Engineer IV, Plant & Process Design; Rotating Equipment

Engineer IV, Plant & Process Design (Rotating Equipment)

This role is responsible for designing and developing mechanical systems and components. It includes identifying requirements, conceptualizing system architecture and developing the layout through final design, performing process calculations, selecting and specifying equipment components ensuring they meet all technical specifications and program/project requirements. Additionally, this role oversees the implementation of rigorous, repeatable System Engineering processes, ensures technical integration, monitors risks, and provides system-level oversight and support.

The position is responsible for managing the entire effort to bring the system from initial requirements to a fully functional operational state in accordance with X‑energy design guides and standards and sound engineering principles.

• Lead the execution of the core tasks and responsibilities without close supervision and with latitude for independent judgment.
• Develop mechanical/physical system design concepts, design and support development of processes to create structures, systems, and components (SSCs). Planning/structuring scope for the analyses required to assess aspects of the SSCs to ensure they can perform their intended functions and meet design requirements and specifications.
• Provide independent reviews and acceptance reviews of engineering deliverables and data. Manage system development including planning, monitoring, and controlling of the complete engineering effort through all development life cycle phases.
• Manage design development leads and subcontractors to define system and subsystem functional and physical architecture, critical design parameters, and descriptive drawings.
• Apply applicable requirements, interfaces, design basis and criteria by coordinating with key stakeholders/systems engineers and identifying applicable industry codes and standards.
• Have a thorough understanding of the requirements contained within industry codes and standards and their intent.
• Direct the planning for the analyses required to assess all aspects of assigned SSCs to ensure they can perform their intended functions and meet all technical specifications and requirements.
• Supervise performance of computations utilizing hand calculations and analytical tools for structural, thermal, hydraulic, and other scoping calculations as required to ensure SSCs can meet all technical requirements.
• Oversee procured items and associated documentation for acceptance and verify compliance of procured services and material with contract specifications.
• Develop and manage implementation of engineering changes in accordance with approved procedures.
• Provide feedback and guidance to more junior team members with the execution of the core tasks and responsibilities.
• Lead small groups of engineers to solve complex technical problems and deliver high quality engineering work products on time and within budget.
• Serve as the technical authority on the design and analysis of Rankine cycle power conversion systems for nuclear power plants.
• Conduct and review detailed studies on turbine performance, condenser design, heat exchangers, and working fluid optimization.
• Collaborate with interfacing system owners to ensure proper thermal coupling and system integration.
• Participate in safety analysis, plant reliability, and plant performance evaluations.
• Provide input to equipment specifications, vendor evaluations, and procurement documentation.
• Assist in preparing documentation for regulatory submissions (e.g., NRC).
• Review and validate system simulations, including transient and steady-state analyses.
• Identify, collect, and document applicable requirements, interfaces, design basis and criteria by coordinating with key stakeholders/systems engineers and support identifying applicable industry codes and standards.
• Create and maintain CAD-generated engineering models.
• Support computations and analyses by others for thermal and hydraulic systems as required to ensure SSCs can meet technical requirements.
• Write and develop design documentation including, but not limited to, design basis…
