Senior Instrumentation And Controls Engineer Jobs in Illinois

This role offers a hybrid work arrangement. You'll spend three days a week in the office, giving you the flexibility to work remotely for two days.

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, small modular reactors (SMR) due to the increasing demand for electric power.  This is expanding our work in the Instrumentation and Controls Engineering group.  Due to this influx of work, Sargent & Lundy has a need for additional I&C Engineers.

This I&C position offers the opportunity to work on upgrading and modernizing nuclear power plants with the latest control technologies the industry offers.  You will be expected to both lead and support small and large controls projects with a focus on technical execution and effective Project Management.  These projects will require coordination with mechanical, electrical, and structural disciplines to bring the project to completion. You work will include investigating, troubleshooting, and resolving a wide variety of controls engineering issues, including the following:

• Develop Digital Systems Design -- PLC, DCS, Touchscreens, network switches and control systems.
• Prepare control system functional and implementation requirements and procurement specifications for nuclear plant control systems.
• Interface with the client to ensure proper project execution and client satisfaction.
• Prepare and review technical reports, calculations, and studies to present information in a clear and concise manner to meet client requirements.
• Manage resources/resource loading and develop estimates for task completion and budget development.
• Support the development of proposals.
• Prepare and review diagrams and drawings for new and upgraded controls solutions.
• Evaluate vendor bids from a technical perspective.
• Interface with vendors to perform document reviews, ensure equipment compliance with specifications and needs of the plant, and witness FAT performance on behalf of the client.
• Support implementation of the project at the client's facilities.

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

Essential skills and experience:

• BS or MS in Electrical, Mechanical, Chemical, or Nuclear Engineering from an ABET accredited program.
• 10 or more years of experience in I&C Design Engineering.
• Professional Engineering license is preferred.
• Ability to clearly communicate both in speech and written formats.
• Technically knowledgeable of available equipment and proven pre-engineered systems to execute systems design.
• Experience with serving as the firm's client liaison in a support or lead engineering role.
• Experience in reviewing design documentation.

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.
