Turbomachinery Design Engineer II

The role

You will own the mechanical design of turbomachinery components and assemblies for Antares nuclear reactors. You will develop hardware from early layouts through detailed CAD, manufacturing, assembly, and testing.

What you will do

• Own the mechanical design and detailed definition of turbomachinery components and assemblies.
• Develop 3D CAD models, assemblies, and production drawings for rotating and stationary turbomachinery hardware.
• Support architecture and packaging trades through rapid iteration of 2D and 3D layouts.
• Evaluate materials, manufacturing processes, interfaces, assembly methods, and design concepts.
• Work with aerodynamic, structural, rotordynamics, thermal, manufacturing, and test engineers.
• Work directly with suppliers and internal manufacturing teams to resolve producibility, inspection, assembly, and nonconformance issues.
• Improve existing designs to reduce cost, lead time, part count, and manufacturing complexity.
• Incorporate lessons from manufacturing, assembly, and test into design updates.
• Support the design of test hardware, tooling, fixtures, and development rigs.
• Contribute to turbomachinery design practices and standards.

Required qualifications

• Bachelor’s degree in Mechanical, Aerospace, or a related engineering discipline.
• 3+ years of professional experience designing complex mechanical hardware and assemblies.
• Strong proficiency in 3D CAD and engineering drawing creation.
• Strong working knowledge of GD&T and ASME Y14.5.
• Ability to perform first-principles engineering calculations to support mechanical design decisions.
• Experience working directly with manufacturing engineers, machinists, suppliers, or inspectors to resolve hardware issues.
• Demonstrated ability to communicate technical information clearly.
• Flexibility to support hardware development milestones, including occasional weekend or long-hour pushes.

Nice to have

• Master’s degree in Mechanical, Aerospace, or a related engineering discipline.
• Experience designing turbomachinery for gas turbines, turbochargers, rocket engine turbopumps, or similar high-performance applications.
• Expert proficiency with NX for 3D CAD design and drafting.
• Experience performing tolerance stack-up analysis and defining fits, clearances, and assembly interfaces for precision rotating machinery.
• Proficiency with ANSYS Mechanical.
• Knowledge of manufacturing processes including turning, milling, drilling, grinding, EDM, brazing, welding, casting, and additive manufacturing.
• Experience supporting suppliers through manufacturing development and production.
• Strong organizational and communication skills.
