Job Type: Contract
Schedule: 40 hours/week

System One is seeking an experienced Instrumentation & Controls (I&C) Design Engineer to support the design and integration of advanced nuclear reactor systems. This role will focus on the development of Instrumentation & Control systems for nuclear island systems, structures, and components (SSCs), working closely with multidisciplinary engineering teams to deliver safe, reliable, and innovative engineering solutions.

• Develop and review system- and component-level engineering specifications and scopes of work.
• Perform engineering evaluations in accordance with nuclear codes, industry standards, licensing requirements, and NRC regulations.
• Specify instrumentation measurement techniques for advanced reactor technologies, including analysis of measurement range, response time, and measurement accuracy.
• Analyze and apply regulatory criteria and engineering standards to complex Instrumentation & Control system designs.
• Develop and review technical documentation, including:
  • System Requirements Documents (SRDs)
  • System Design Descriptions (SDDs)
  • Interface Control Documents (ICDs)
  • Engineering Design Specifications (EDS)
• Create and maintain engineering drawing packages including:
  • Piping & Instrumentation Diagrams (P&IDs)
  • Control system architecture drawings
  • Control logic and loop diagrams
  • Instrument installation drawings
• Develop integrated design packages for plant systems and components.
• Coordinate with multidisciplinary engineering teams, including mechanical, electrical, licensing, safety analysis, and systems engineering.
• Provide technical oversight of suppliers and subcontractors, including technical reviews of engineering deliverables.
• Support licensing activities and Safety Analysis Report development.
• Analyze engineering changes and evaluate impacts to interfacing systems while maintaining configuration and change control.
• Assist with system planning, testing, startup, commissioning, and qualification activities.
• Provide technical leadership and guidance to engineering teams as needed.
• Support continuous improvement initiatives and promote engineering best practices.

• Bachelor's degree or higher in Controls Engineering, Electrical Engineering, or a related engineering discipline from an accredited university.
• 10+ years of direct Instrumentation & Controls engineering experience (advanced degrees may be considered toward years of experience).
• Proven experience in instrumentation and controls system development, diagnostics, and the design and delivery of industrial I&C platforms.
• Demonstrated ability to design, integrate, and troubleshoot complex industrial control systems.
• Strong understanding of instrumentation measurement techniques, industrial automation, and control system architecture.
• Experience applying engineering codes, licensing requirements, and regulatory criteria to I&C system design.
• Ability to manage projects involving multiple competing objectives, technical challenges, and design constraints while balancing schedule and cost.
• Excellent analytical, technical writing, communication, and presentation skills.
• Self-starter with the ability to work independently and coordinate multidisciplinary engineering efforts.

• Experience with nuclear reactor safety systems or nuclear instrumentation system design.
• Familiarity with IEEE and IEC standards.
• Experience implementing design control processes in accordance with nuclear quality assurance programs such as 10 CFR 50 Appendix B and ASME NQA-1.
• Experience designing or supporting high-temperature industrial processes (400°C or greater).
• Experience developing or interpreting Process Flow Diagrams (PFDs) and Piping & Instrumentation Diagrams (P&IDs).
• Experience using CAD software such as AutoCAD, AutoCAD Electrical, or Solid Works.
• Experience supporting formal I&C startup testing, commissioning, or system validation.
• Previous experience in commercial nuclear, advanced reactors, power generation, aerospace, defense, or another highly regulated engineering environment.

• Travel: Up to 25%
• Work Environment: Standard office environment with occasional travel.
• Physical Requirements: Ability to sit or stand for extended periods and lift up to 25 pounds as needed.
