Technologist III

JPL/NASA•Pasadena, CA

8d•$123,864 - $170,248•Onsite

About The Position

The JPL Communications and Instruments Division perform scientific investigations, advanced technology research, engineering developments and system implementations encompassing space telecommunications, tracking and active remote sensing using electromagnetic waves. The Flight Communications and Tracking Section (362) provides cost-effective space communications systems, software defined radios, high power RF amplifiers, and power supplies that support primary telecom subsystems and major radar and radiometer science payloads. The section also provides Global Navigation Satellite System (GNSS) flight equipment, radiometric science instruments, high stability frequency standards and clocks and seismometers for NASA/JPL missions. In addition to flight hardware expertise, the section specializes in collection of and processing of worldwide, fixed site, GNSS data that is processed into clock, atmospheric, and ionospheric GNSS correction metrics. The section also develops high stability frequency references and clocks for flight and ground applications. The Flight Communications & Tracking Section at JPL is looking for a Technologist III to join their Frequency and Timing Systems Group. The Group provides the Deep Space Network (DSN) with precision atomic frequency and time references and distribution systems and operates state-of-the-art microwave and optical metrology references and test capabilities in the Frequency Standards Test Laboratory. As a member of this Group, you will have an opportunity to be involved with a diverse engineering team working in the development and implementation of advanced state-of-the-art frequency and timing systems (FTS).
