## About the Role

Qualifications * 8+ years of experience designing, integrating, testing, or sustaining complex enterprise IT systems, including in classified environments. * Bachelorx27s degree in Systems Engineering, Computer Science, Information Technology, Engineering, or a related field. * Demonstrated experience managing system requirements, interfaces, dependencies, configurations, and technical documentation. * Experience integrating capabilities across network, infrastructure, cybersecurity, cloud, application, identity, or data domains. * Experience engineering capabilities for SCIF or other accredited classified environments, including multi-enclave systems and security boundaries. * Working knowledge of the Risk Management Framework (NIST SP 800-37 / 800-53) and experience advising senior leaders. * Active Top Secret Clearance (SCI eligibility) required.

## Description

Nice to Have: * Relevant systems engineering, architecture, or cybersecurity certification. * Experience integrating cross-domain solutions (CDS) into enterprise architectures. * Experience supporting Special Access Program (SAP) facilities, systems, or environments. * Experience designing or standing up network or security operations centers (NOC/SOC), including 24x7 coverage models.

Primary duties include: * Enumerate and document the technical baseline across geographically dispersed sites, including systems, services, interfaces, dependencies, security boundaries, and classified and unclassified network enclaves. * Translate mission and stakeholder needs into clear, measurable, testable, and traceable system requirements. * Develop current-state, transition-state, and target-state system designs that integrate network, infrastructure, cybersecurity, cloud, application, identity, and data capabilities. * Define system boundaries, interfaces, data flows, assumptions, constraints, and performance requirements across engineering disciplines. * Conduct technical analyses and trade studies addressing capability, interoperability, security, resilience, cost, schedule, risk, and lifecycle impacts. * Develop and execute integration, verification, validation, and acceptance plans demonstrating that delivered capabilities satisfy mission and operational requirements. *
Establish and maintain system configurations, technical baselines, architecture products, interface documentation, and engineering decision records. * Coordinate with engineering leads, operators, security personnel, and government stakeholders to identify and resolve cross-domain technical issues. * Develop automated methods for system provisioning, integration, testing, configuration validation, monitoring, compliance assessment, and recovery to improve consistency and reduce manual effort.

FOUNDATIONAL SKILLS * Systems engineering lifecycle principles and systems thinking. * Requirements analysis, decomposition, allocation, and traceability. * System architecture, integration, interfaces, and dependency management. * Verification, validation, test planning, and acceptance criteria. * Network, compute, storage, virtualization, cloud, identity, cybersecurity, application, and data fundamentals. * Reliability, availability, maintainability, scalability, resilience, and continuity of operations. * Configuration management, change control, technical baselines, and decision analysis. * Automation, scripting, configuration management, and infrastructure-as-code concepts. * Structured troubleshooting, root-cause analysis, technical documentation, and stakeholder communication.

Current Top Secret clearance with SCI-eligibility and SAP-eligibility are required for this position . Only applicants with a current security clearance will be considered. Applicants selected will be subject to a government security investigation and must meet eligibility requirements for access to classified information.
