Senior System Security Engineer (SSE)

Bachelor's degree in Systems Engineering, or a related Science, Engineering or Mathematics field, plus a minimum of 5 years of relevant experience; or Master's degree, plus a minimum of 3 years of relevant experience.

Clearance Requirements:

Ability to obtain a Department of Defense Secret security clearance is required at time of hire. Applicants selected will be subject to a U.S. Government security investigation and must meet eligibility requirements for access to classified information. Due to the nature of work performed within our facilities, U.S. citizenship is required.

A successful candidate will possess practical knowledge of vulnerabilities and countermeasures across embedded systems, including microcontrollers, FPGA-based systems-on-chip (SoCs), ASICs, and workstation-grade single-board computers. GDMS is equally interested in physical and virtual threat vectors.

The  Systems Security Engineer independently performs assigned security analysis, requirements, design, and verification work for subsystem and component-level elements within U.S. weapon systems. The role works under senior technical direction while collaborating with hardware, software, systems, customer, and security-assessment teams.

Primary Responsibilities

• Develop and maintain assigned subsystem or device security requirements by eliciting, deriving, allocating, and tracing customer and system requirements.
• Evaluate proposed and existing system architectures for reverse-engineering and cyber-exploitation vulnerabilities.
• Perform security-focused analysis and support coordination with Government assessment laboratories and internal security red teams.
• Document vulnerabilities, threats, and countermeasure recommendations in white papers and attack-countermeasure analyses.
• Develop system-level security design artifacts and requirements that address identified vulnerabilities in U.S. weapon systems.
• Develop and execute test plans for functional verification, including CPU, interconnect, eFPGA, power and clock-domain isolation, and provisioning-state transitions.
• Perform hands-on integration, test development, execution, troubleshooting, and results analysis.
• Support ASIC package and Development Kit design activities with external suppliers.
• Contribute to CI/CD test environments that enable automated hardware and software testing.
• Prepare technical material for customer and Government design reviews and participate in those reviews.
• Participate in system architecture, design, development, verification, and product-release activities.
• Communicate complex technical concepts clearly in writing to support proposals, engineering decisions, and new product opportunities.
• Contribute to product ideas, proposals, industry working groups, and security recommendations for applicable standards, policies, and procedures.
• Identify opportunities to improve engineering workflows, test automation, and AI-enabled analysis.

What Sets You Apart

• More than five years of demonstrated embedded-systems security design experience; DoD embedded-systems security experience is preferred.
• Experience with ASIC or SoC design and verification, particularly system-level security architecture and integration.
• Strong knowledge of cryptographic algorithms, their appropriate use, implementation vulnerabilities, and countermeasures.
• Strong understanding of hardware and software attacks and vulnerabilities, including the ability to evaluate mitigation approaches and residual risk.
• Strong understanding of computer hardware and software architectures, including CPUs, FPGAs, operating systems, and user-space application runtime environments.
• Ability to document complex technical concepts clearly for technical and general audiences.
• Strong analytical, problem-solving, and collaboration skills.
• Experience working with external customers or technical partners to resolve engineering requirements.
