Job Summary

The Principle Mechanical Design Engineer is responsible for the mechanical design, integration, and related testing for power electronics solutions for Aerospace and Defense customers.  The successful candidate must be capable of creating innovative solutions for exciting new programs with demanding packaging and environmental requirements while achieving a manufacturable solution.  Having knowledge of Aerospace and Defense standards, such as ARINC, RTCA DO-160 and MIL-STD-810, applying principles and best design practices to solutions is required.

The ability to communicate with customers as the Company's mechanical engineering expert regarding specifications for new products, as well as internally with the Company's design and manufacturing teams to support all mechanical design related activities is required.  The ability to apply knowledge and experience to mature the Company's mechanical design and testings processes while mentoring more junior mechanical engineers will be an integral part of the position.

Position specific tasks include, but are not limited, to the following:

• Create Line Replaceable Unit (LRU) mechanical packaging designs that are either industry standard (i.e., ARINC 400 or ARINC 600 compliant) or custom to best meet customer specifications.  This includes design layout, details design, tolerance studies, selection of material/parts and finishes, fastening and joining while considering manufacturability, shock, vibration, thermal stress, heat transfer, electromagnetic interference and magnetic shielding, reliability, maintainability, and sustainability.
• Lead mechanical improvement activities for LRU mechanical packaging designs throughout product life-cycle.  this includes capturing and maintaining TTEs mechanical engineering best practices, training and mentoring junior and senior mechanical engineers, facilitating mechanical engineering based Root-Cause Corrective Analysis (RCCA) activities, and supporting continuous improvement initiatives.
• Analyze thermal path and power consumption requirements to optimize mechanical design layouts.
• Perform detailed mechanical analysis to stimulate the effects of shock, vibration, thermal stress, heat transfer, and creepage clearance.
• Support prototype and qualification unit build activities.
• Support prototype, Highly-Accelerated Life Testing (HALT), and qualification unit environmental testing activities.
• Support and participate in related program meetings and engineering reviews.
• Lead and present mechanical design and analysis results in customer meetings, as required.
• Author engineering reports and assist in the preparation of world-class technical proposals.
• Support and participate in CCB activities, as required.
• Support supplier and material selection activities.
• Prepare engineering change orders, as required.
• Other duties, as assigned.

Essential Functions:

• Mechanical design, packaging and documentation of power electronics solutions (i.e., Power Supplies and Power Converters).
• Perform analyses to ensure that power electronics meet challenging performance and environmental conditions such as thermal, corona, vibration, and shock.
• Knowledge of fabrication such as machining, welding, sheet metal, etc.
• Design knowledge and experience with large magnetic and transformer products.
• Design knowledge of cooling methods which include liquid cooled, air-cooled, water-cooled, fuel cooled, etc.
• Design experience with packaging and mechanical designs in challenging environments such as corona, structural noise, airborne noise, shock audible noise, etc.
• Great communication skills including both verbal and written.
• Objective oriented team player, able to collaborate with a diverse team to achieve a specific task or objective as committed to stakeholders.

• 8+ years Mechanical Design Experience with Aerospace or Defense products.  
• Bachelor of Mechanical Engineering; Graduate degree in Mechanical Engineering preferred.
• Must be proficient in Solid Works, AutoCAD, or similar, MS Office.
• Previous experience working with both Aerospace and Defense Industry standards.
• This position requires use of information which is subject to the International Traffic in Arms Regulations (ITAR). All applicants must be U.S. persons within the meaning of ITAR.
