Position Summary

The Information Systems Security Engineer serves as the OT Security Engineer for assigned USCG SFLC Operational Technology and provides the engineering half of the cybersecurity mission on this task order. Where the ISSOs own authorization and compliance, this role owns design: security requirements, defense-in-depth architecture, segmentation and boundary protection, and technical mitigation strategies that reduce risk without breaking operational capability.

The position works across acquisition, engineering, and sustainment activities, from design reviews and change control boards through DevSecOps pipeline support, and provides independent cybersecurity engineering assessments of USCG C5ISR acquisition program deliverables.

Key Responsibilities

• Serve as the OT Security Engineer (ISSE) for assigned SFLC Operational Technology, providing cybersecurity engineering input, recommendations, and implementation assistance.
• Design and develop security requirements and defense-in-depth solutions that reduce cybersecurity risk while maintaining operational capability and compliance with DHS, USCG, and DoD policy.
• Support architecture-level and implementation-level engineering activities, maintaining a system-wide view of cybersecurity functions and requirements, and recommend risk mitigation at the architecture, design, and implementation levels.
• Evaluate newly identified threats and vulnerabilities affecting assigned OT, determine the need for additional safeguards, and recommend technical mitigation and implementation strategies.
• Assess proposed changes to assigned OT, operating environments, and mission requirements for impacts to cybersecurity architecture, security requirements, and continued compliance; recommend technical mitigations.
• Participate in acquisition, engineering, and system development activities including program and design reviews, Concept of Operations (CONOP) working groups, change control boards, technical exchange meetings, technical discussions, and trade studies.
• Identify cybersecurity integration issues arising from new or modified systems within existing SFLC infrastructure and recommend mitigation or resolution options that preserve security, interoperability, and operational capability.
• Apply cybersecurity and systems engineering principles and industry best practice to the design, development, integration, and implementation of security requirements, including secure architecture, secure design, software engineering methodologies, defense-in-depth, and secure coding techniques.
• Provide cybersecurity engineering input to development and engineering teams responsible for design, development, integration, modernization, and upgrade of assigned OT, including legacy OT.
• Interface with Government stakeholders to communicate cybersecurity requirements, technical risks, and mitigation options, and explain their impacts on system performance, operational capability, cost, and schedule in support of Government risk-management decisions.
• Design and evaluate cybersecurity requirements for trusted relationships and interconnections between assigned OT and external systems or architectures; recommend safeguards to protect information exchanges.
• Provide engineering support for the design of systems and networks spanning multiple enclaves or differing information protection requirements, and recommend security architecture, segmentation, boundary protection, and information-flow controls.
• Evaluate current and emerging cybersecurity technologies, threats, vulnerabilities, and best practices applicable to assigned OT and provide technical recommendations to improve resilience.
• Provide cybersecurity engineering assessments of USCG Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance, and Reconnaissance (C5ISR) acquisition program deliverables in support of Independent Verification and Validation (IV&V), assessing requirements, architectures, standards, technical feasibility, and engineering content, and reporting findings and recommendations to the Government.
• Support DevSecOps activities for assigned OT, including cybersecurity engineering support for security dashboards and development of technical recommendations for vulnerability guardrails and thresholds for software and applications.
• Provide status reporting to the Program Manager and ISSM as required. [NOTE: unlike the four other labor CLINs, the SOW does not specify bi-weekly reporting or a monthly briefing for this position. Confirm the Government's expectation.]
