Navigation Solutions products are engineered to provide resilient PNT performance for the warfighter operating in denied or degraded environments. This role directly ensures that GPS receivers and simulators maintain mission effectiveness when exposed to adversarial threats and operational challenges.
Essential Functions
Integrate, configure, and validate software defined radio (SDR) architectures used across all GPS simulators, ensuring accurate signal generation, modulation, and timing performance.
Develop and execute RF test methodologies tailored to SDR-based systems, including waveform verification, calibration procedures, and over-the-air (OTA) characterization.
Implement and maintain FPGA- and DSP based signal processing chains that support GPS, GNSS, and custom PNT waveforms within SDR platforms.
Troubleshoot SDR hardware/software interactions, including RF front-end behavior, digital interface control, and embedded firmware issues affecting simulator performance.
Create automated test scripts and diagnostic tools to evaluate SDR output fidelity, dynamic range, phase noise, and interference resilience.
Collaborate with system architects and RF engineers to define SDR integration requirements for next generation GPS simulators and PNT solutions.
Support STE development for SDR-based systems, ensuring compatibility with high-speed digital interfaces, RF switching networks, and precision timing sources.
Perform detailed data analysis on SDR-generated signals to confirm compliance with system specifications, military GPS standards, and program requirements.
Participate in acceptance testing and configuration management of SDR firmware loads, FPGA bitstreams, and associated calibration files.
Qualifications
Bachelor's Degree in Science, Technology, Engineering, or Mathematics (STEM) or related discipline with minimum 4 years prior relevant experience, 2-year post-secondary/AA Degree and 8 years prior experience, or Graduate Degree with 2 years of prior related experience, or in lieu of a degree, minimum of 8 years of prior related experience.
2+ years’ hands on experience working with software defined radios (SDRs), including configuration, waveform development, RF front end integration, and digital signal processing (DSP) workflows.
Active US Secret security clearance.
Preferred Additional Skills
Proficiency in SDR frameworks or toolchains (such as GNU Radio, MATLAB/Simulink, Ettus/USRP platforms, or equivalent internal architectures).
Strong understanding of RF fundamentals, including modulation schemes, filtering, signal generation, phase noise, dynamic range, and interference analysis.
Experience with Python for automation, scripting, signal validation, and test control.
Familiarity with FPGA or embedded‑processor‑based signal processing as used in SDR platforms, including interpreting firmware loads, bitstreams, and interface configurations.
Demonstrated ability to isolate and debug issues across RF hardware, digital signal chains, and embedded software layers.
Capable of working effectively both independently and in collaborative cross‑functional engineering environments.
Strong verbal, written, and presentation communication skills.
Flexible work schedule but 4/10 is preferred.
In compliance with pay transparency requirements, the salary range for this role in is $92,500 - $171,500. This is not a guarantee of compensation or salary, as final offer amount may vary based on factors including but not limited to experience and geographic location. L3Harris also offers a variety of benefits, including health and disability insurance, 401(k) match, flexible spending accounts, EAP, education assistance, parental leave, paid time off, and company-paid holidays. The specific programs and options available to an employee may vary depending on date of hire, schedule type, and the applicability of collective bargaining agreements.
