System Design Engineer

Location: Bellevue, WA Job Type: Contract Work Model: Remote Schedule: 40 hours/week

System One is seeking an experienced System Design Engineer to support the development of advanced nuclear energy systems. This role is responsible for the design and integration of complex process and plant systems from conceptual design through final implementation. The ideal candidate has a strong background in thermal-fluid systems, process engineering, and multidisciplinary system integration.

Responsibilities

  • Design nuclear and industrial process systems and subsystems from concept through final design.
  • Develop and maintain mass and energy balance models to support system performance and design analyses.
  • Integrate results from thermal, structural, seismic, pipe stress, and heat transfer analyses into overall system designs.
  • Apply applicable industry codes and standards, including ASME, ANS, ASTM, IEEE, and NFPA.
  • Develop engineering documentation, including:
    • System Design Descriptions (SDDs)
    • Engineering Design Specifications (EDS)
    • Interface Control Documents (ICDs)
  • Support the development of design packages, including P&IDs, 3D models, and system drawings.
  • Coordinate closely with mechanical, civil, instrumentation & controls (I&C), nuclear, and other engineering disciplines.
  • Provide technical oversight of suppliers and support engineering design reviews.
  • Support system testing, validation, qualification, and commissioning activities.

Required Qualifications

  • Bachelor's degree in Chemical Engineering, Nuclear Engineering, or a related engineering discipline.
  • 10+ years of system design and engineering experience.
  • Strong knowledge of thermodynamics, fluid systems, heat transfer, and mechanical/process system design.
  • Experience developing and maintaining mass and energy balance models using Aspen HYSYS and/or Aspen Plus.
  • Experience reading, interpreting, and developing Piping & Instrumentation Diagrams (P&IDs).
  • Demonstrated experience integrating complex engineering systems across multiple technical disciplines.
  • Strong analytical, problem-solving, organizational, and communication skills.

Preferred Qualifications

  • Experience supporting advanced reactor or commercial nuclear power projects.
  • Familiarity with engineering design processes in highly regulated industries.
  • Experience supporting supplier management and multidisciplinary design reviews.
  • Working knowledge of configuration management and systems engineering principles.
