The Senior Engineer, Cybersecurity Engineering owns the end-to-end delivery of secure command-and-control systems for critical infrastructure environments. Responsibilities span requirements, design, integration, validation, and deployment within a V-Model framework, working across multidisciplinary teams. Success in this role requires both disciplined systems engineering and deep technical expertise.
JOB RESPONSIBILITIES, DUTIES & CORE FUNCTIONS
Requirements Definition & Analysis
Translate customer cybersecurity needs into traceable system-level and component-level specifications using the Standard V-Model, while collaborating with Project Engineering Leads.
Contribute to engineering cost estimates based on project requirements and communicate requirements-related issues and risks clearly to program leadership and customers.
System Design & Architecture
Design cybersecurity architectures for AIM SCS and COTS-based command-and-control solutions, encompassing network segmentation, access control, encryption, secure communications, and integration of physical security subsystems, with all design decisions traceable to applicable NEI 08-09 and CIS benchmark controls.
Architect platform environments of 20–30 Windows servers and workstations within an Active Directory domain—defining Group Policy-based security controls, virtualized cluster layouts, storage systems, Linux-based security appliances, network switches, and firewalls.
Produce and maintain design documentation—including virtual and network design plans, network architecture diagrams, configuration specifications, and cybersecurity control mapping matrices—with full traceability to system requirements.
Integration & Build
Stand up, configure, and deliver environments of 20–30 servers and workstations within an Active Directory domain.
Perform server and network deployment through the entire product delivery lifecycle to prioritize deliverables, validate product feature sets, and maintain schedule and budget alignment.
Execute COTS solution integrations by applying system hardening, vulnerability analysis, documentation, and patching.
Bring systematic, analytical thinking to the diagnosis and resolution of integration issues drawing on creative and innovative problem-solving and documenting resolution paths.
Maintain configuration management records throughout the build, documenting all decisions, changes, and deviations to provide a complete audit trail.
Verification & Validation
Verify product feature sets to confirm that functional and cybersecurity capabilities meet acceptance criteria prior to formal test completion.
Collaborate on development and execution of cybersecurity test procedures mapped through a Requirements Traceability Matrix (RTM), validating component and system-level compliance with all applicable requirements.
Support Acceptance Testing, conducting vulnerability assessments and security scans, dispositioning all findings.
Onsite Customer System Turn-Up & Support
Support onsite deployment at customer sites performing physical installation, network commissioning, Active Directory integration, and system configuration in accordance with site-specific cybersecurity commissioning procedures.
Conduct Site Acceptance Testing (SAT) in coordination with customer security, IT/OT, and operations staff —to diagnose and resolve site-specific integration challenges in real time and communicate technical status, test results, and issue dispositions to applicable stakeholders.
Train facility personnel on system operation, cybersecurity maintenance, and configuration management practices. Deliver thorough turnover packages.
Travel up to 25%.
Lifecycle Support & Continuous Improvement
Drive continuous improvement by capturing lessons learned after each system delivery and translating findings into updated design standards, integration procedures, and test methodologies; share knowledge across the organization to ensure consistency of engineering processes and…
