Lead Mechanical Engineer 1 - Nuclear

Sargent & Lundy is a nuclear engineering, design, and licensing company supporting nuclear power and clean energy projects. The Lead Mechanical Engineer will design and evaluate nuclear power plant systems, prepare technical and procurement documentation, support client modifications, develop cost estimates, and lead engineering project teams while overseeing automation and AI-enabled engineering workflows.

Responsibilities:

• 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
• 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
• 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

Requirements:

• BS or MS in Mechanical or Chemical Engineering from an ABET accredited program
• A minimum of 10 years of experience in the power industry
• Working knowledge of codes, standards, and regulations that apply to mechanical engineering design of nuclear power plants
• 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
• 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
• We do not sponsor employees for work authorization in the U.S. for this position
• PE license is beneficial, but not required
• 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
