Manufacturing Engineers learn production operations and the manufacturing discipline in a controlled environment. They develop manufacturing engineering skills, an understanding of manufacturing (cost, quality, safety and schedule), and Raytheon systems and tools. MEs build technical depth in manufacturing processes and are accountable for improvement and optimization.

Primary responsibilities include developing the comprehensive manufacturing process for 3D metal parts for various radar, integrated sensor, and effector programs. The candidate will define materials, develop work holding solutions, create multi-axis CNC machining programs, develop inspection plans, and create process instructions for operators to follow. This position requires close cooperation with the Operations team and other engineering disciplines. The desired candidate will possess excellent communication skills and be capable of working in a dynamic team environment.
