Instrumentation & Controls Engineer 3 - Nuclear

Sargent & Lundy•Warrenville, IL

1d•Hybrid

About The Position

This role offers a hybrid work arrangement, with three days in the office and two days remote. Nuclear Power is a carbon-free energy source. Our nuclear power generation clients are digitizing their existing power plants and building new nuclear power plants, including small modular reactors (SMRs), due to increasing demand for electric power. This expansion is driving growth in our Instrumentation and Controls Engineering group. Sargent & Lundy has a need for additional I&C Engineers to support this influx of work. This position offers the opportunity to utilize and expand your engineering background by digitizing nuclear power plants. You will work on a multi-discipline engineering team involved in nuclear power plant instrumentation and controls betterment projects, which involve a synergistic integration of electrical and mechanical engineering along with control theory. You will work with electronic process sensors, digital controllers, touchscreen displays, pumps, valves, heat exchangers, steam turbines, and reactors to improve the functionality of nuclear power plants. Responsibilities include preparing functional requirement and procurement specifications for instrumentation and controls equipment, preparing I&C engineering calculations, and preparing documentation for design input for drawing production, including cable block diagrams and schematics. You will also provide guidance as a mentor to less experienced nuclear instrumentation and control design engineers through mentoring, classroom-style technical sessions, and on-the-job training. Travel to client and vendor offices for design reviews and to plant site locations for project coordination and field verification of designs is also part of this role.

Requirements

A BS or MS degree in Electrical, Mechanical, or Chemical Engineering (from an ABET accredited program) with a strong academic background and coursework in analog and digital control systems is required.
A minimum of 3 years of engineering experience or a MS degree.
Excellent written and verbal communication skills.
Willingness or ability to solve problems using modern tools such as automation and AI to improve workflows, reduce rework, and deliver cost-effective designs.
Strong engineering judgment and verification of results.

Nice To Haves

Coursework in mechatronics is desired, but not required.
Programming or scripting (e.g., Python, MATLAB, advanced Excel) to automate calculations, design checks, reporting, or data transformation is valued but not required.
Additional learning, such as a minor, certificate, or other training in Computer Science, Artificial Intelligence, Software Engineering, or related fields that helps you apply automation or agentic AI to real engineering problems.
