Senior Turbomachinery Design Engineer

About the Role:

As a Senior Turbomachinery Design Engineer, you will own the mechanical design of turbomachinery components and assemblies for Antares nuclear reactors. You will develop hardware from early layouts and architecture trades through detailed CAD, drawings, manufacturing, assembly, and testing. You will work closely with turbomachinery engineers, analysts, manufacturing engineers, and suppliers throughout development.

The ideal candidate has experience designing complex mechanical hardware and strong skills in CAD, engineering drawings, GD&T, materials, and manufacturing processes. You can make practical design tradeoffs that balance performance, reliability, manufacturability, cost, and schedule.

Roles & Responsibilities:

• 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 during early development.
• Work with aerodynamic, structural, rotordynamics, thermal, manufacturing, and test engineers to develop integrated designs.
• 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 for CAD, drawings, producibility, and reliability.

Basic Qualifications:

• Bachelor’s degree in Mechanical, Aerospace, or a related engineering discipline.
• 5+ 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.

Preferred Skills & Experience:

• 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.

Additional Requirements:

• Flexibility to support hardware development milestones, including occasional weekend or long-hour pushes.
