Evaluate, select, specify, design, modify, test, and / or integrate sensors, electronic modules (custom and COTS), cables, connectors, power subsystems.

Apply basic knowledge of HDL design using VHDL / Verilog to write, simulate, synthesize and test designs used within various logic devices (SoC,FPGA / CPLD).

Conduct experimental tests on equipment, evaluate results, followed by specification development for selecting components and equipment for deliverable systems.

Generate and maintain requirements documents, functional specification documents, interface control documents and engineering drawings while applying configuration management policies.

Develop project test plans and test procedures, provide test planning support, assist in the execution of both lab testing and field testing.

Provide field support planning, mobilization / de-mobilization support, and other field support in general.

Interact with outside customers, suppliers, and functional peer groups.

Provide status reports to project managers and / or project lead as required.

Some travel and work at remote sites for limited time periods will be required.
