About The Position

MANTECH seeks a motivated, career- and customer-oriented Cryptographic Systems Engineer to join its team in Linthicum Heights, Maryland. The role protects secure systems by providing expert engineering support for the Cryptographic Solutions Program and MPO's network security products. The engineer supports the development and integration of complex systems with embedded cryptographic capabilities, DoD risk management and authorization processes, requirements management, system documentation, reviews, and configuration baselining. The position is onsite and requires an active TS/SCI clearance with polygraph.

Requirements

Bachelor’s degree in a technical discipline and 14 years of relevant systems engineering experience, or experience in related cyber or software engineering fields; alternatively, 19 years of relevant experience in lieu of a degree.
Active TS/SCI clearance with polygraph.
Must be able to remain in a stationary position 50% of the time.
Must occasionally move about inside the office to access file cabinets, office machinery, and similar items.
Must frequently communicate with co-workers, management, and customers, including potentially delivering presentations, and exchange accurate information.

Nice To Haves

Hands-on experience with network security protocols, particularly EAP-TLS, MACsec, and IPsec.
Familiarity with cryptographic systems, COMSEC integration, Key Management Infrastructure (KMI), and secure network architectures.
Working knowledge of basic scripting, preferably Python, for test harness automation, data/log parsing, and functional checks on cryptographic devices; full-lifecycle software engineering experience is not required.

Responsibilities

Provide technical direction for development, engineering, interfacing, integration, and testing of complex hardware and software systems with embedded cryptographic capabilities.
Support system development and implementation planning by preparing and assessing Systems Engineering Management Plans (SEMPs) and System Integration and Test Plans (SITPs).
Support planning, execution, and test analysis for DoD Risk Management Framework (RMF) and Assessment and Authorization (A&A) processes.
Develop and maintain lightweight utility scripts, such as Python or Bash scripts, to run automated test harnesses, collect logs, and support hardware-level integration with cryptographic devices.
Derive and manage lower-level requirements from higher-level allocated requirements to ensure delivery of compatible, secure production systems.
Contribute to systems engineering documentation, including Systems Engineering Plans (SEPs), Initial Capabilities Documents (ICDs), and Interface Control Documents (ICDs) across red/black and secure enclave boundaries.
Coordinate action item resolution for Configuration Control Boards (CCBs), design reviews, program reviews, and test reviews requiring cross-discipline coordination.
Establish baseline definitions for systems and components under development to align hardware, software, and COMSEC/cyber engineering teams.
