Cybersecurity Engineer Senior

MEANINGFUL WORK AND PERSONAL IMPACT:
The work you’ll do at GDIT will be impactful to the mission of USSTRATCOM. USSTRATCOM is a
Combatant Command responsible for strategic deterrence, nuclear operations, and enterprise IT services
essential to national security. It oversees Nuclear Command, Control, and Communications (NC3), Joint
Electromagnetic Spectrum Operations (JEMSO), Global Strike, and Missile Threat Assessments, working
closely with other Combatant Commands, Services, and defense agencies. SCITLS will be a key
component that will ensure mission success and the safety of the U.S. and its allies by providing 24/7 IT
services and network support for NIPRNet, SIPRNet, JWICS, and SAP/SAR environment.

You will play a crucial role in providing support in the following areas:
Translate mission objectives, operational needs, threats, and policy requirements into
measurable system security requirements and engineering specifications
Participate in systems engineering technical reviews, including system requirements
reviews, preliminary design reviews, solution design document reviews, test readiness
reviews, and operational readiness reviews
Integrate cybersecurity requirements throughout the system life cycle, including concept
development, requirement analysis, architecture design, integration, verification,
validation, deployment, sustainment, and disposal
Evaluate system designs for security, resilience, reliability, maintainability, interoperability,
scalability, and operational supportability
Develop or review system architecture products, including operational views, logical and
physical architecture diagrams, data-flow diagrams, trust-boundary, network diagrams,
interface control documents, and deployment diagrams
Develop and maintain cybersecurity artifacts, including system security plans, security
control implementation statements, architecture diagrams, risk assessments, remediation
plans, contingency plans, and security test documentation
Define security architecture patterns for identity and access management, privileged
access, encryption, key management, network segmentation, endpoint protection, logging,
monitoring, backup, recovery, and remote access
Design or recommend technical safeguards that protect data in transit, at rest, and in use,
consistent with mission and system requirements.
Conduct or support threat modeling, attack-surface analysis, misuse-case development,
and engineering risk assessments.
Strong technical background in system security, network security, cryptography, secure
architectures, firewalls, and DevSecOps environments
Proficiency in programming languages such as Java, C++, and Python, with hands on
experience in secure coding and automation.
Familiarity with cloud security (AWS, Azure, GCP), virtualization, identity management,
and security compliance frameworks.
Industry certifications such as CISSP-ISSEP and ASEP, GIAC, GCIH, CEH, or other
advanced cybersecurity credentials.
Demonstrated strength in problem solving, communication, documentation, and attention
to detail.
Experience designing secure architectures for enterprise systems, applications, and cloud
platforms.
