Job Description

RF/Microwave Design Engineer

Contract Assignment 3 Years, 40 hours weekly

Active Secret, US Citizen

Designs, develops, tests radio frequency (RF) and/or microwave systems architecture, components, circuits, or products. Includes antenna design, both reflector and array systems, frequency synthesizers, transmitters and receivers. Participates in electrical design tasks including requirements analysis, specification generation, interface definition, component selection, circuit simulation, schematic capture, and board layout. Participates in simulation, testing and troubleshooting of RF circuits and subsystems. Develops test plans and procedures for RF subsystems. Sub-system circuit design. Participates in required design reviews. Designs or develops radio frequency equipment and products which are used for the testing process of radio frequencies. Oversees and directs the production of the radio frequency devices and components which is to ensure that the design specifications are completely followed. Troubleshoots any problems found in radio frequency testing equipment or circuits. Knowledgeable in system architecture and specifications. Optimizes and analyzes the network and improving its performance if necessary. Ensures that reliability requirements are met in the design: these include E.M.C (electromagnetic compatibility), safety, manufacturability and thermal design aspects.

Advanced Sensor Systems and Test Beds Group (Group 33) supports Department of Defense (DoD) designing and developing various testbed systems and components to assist data collection for ballistic missile defense tests. Major activities within the group include system concept development for RF and optical systems, modeling and simulation, signal processing algorithm design, RF and optical system design and development, experimental field-testing and data analysis and development of one-of-a-kind operational and experimental test assets. The group has expertise in adaptive sensor array processing for both radar and communications, advanced real-time software techniques, signal detection and estimation, communications, and systems analysis. An Engineer level 1 contract staff are needed for rapid design and development of digital hardware and firmware controlling a number of RADAR systems developed by Client.
