• 10+ years of progressive mechanical design experience, preferably in valve, actuator, or related industrial equipment environments.

• Advanced SolidWorks expertise, including complex part and assembly modeling.

• Strong knowledge of drafting practices and dimensioning standards based on ASME Y14.5.

• Proven ability to create and modify 3D parts using surfacing and advanced modeling techniques.

• Strong understanding of mechanical design principles, material compatibility, and product configuration control.

• Demonstrated ability to lead technical problem-solving efforts in a fast-paced engineering environment.

• Excellent verbal and written communication skills.

• Ability to collaborate effectively with a global team.

• Self-starter who can work independently with minimal supervision while influencing cross-functional teams.

Preferred:

• Masters or Doctorate Engineering degree.

• Experience with ANSYS tools, including CFD and FEA.

• Background in casting and other valve manufacturing methods.

• CSWP certification.

• Familiarity with applicable ASME, ANSI, and MSS standards.
