• 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 (OpsCon) 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.
• Manage requirements traceability from stakeholder needs through design specifications, procurement documents, and verification activities using JAMA as the primary requirements management platform (IBM DOORS or similar experience considered transferable).
• Work across engineering disciplines to ensure effective integration of system components and subsystems, serving as the coordination layer between process, civil, EI&C, and safety teams.
• Perform work in accordance with TRISO-X quality assurance procedures to ensure engineering projects meet applicable nuclear industry quality standards (10 CFR Part 70, NQA-1, ISO/IEC/IEEE 15288).

• Bachelor's degree in Systems Engineering, Industrial Engineering, Mechanical Engineering, Nuclear Engineering, or other engineering-related discipline from an ABET-accredited institution required.
• Five years of experience in an engineering role required.
  • A master's degree in engineering or related field (may include a combination of experience obtained through an academic institution, e.g., design projects, research, or design teams, as well as professional experience) may be in lieu of two years of experience.
  • A Ph.D. in engineering or related field (may include a combination of experience obtained through an academic institution, e.g., design projects, research, or design teams, as well as professional experience) may be in lieu of three years of experience.
  • Previous experience at X-energy exceeding performance standards may be in lieu of years of experience.
• Proficiency using requirements management software (JAMA or IBM DOORS preferred).
• Experience managing Requirements Verification Traceability Matrices (RVTM) and performing requirements decomposition across multiple system levels.
• Proven ability to establish and maintain end-to-end traceability from stakeholder needs through design specifications and physical verification tests.
• Demonstrated ability to manage multiple concurrent facility subsystems across the complete design-to-operations lifecycle.
• Proven ability to identify and resolve interface conflicts before they become field issues.
• Experience participating in Engineering Change Control, governing modifications made during design, fabrication and installation phases.
• Proven ability to verify that final, physically installed hardware matches approved digital models and design requirements.
• Demonstrated ability to develop and execute V&V Plans.
• Experience creating test plans, test cases, and acceptance criteria for physical testing.
• Proven experience writing, reviewing, and maintaining engineering procedures and work instructions.
• Experience with JIRA or similar project management and workflow management tools.
• Ability to manage technical scope, coordinate multiple contributors, and track action items across multiple concurrent subsystems.
• Knowledge of System Lifecycle Processes (ISO/IEC/IEEE 15288:2023).
• Experience with technical risk assessments and management methodologies (FMEA, FMECA, HAZOP).

• INCOSE Certified Systems Engineering Professional (CSEP) or Associate Systems Engineering Professional (ASEP) – preferred but not required.
• Professional Engineer (PE) license in relevant discipline.
• Experience in nuclear fuel cycle facilities, small modular reactors (SMRs), or advanced reactor design.
• Prior experience working within NQA-1 or ISO 9001 quality management systems.
• Experience with nuclear regulatory compliance (NRC, DOE).
• Experience applying systems engineering in production/manufacturing environments or capital construction projects.
• Demonstrated success managing 5+ subsystems from design inception through physical commissioning.
