About the Department/College

The Radiant Center for Remote Sensing, in partnership with the Planetary Instrumentation eXperimentation and Exploration Laboratory (PIXEL) at Northern Arizona University, seeks a Postdoctoral Scholar to support the design, implementation, and field validation of embedded electronics for real-time sensor fusion aboard uncrewed aerial vehicles (UAVs). The position centers on custom hardware development, including schematic capture and multilayer PCB layout; VHDL/FPGA development for real-time data acquisition, timing, and on-board processing; and embedded software for sensor interfacing, synchronization, and system control.

This is one of several concurrent postdoctoral scholar recruitments at Radiant Center, and the successful candidate will collaborate closely with fellow postdoctoral researchers and faculty working simultaneously on related projects.

About the Position

The postdoctoral scholar will work alongside a full-time electrical engineer to integrate these systems onto UAV platforms, contribute to flight testing across the varied terrain around Flagstaff, and work collaboratively with interdisciplinary teams in engineering and the remote sensing sciences to translate results into technical reports, peer-reviewed publications, and deployable instrumentation. The postdoctoral scholar will also help mentor graduate and undergraduate student researchers supporting the project. This is an in-person, laboratory- and field-based position based in Flagstaff, AZ.

This position is primarily an office and laboratory-based design role. Most of the work is performed at a desk and on the bench: schematic capture and PCB layout, FPGA and firmware development, simulation, and hardware bring-up and debugging. Laboratory work involves electronics assembly and test equipment, oscilloscopes and logic analyzers, soldering and rework stations, 3D printers, and drone hardware, with routine exposure to small hand tools, soldering fumes, and low-voltage electrical hazards. Fieldwork is a smaller component, consisting of periodic UAV flight testing at sites in and around Flagstaff, occasionally in rugged terrain and variable weather, with infrequent overnight or multi-day travel for more distant field campaigns and for conference travel. The position may require occasional overtime, particularly around test campaigns and sponsor reporting deadlines.

Notice of Availability of the Annual Fire and Security Report

Each year Northern Arizona University releases an Annual Security Report. The report is a result of a federal law known as the Clery Act. The report includes Clery reportable crime statistics for the three most recent completed calendar years and discloses procedures, practices and programs NAU uses to keep students and employees safe including how to report crimes or other emergencies occurring on campus. In addition, the Fire Safety Report is combined with the Annual Security Report for the NAU Flagstaff Mountain Campus as this campus has on-campus student housing. This report discloses fire safety policies and procedures related to on-campus student housing and statistics for fires that occurred in those facilities. If you would like a free paper copy of the report, please contact the NAUPD Records Department at (928) 523-8884 or by visiting the department at 525 E. Pine Knoll Drive in Flagstaff.
