Crypto Subject Matter Expert (SME)

Peraton is developing the next generation of missioncritical commandandcontrol and enterprise software capabilities supporting the U.S. Government's space communications infrastructure. Our teams deliver secure, resilient services that ensure trusted operations for complex, distributed mission systems.

As a Crypto Subject Matter Expert (SME), you will serve as the primary technical authority on cryptographic designs, PKI strategy, and identitycentric security capabilities across the platform. You will decompose systemlevel requirements into implementable cryptographic components, support architecture modeling within a Model-Based Systems Engineering (MBSE) environment, and guide engineering teams during development and testing. This role blends deep cryptographic expertise with handson system engineering to ensure secure, scalable, and missionaligned solutions.

What you'll do:

Decompose system and element level requirements into component cryptographic requirements that support overall system functionality and security objectives.
• Provide inputs to architecture teams and review system behavior captured within MBSE models to ensure accurate representation of cryptographic and identity services.
• Support the Product Manager in creating and refining the software backlog related to cryptographic functions, PKI capabilities, and identity management features.
• Guide Agile development teams during implementation and testing to ensure correct application of cryptographic protocols, certificate workflows, and Zero Trust principles.
• Serve as the program's technical authority on cryptographic design decisions, ensuring alignment with PKI strategy, system architecture, and mission security needs.

Required Qualifications:

• Associates degree and 14+ years of experience in a Systems Engineering related field; OR bachelor's degree in Computer Science, Computer Engineering, Cloud Computing, or related field and 12+ years of experience in a Systems Engineering related field; OR a master's degree in Computer Science, Computer Engineering, Cloud Computing, or related field and 10+ years of experience in a systems engineering related field; OR a Ph.D. and 7+ years of experience. Additional four (4) years of relevant experience will be considered in lieu of a degree.
• This position requires the candidate possess a minimum of Secret clearance with ability to upgrade to TS/SCI. The candidate must maintain the clearance
• Experience performing cybersecurity, cryptographic engineering, or information systems security engineering activities in a software or system engineering environment.
• Expertlevel understanding of Public Key Infrastructure (PKI) architecture and operations, including certificate lifecycle management and key management processes.
• Deep expertise in cryptographic protocols and technologies such as device endorsement, auditing, signing workflows, or certificate issuance.
• Experience implementing authentication and authorization technologies such as OAuth 2.0, JWT, RBAC, or ABAC.
• Proficiency in Python development with experience creating cryptographic automation such as key generation, certificate workflows, or PKI integrations.
• Knowledge of Zero Trust architectures and identitycentric security models.
• Experience reviewing or contributing to system architectures, interface definitions, or MBSE models, with the ability to align cryptographic requirements to system design.
• Experience supporting Agile development workflows, including backlog refinement, requirement clarification, or verification of implemented security features.

Desired Qualifications:

• Active TS/SCI
• Strong communication skills with the ability to explain complex cryptographic and system engineering concepts to crossfunctional teams.
• Demonstrated ability to collaborate effectively with system engineers, MBSE teams, product leadership, and software development teams.
• Strong analytical and organizational skills with the ability to prioritize technical work in a fastpaced development environment.
