Senior Mechanical Engineer

Aplin is partnering with a leading industrial manufacturer to recruit a Senior Mechanical Engineer to support the execution of nuclear and critical fabrication projects. This is a hands-on role within a regulated environment where engineering decisions directly impact fabrication, compliance, and delivery.

This position requires a technically strong engineer who can operate with a high degree of independence in a code-driven, audit-ready environment.

Key Responsibilities

• Lead mechanical engineering execution for nuclear fabrication projects
  
  
• Develop and review fabrication drawings, calculations, and engineering packages
  
  
• Ensure compliance with ASME Section III, Section VIII, CSA, and customer specifications
  
  
• Support technical estimating, quoting, and risk evaluation
  
  
• Provide engineering support throughout manufacturing
  
  
• Participate in design reviews, audits, and inspections
  
  
• Resolve shop-floor technical issues and deviations in real time
  
  
• Support continuous improvement initiatives across engineering and production
  
  
• Mentoring and providing guidance to junior engineers

Required Qualifications

• Bachelor’s Degree in Mechanical Engineering
  
  
• Professional Engineer (P.Eng.) designation — required
  
  
• 10–15 years of experience in:
  
  
  • Nuclear manufacturing
    
    
  • Pressure vessel fabrication
    
    
  • Heavy industrial or engineered-to-order environments
    
    
• Strong, working knowledge of:
  
  
  • ASME codes (Section III and Section VIII)
    
    
  • Fabrication and welding processes
    
    
  • Manufacturing environments and shop-floor execution
    
    
• Proven ability to:
  
  
  • Work effectively in a regulated, compliance-driven environment
    
    
  • Produce clear, accurate, and audit-ready technical documentation
    
    
  • Communicate effectively across engineering, quality, and production teams

Role Context
This is not a design-only role. The successful candidate will be expected to work closely with fabrication teams, support projects from engineering through manufacturing and delivery, and operate in a fast-paced environment with limited ramp-up time.
