Researches, plans, designs and develops mechanical products and systems such as instruments, controls, robots, engines, machines and mechanical, thermal hydraulic or heat transfer systems for production, transmission, measurement, and use of energy. Applies research to the planning, design, development, and testing of mechanical and/or electromechanical systems, instruments, controls, engines, and/or machines. This position supports the construction of Columbia Class modules in the JMAF and SJB where both early construction of the large structural hull sections are built in APCO fixtures, along with final assembly of the modules prior to shipment to EB. This position requires a solid understanding of structural fabrication standards in support of JMAF work, along with a strong mechanical background to support final assembly of the units in the SJB.
