Principal mechanical engineer vs senior mechanical engineer

Differences between principal mechanical engineer and senior mechanical engineer duties and responsibilities

Principal mechanical engineer example responsibilities.

• Used SolidWorks to design implantable leads, anchors, introductory devices and other accessories.
• Manage and drive continuous improvement programs (CIP) of RF plasma ion immersion implanting equipment for the semiconductor industry.
• Provide mechanical design and sustaining engineering expertise to troubleshoot manufacturing defect trends and achieve a more robust and producible product.
• Used Matlab to compare results and gather data.
• Perform stress analysis and strength calculations using FEA and 1st principals.
• Used actual measurements to validate FEA model of complete fuel cell system.

Senior mechanical engineer example responsibilities.

• Create DFMEA documents to help manage risks and improve initial quality.
• Set up and manage PCB manufacturing including all chemical baths, lasers, and exposure equipment.
• Restructure VHDL code and chip/module hierarchy to achieve timing goals for the dual cache controller and the chip.
• Achieve timely convergence of complex designs by building RTL models from validation area and integrating them, before official model release.
• Lead FPGA development of key digital communication component used in successful demonstration of spacecraft radio link.
• Provide mechanical design and sustaining engineering expertise to troubleshoot manufacturing defect trends and achieve a more robust and producible product.
