The Radar Mechanical Design Department leads mechanical design, development, and integration of some of the most innovative land-based and shipboard radars in the world. This includes phased array radar systems, electronic modules, pedestals, and power and cooling systems. The department comprises individuals with technical expertise and experience in hardware design, integration, and production support. In this position, you will be responsible for developing technical solutions for a wide range of mechanism and machine design challenges, such as mechanical design of motion control actuation systems & subsystems, including custom actuator and geartrain design, kinematic and dynamic analysis of mechanisms, design of machine elements, bearing design, selection and analysis. Responsibility extends across the entire life cycle of the product, from conceptualizing and design, to prototyping and manufacturing, integration and verification testing, through production support. You will be expected to apply sound first principles understanding to solve complex system problems while teaming with a cross-discipline team including electrical engineering, systems engineering, RADAR systems engineering, flight science, manufacturing engineering, supply chain and others.
