Job Details

This position is within the RF/Comm Systems group within the RF Payloads Center of Excellence, and the first assignment would be as technical lead for capacity modeling:
-Responsible for technical analysis of system capacity and throughput.
-Responsible for the modeling tools that will be used through the program life cycle for requirements development and system trades during the current phase, and later to merge with network modeling, provide channel simulations during test, serve as a mission planning tool during operations, and system trades for future evolution of the system.
-Current tool accepts platform trajectory and attitude time histories, static link budget parameters, waveform data, regulatory power constraints, weather availability, etc. and calculates time varying carrier to noise density and rates to each user locations. The lead will prioritize and lead development of features and execution of trades necessary to establish subsystem requirements and demonstrate performance that satisfies the business case.
-Analyses include beam to beam handover needs, sensitivity to platform motion and attitude control, optimization of beam laydown, determination of statistical rates across coverage area vs weather availability and platform design, throughput vs specific user load models, etc

Basic Qualifications
-Familiarity with Matlab programming concepts and data visualization.
-Familiarity with mathematical representation of dynamic geometric situations using vectors and transformations between multiple reference frames
-Familiarity with link budgets and associated concepts: EIRP/RIP/PFD, propagation losses vs weather availability, basic trades on aperture vs far-field gain patterns, etc
-Sufficient technical breadth to synthesize system level technical information, particularly as constraints or parameters for trades in modeling. Ability to incorporate multi-disciplinary information into modeling trades, like configuration constraints, mass and power budgets, cost constraints
-Ability and/or experience in providing technical leadership of a small team

Desired skills
-GUI, and graphic object manipulation a plus
-Experience with technical presentations and ability to write technical papers
