JOB DUTIES AND RESPONSIBILITIES

Perform satellite interference, equivalent power flux-density (EPFD), power flux-density (PFD), and link budget analyses to assess spectrum-sharing compatibility and regulatory compliance, including non-geostationary satellite orbit (NGSO) systems. Prepare technical analyses, system parameters, and supporting documentation for ITU filings, FCC applications, international market-access requests, and earth-station licensing activities, including Schedule S and license modifications. Support satellite network coordination and regulatory proceedings by preparing interference studies, technical correspondence, and briefing materials while participating in external engagements under the Director's guidance. Assist with the design and development of communications system architectures, interfaces, subsystems, and performance models. Perform system modeling, link analysis, performance evaluation, trade studies, simulation, and system integration activities. Review system requirements, interface specifications, architecture documentation, analytical results, and technical documentation supporting system implementation. Perform verification, validation, testing, simulation, integration, and troubleshooting activities. Analyze simulation results, system performance data, test results, and engineering observations to identify trends and recommend solutions. Support root cause investigations, engineering changes, system improvements, defect resolution, and corrective actions. Collaborate with systems, software, RF, electrical, mechanical, integration and test, quality, and program teams throughout product development. Prepare technical documentation, interface control documentation, verification reports, engineering reports, and engineering change documentation. Participate in design reviews, technical investigations, customer support activities, system integration, and verification activities. Review communications systems engineering methods, modeling practices, requirements management processes, and development activities to identify improvement opportunities. Apply engineering standards, company procedures, customer requirements, and systems engineering best practices throughout the product lifecycle. Contribute to continuous improvement initiatives that strengthen system performance, requirements quality, modeling accuracy, and engineering effectiveness.
