You will work on major process controls engineering projects for upgrades and modifications to nuclear power plants in the following areas:

• Digital Systems -- PLC, DCS, Touchscreen displays, network switches and control systems
• Functional Requirement and Procurement Specifications for instrumentation and control systems for nuclear power plants
• Process instrumentation replacement evaluation reports and nuclear modification packages
• Mechatronics, Control Systems for pumps, valves, heat exchangers, steam turbines and reactors to improve the functionality of the client’s plant
• Attend client meetings and perform site walkdowns to ensure the client is satisfied with our work product
• Provide guidance as a mentor in the development of less experienced nuclear instrumentation and controls design engineers

We do not sponsor employees for work authorization in the U.S. for this position. 

Essential skills and experience:

• BS degree in engineering from an ABET accredited program with a strong academic background and coursework in analog and digital control systems, systems engineering, mechatronics, or robotics is required.
• A minimum of 5 years of experience in design engineering for process control systems; Experience in design engineering for nuclear power plant control system is preferred
• Experience with controls system design including applications for low and medium voltage distribution systems and controls for equipment including but not limited to turbines, pumps, feedwater control, and data displays.
• Experience with power plant instrumentation and controls systems design for either BWR of PWR reactors, including DCS for turbine, control, feedwater control, and data display.
• Technically knowledgeable of available equipment and proven pre-engineered systems to execute systems design
• Experience in reviewing design drawings created by others.

In this role, we expect people to be willing or able to lead others who use modern tools:

• You are expected to lead others in taking engineering problems from issue to solution by setting expectations for using data and modern tools such as automation and AI to improve workflows, reduce rework, and deliver cost-effective designs.
• Leaders in these roles often direct automation and process-improvement work, for example, how teams automate calculations, summarize technical documents, or generate design documentation and guiding when and how AI or agentic AI tools are used while ensuring results are checked.
• Overseeing engineers who program or script (e.g., Python, MATLAB, advanced Excel) to automate engineering tasks, with review of automated outputs, is valued but not required.
• We also value additional learning, such as a minor, certificate, or other experience in Computer Science, Artificial Intelligence, Software Engineering, or related fields that enables effective oversight of automation and agentic AI-enabled engineering workflows.
