We are seeking a Principal Engineer to own and drive the design of high-performance ball screw systems used in demanding aerospace, defense, medical, and industrial applications. This is a visible, technical leadership role where your decisions directly impact product performance, reliability, and innovation.
What You'll Own
- End-to-end design of precision ball screw assemblies (shafts, nuts, recirculation systems)
- Core architecture decisions: geometry, preload, life, and lubrication strategies
- Advanced analysis across contact stress, fatigue life, friction, stiffness, and thermal behavior
- FEA/CAE leadership for nonlinear contact, dynamics, and optimization
- Failure analysis and reliability improvement (FMEA, root cause)
- Material selection, heat treatment, coatings, and surface finish standards
- Test strategy including endurance, torque, and environmental validation
- Technical leadership across programs, while mentoring engineers and guiding design direction
- Collaboration with manufacturing and customers to solve complex challenges
Requirements:
- 10+ years in mechanical design, including deep experience with ball screws or precision motion systems
- Strong foundation in contact mechanics, tribology, and fatigue analysis
- Hands-on experience with CAD/CAE tools (SolidWorks, ANSYS, Abaqus, etc.)
- Experience with electromechanical actuators or aerospace systems
- Background in precision manufacturing or process development
- Familiarity with aerospace standards (DO-160, MIL-STD)
