Staff Mechanical Engineer, Numenor (Reactor)

The role

The Staff Mechanical Engineer will serve as the technical owner for major mechanical systems within the reactor plant. You will set design direction from concept through build, test, and commissioning to drive systems into repeatable, scaled production.

What you will do

• Own the mechanical design basis for assigned systems including requirements, interfaces, margins, materials, and code selection.
• Make technical calls on design acceptability and escalate tradeoffs.
• Lead design reviews and drive systems through gate decisions.
• Perform and review stress, thermal, and fluid analyses.
• Take designs to hardware through procurement, vendor management, factory build, and assembly.
• Define test and qualification plans and support integrated testing and commissioning.
• Design for manufacture and repeatability.
• Work with systems engineering, safety, IC&E, quality, and supply chain.
• Mentor senior and junior engineers and review their designs.
• Lead root cause investigations on complex hardware issues and set mechanical design standards.

Required qualifications

• Bachelor’s degree in Mechanical Engineering or a related field.
• 8+ years of mechanical engineering on complex hardware, such as pressure systems, heat transfer equipment, mechanisms, or large structures.
• Experience as the technical owner of a major system, setting margins and making design decisions.
• Led mechanical scope on hardware from concept through build, test, and commissioning.
• Strong base in stress analysis, thermal design, materials, and pressure vessel and piping codes.
• Proficiency in CAD (SolidWorks, Creo, NX, or similar) and engineering drawing standards.

Nice to have

• Master’s degree in Mechanical Engineering or a related field.
• Experience with high-temperature, high-pressure systems, such as pressure vessels, heat exchangers, and piping.
• First-of-a-kind hardware experience in aerospace, power generation, oil and gas, or defense.
• Helium or other gas systems, including sealing, leak tightness, and rotating equipment.
• Precision mechanisms and actuators, plus the qualification testing that goes with them.
• Working knowledge of ASME pressure vessel and piping codes (Section VIII, B31.3).
• Design for manufacture and scaling from prototype to series production.
• Nuclear industry experience: commercial, defense, or national laboratory.
• PE license (Mechanical)

Benefits

• Competitive base salary
• Equity ownership
• Comprehensive medical benefits
• Unlimited PTO
• Free daily lunch and dinner provided onsite
• Generous PPE stipend

Before you apply

• Applicants must be legally authorized to work in the United States as a U.S. citizen or lawful permanent resident (green card holder).
