Systems Engineer

Job Title:
Systems Engineer

This role is responsible for executing rigorous systems engineering processes to support the design, integration, verification, validation, and lifecycle management of complex nuclear systems from conceptual design through physical commissioning and operations turnover. Systems Engineer III applies INCOSE-aligned methodologies to manage multiple concurrent facility subsystems, ensuring all components work together effectively across the complete lifecycle, meet regulatory requirements, and are properly verified throughout the project.

This position plays a critical role in requirements traceability management (RVTM/VTM), interface control, configuration baseline management, verification & validation (V&V) planning and execution, procedure development, and enterprise architecture for asset management. Systems Engineer III owns the end-to-end lifecycle from design inception through as‑built verification and field commissioning for a set of assigned systems.

• Apply systems thinking and a holistic approach to solve problems, analyze and design systems, considering the interdependencies and interactions between various components across the entire facility lifecycle.
• Manage multiple concurrent facility subsystems across design‑to‑installation lifecycle, owning the functional, allocated, and product baselines for each system and ensuring seamless integration across disciplines.
• Lead and manage systems engineering lifecycle efforts surrounding:
• Operations Concept (Ops Con) development.
• Stakeholder and operational analysis.
• Requirements management.
• Functional design interface definition.
• System architecture development.
• Physical product definition, interface management, and change control.
• System verification and validation (V&V) planning and execution.
• Author, maintain, and manage Requirements Verification Traceability Matrices (RVTM/VTM) as the source of truth linking stakeholder needs, system requirements, design specifications, and physical verification tests across multiple subsystems.
• Develop, author, review, and maintain enterprise‑level engineering procedures that govern design control, configuration management, verification & validation, and engineering quality assurance processes across the organization.
• Create and maintain enterprise architecture documentation for asset management, including system baselines, interface documents, and configuration management records that support lifecycle control from design through operations.
• Govern cross‑functional Interface Controls (commonly ICDs) to manage critical dependencies between process equipment, structural elements, industrial automation networks, and facility utilities (e.g., HVAC, power distribution, chemical supply systems).
• Participate in the identification and monitoring of technical risks and the development of risk mitigation strategies using formal methodologies (FMEA, FMECA).
• Plan, develop, and execute comprehensive Verification & Validation (V&V) activities including:
• Design Verification Record preparation and closure.
• V&V Plan development and execution across all lifecycle phases.
• Test plan creation, review, and approval.
• Factory Acceptance Testing (FAT) planning, witnessing (in some cases), and approval.
• Site Acceptance Testing (SAT) planning and execution.
• Acceptance criteria definition and validation.
• Inspection, analysis, demonstration, and test method application.
• As‑built vs. as‑designed verification to confirm physical installations match approved digital models and design requirements
• Manage technical baselines across diverse architectural and engineering groups, ensuring that modifications to process equipment, utilities, automation systems, or structural elements are analyzed for systemic impacts before execution.
• Participate in multi‑disciplinary Configuration Control Board (CCB) to manage design variations, prevent scope creep, and ensure rigorous change management.
• Execute field engineering change control during construction and installation phases to govern modifications made during physical commissioning and prevent cascading system failures or interface conflicts.
