an experienced Principal Systems Security Engineer to support the development of next-generation rugged, secure embedded processing solutions for mission-critical aerospace and defense applications.

In this role, you will work within the Processing Technology business unit, contributing to the design, integration, verification, and delivery of advanced secure computing products. You will play a critical role in developing and implementing security solutions that protect sensitive technologies against reverse engineering, unauthorized access, tampering, and exploitation.

The ideal candidate brings a strong background in systems engineering, embedded security, and anti-tamper technologies, along with experience developing secure processing solutions for Department of Defense (DoD) applications.

This position offers the opportunity to collaborate with multidisciplinary engineering teams and influence security architectures across multiple product lines and business units.

• Support the design, development, integration, verification, and delivery of rugged, secure embedded processing systems.
• Develop, analyze, and manage system-level requirements, ensuring alignment with customer specifications and security objectives.
• Apply systems engineering principles throughout the product development lifecycle, including system architecture, design, integration, testing, and verification/validation.
• Collaborate with hardware, software, firmware, and systems engineering teams to integrate security capabilities into embedded processing platforms.
• Support the development of secure processing solutions for DoD and other mission-critical applications.

• Design, develop, implement, and evaluate anti-tamper technologies to protect critical hardware, software, and intellectual property.
• Develop security solutions addressing reverse engineering, unauthorized access, exploitation, and system tampering.
• Apply hardware- and software-based security protections, including secure boot, encryption, and embedded security mechanisms.
• Conduct vulnerability assessments, threat modeling, and risk analyses to identify potential security weaknesses and attack vectors.
• Develop and recommend mitigation strategies to address identified vulnerabilities and security risks.
• Contribute to cybersecurity strategies, security architectures, and key management planning.
• Support the integration and validation of security controls within real-time embedded systems.

• Work within a matrixed engineering organization alongside systems engineers, Chief Engineers, program managers, and other technical stakeholders.
• Collaborate with business development, operations, supply chain, and leadership teams to support customer and program objectives.
• Provide technical guidance and recommendations related to systems security, embedded security architectures, and anti-tamper solutions.
• Participate in technical reviews and engineering discussions to ensure security requirements are incorporated throughout product development.

• Bachelor’s degree or higher in Engineering, Computer Science, Cybersecurity, or another STEM-related discipline.
• 6+ years of professional experience in Systems Engineering.
• Demonstrated experience applying systems engineering principles, including requirements development and management, system design, integration, and verification/validation.
