Cybersecurity Engineer II

The Engineer II, Cybersecurity Engineering contributes to the delivery of secure command-and-control systems for nuclear and other critical infrastructure environments. Responsibilities span the execution of assigned system delivery packages within a V-Model framework and in collaboration with multidisciplinary teams, in accordance with established engineering processes and technical direction. Success in this role requires applying established standards, procedures, and templates with increasing independence while developing the systems engineering knowledge, technical competency, and professional judgment needed to execute increasingly complex system delivery efforts.

JOB RESPONSIBILITIES, DUTIES & CORE FUNCTIONS

• Support the translation of customer cybersecurity requirements into traceable component-level specifications using the Standard V-Model, in collaboration with Project Engineering Leads.
• Maintain requirements and traceability records for assigned scope, and flag gaps, conflicts, or ambiguities for resolution.
• Provide effort estimates for assigned tasks.

• Contribute to the design of cybersecurity architectures for AIM SCS and COTS-based command-and-control solutions, including network segmentation, access control, encryption, and secure communications, applying established designs and baselines traceable to NEI 08-09 and CIS benchmark controls.
• Develop and maintain design documentation for assigned scope, including network diagrams, configuration specifications, and cybersecurity control mapping matrices, with traceability to system requirements.

• Stand up, configure, and deploy platform environments of 20–30 Windows servers and workstations, virtualized infrastructure, Linux-based security appliances, network switches, and firewalls within an Active Directory domain, applying defined Group Policy-based security controls and hardening standards and following approved procedures and design documentation.
• Execute COTS solution integration tasks by performing system hardening, vulnerability analysis, patching, and documenting results.
• Diagnose and resolve integration issues using a systematic, analytical approach, escalating complex or cross-discipline issues as needed, and documenting resolution paths.
• Maintain configuration management records throughout the build, documenting changes and deviations to preserve a complete audit trail.

• Verify that assigned product feature sets meet functional and cybersecurity acceptance criteria prior to formal test completion.
• Support the development and execution of cybersecurity test procedures mapped through a Requirements Traceability Matrix (RTM) to validate compliance with applicable requirements.
• Support Acceptance Testing, performing vulnerability assessments and security scans, and documenting and tracking findings through disposition.

• 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.
• Assist with Site Acceptance Testing (SAT) in coordination with customer security, IT/OT, and operations staff, and communicate technical status and test results to the project team.
• Assist with training facility personnel and preparing turnover packages.
• Travel up to 25%.

• Capture lessons learned from system deliveries and recommend improvements to build, integration, and test procedures.
• Follow and help maintain team standards, playbooks, and technical library content to ensure consistency of engineering…
