Responsibilities

• Translate customer cybersecurity requirements into traceable component-level specifications with Project Engineering Leads; maintain requirements and traceability records, flag gaps or conflicts, and provide task effort estimates.
• Contribute to cybersecurity architectures for AIM SCS and COTS-based command-and-control solutions, including network segmentation, access control, encryption, and secure communications, using established designs and baselines traceable to NEI 08-09 and CIS benchmark controls.
• Develop and maintain design documentation, including network diagrams, configuration specifications, and cybersecurity control mapping matrices, with traceability to system requirements.
• Stand up, configure, and deploy platform environments comprising 20–30 Windows servers and workstations, virtualized infrastructure, Linux-based security appliances, network switches, and firewalls within an Active Directory domain.
• Apply defined Group Policy-based security controls and hardening standards, following approved procedures and design documentation.
• Integrate COTS solutions by performing system hardening, vulnerability analysis, and patching, and documenting results.
• Diagnose and resolve integration issues systematically, escalate complex or cross-discipline issues as needed, and document resolution paths.
• Maintain configuration management records during builds, documenting changes and deviations to preserve an audit trail.
• Verify assigned product feature sets against functional and cybersecurity acceptance criteria before formal test completion.
• Support development and execution of cybersecurity test procedures mapped through a Requirements Traceability Matrix to validate compliance with applicable requirements.
• Support Acceptance Testing by performing vulnerability assessments and security scans and documenting and tracking findings through disposition.
• Support onsite customer deployments, including physical installation, network commissioning, Active Directory integration, and system configuration under site-specific cybersecurity commissioning procedures.
• Assist with Site Acceptance Testing in coordination with customer security, IT/OT, and operations staff; communicate technical status and test results to the project team.
• Assist with training facility personnel and preparing turnover packages.
• Capture lessons learned and recommend improvements to build, integration, and test procedures.
• Follow and help maintain team standards, playbooks, and technical library content.
• Build proficiency in nuclear regulatory and cybersecurity standards through experience, training, and mentoring.
• Perform other duties as required.
