Principal Mechanical Engineer

Worker Type Regular Job  Description Summary The  Principal Mechanical Engineer applies engineering techniques to design, install, modify, analyze, repair and test tools, engines, machines and other mechanically functioning equipment. In this role, The Sr. Staff Mechanical Engineer leads in the mechanical design, testing, and production of electrical machines as well as the design of electronics packaging for high altitude aerospace applications.

One leads the mechanical packaging development effort for electronic equipment that withstand stringent environmental requirements (i.e., mass, volume, thermal, vibration). Manages mid-size development projects outsourced to sub-contractors (development of a system, equipment or components).Position Responsibilities Leads or supports the thermal, structural, dynamic, and fluid flow analysis efforts for electronics equipment

Leads the testing and data collection in the laboratory and the field

Models the mechanical devices and selects the proper material

Performs stress and fatigue analysis;
Performs thermal analysis and selects bonding material

Develops mechanical drawings and specifies the dimensional tolerances

Develops and implements assembly instructions and test procedures

Develops and implements test plans and test procedures to verify designs

Works on significant and unique issues where analysis of situations or data requires an evaluation of intangibles. Exercises independent judgment in methods, techniques and evaluation criteria for obtaining results

Acts independently to determine methods and procedures on new or special assignments. May supervise the activities of others.
