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

Essential Skills:

• A BS degree in engineering from an ABET accredited program

• 10 or more years of experience in the design engineering of instrumentation and controls engineering systems in a project team environment for heavy industrial plants, with a focus on integrated, detailed system design for new plants or replacements for existing plants
• Experience in providing technical support to nuclear plant projects - from design engineering, project planning, providing technical expertise associated with testing and operations, contract specifications, project oversight, successful project execution, and overall direction of complex nuclear projects
• Technically knowledgeable of available equipment and proven pre-engineered systems to execute systems design
• Experience with serving as firm/client liaison in a support or lead engineering role is desirable
• Experience in reviewing design drawings created by others

Valued but not required skills and experience:

• PE license

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.
