$118.02k - $180.31k

Sargent & Lundy

Description

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.

You will be involved in nuclear power plant systems design, including preparation or review of:

  • Modification packages for operating nuclear power plants

  • Functional mechanical drawings and/or drawings for nuclear power plant systems

  • Engineering analyses and evaluations to support modifications and operation of plant systems

  • Technical specifications and procurement documents for plant equipment

  • Vendor bid evaluations for plant equipment

  • Studies and options evaluations for modifications to operating nuclear power plants

In addition, you will have the opportunity to:

  • Develop engineering cost estimates for small to mid-sized client-requested work scopes

  • Visit client office and/or plant site locations to interface with the client and make presentations related to engineering tasks and status

  • Lead engineering project teams

Qualifications

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

  • BS or MS in Mechanical or Chemical Engineering from an ABET accredited program with academic coursework in thermodynamics, fluid mechanics, and heat transfers

  • PE license is beneficial, but not required

AI & Automation at Sargent & Lundy

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.
