About the Job

This position requires expertise in RF antenna design and simulation tools, as well as a solid understanding of board-level schematic design and PCB circuit layout. If you have strong problem-solving skills, attention to detail, and a passion for innovation, this opportunity is for you! Your contributions will be essential in advancing our RF antenna projects for the EW team.

What you'll do:

• Collaborate with a multidisciplinary team of software and hardware engineers to develop software defined radios; including the implementation of DSP techniques into software and firmware and integration activities
• Guide DSP engineers in the execution of DSP trade studies and optimization of signal processing and machine learning algorithms for deployment on FPGAs and GPUs.
• Board bring up, test, and circuit optimizations.
• Prototype and integrate new SDR platforms that can operate across current defense and commercial waveforms, from legacy tactical radios to next-generation cellular and mesh protocols.
• Develop, port, and optimize waveforms and DSP pipelines for high-performance, real-time execution across SDR frameworks, FPGAs, and embedded platforms.
• Automate tests to enhance test coverage and ensure reproducibility and repeatability.
• Own lab-based integration and testing of RF subsystems, driving iteration cycles that improve product reliability, performance, and deployment readiness.
• Leverage data analysis and existing tools to reproduce and characterize failures.
• Support and perform field testing and act as a liaison to conduct ground and flight testing.
• Collaborate across multi-disclipinary teams (software, hardware, RF, networking) to ensure successful end-to-end system integration.
• Support product deployments through lab replication of field scenarios, troubleshooting, and post-mission analysis.
• Develop and maintain test standards, design and develop test equipment, or procuring and handling purchased test capital equipment to support test readiness.
• Facilitate electrical system performance, calibration, durability, and environmental testing of developmental components and systems per test plan.
• Integration testing of subassemblies and systems including RF and digital hardware, firmware, embedded software, and application software.
• Advance the state of the art by contributing to internal tools, frameworks, and methodologies that make SDR development faster and more reliable.
• Analyze and drive coverage and analysis of failures observed in integration, characterization, and system level testing.
• Characterize wireless communication systems and devices.

Required qualifications:

• Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or related fields
• 5+ years relevant RF design experience.
• 8+ years of experience in waveform development, DSP or SDR engineering
• Experience with RF cascade analyses, component selection, and component evaluations.
• Skilled with modeling, simulation, analysis, design, test and optimization of RF power amplifiers and supporting circuits like couplers, detectors, and bias sequencing / control.
• Demonstrated experience with defense waveforms (e.g. WNW, TSM-X, LINK 16, Silvus, SINCGARS) and commercial standards (LTE, 5G NR, Wi-FI, SATCOM, etc).
• Hands-on experience with one or more SDR toolkits/frameworks: GNU Radio, REDHAWK, Ettus/USRP, Xilinx RFSoC, custom FPGA DSP pipelines.
• Ability to travel to and work at remote sites supporting test integration, commissioning, and training as required.
• Strong background in signal processing, modulation/demodulation, PHY/MAC integration and RF system performance optimization.
• Proficiency in C/C++ and Python; exposure to HDL (VHDL/Verilog) a plus.
• Comfortable in the lab with RF test equipment (spectrum analyzers, VNAs, signal generations, channel emulation) and able to iterate quickly on prototypes.
• Excellent written, verbal, interpersonal, communication, and organization skills.
• Ability to obtain and maintain a security clearance.
• Experience with schematic capture and guiding PCB layout.
• Experience with test plan development and test execution.

Desired qualifications:

• Knowledge of regulatory standards and compliance requirements in the aerospace industry.
• Experience with 3D electromagnetic modeling and simulation using tools like Ansys HFSS, CST, and Feko.
• Experience deploying SDR systems in operational defense environments
• Familiarity with mesh networking protocols, MANET radios, and multi-node RF environments.
• Knowledge of embedded Linux, real-time systems, and SDR driver stacks
• Proven ability to thrive in fast-paced, iterative engineering environments
• Familiar with wireless communication protocols and test methods.
• Familiar with military and spectrum regulatory standards and test methods.
• Experience with RF requirement development and feasibility analyses.
• Familiar with programming languages like Python for analysis and test automation.
• Experience with PCB design / layout.
