Job Description:

This position focuses on Embedded Software Engineering for high-performance RF and DSP systems, leveraging Xilinx SoCs and FPGA-based signal processing chains in support of digital signal processing (DSP) programs.

What You'll Be Doing:

• Develop and maintain embedded Linux applications using PetaLinux on Xilinx SoC platforms to control and interface with FPGA-based DSP pipelines.
• Interface embedded software with FPGA logic using AXI, DMA, interrupts, EMIO, and memory-mapped peripherals to move high-rate RF I/Q data through DSP chains.
• Develop and test designs that incorporate high-speed RF ADC and DAC devices for wideband signal capture, generation, and processing.
• Configure, interface, and control ADC/DAC JESD204 (A/B/C) links and related JESD parameters to support reliable, high-throughput signal acquisition for DSP applications.
• Implement and debug SPI, I²C, GPIO, and register-level control interfaces for RF front-end components, clocking, and DSP-related control paths.
• Support JESD204 link bring-up and debug in coordination with FPGA and hardware teams, ensuring end-to-end DSP data-path integrity and timing closure.
• Perform system bring-up, debugging, calibration, and performance optimization with a focus on DSP metrics such as SNR, SFDR, EVM, and dynamic range.
• Collaborate closely with RF, FPGA, hardware, and systems engineers to define architectures, requirements, and interfaces for DSP-centric systems (e.g., SDRs, channelizers, and custom RF processing nodes).
• Validate designs using RF lab equipment (spectrum analyzers, signal generators, oscilloscopes, VNAs) and correlate measurements with expected DSP performance.
• Document software, DSP algorithms, system interfaces, and test procedures for repeatable deployment and verification.
• Write low-level firmware for board-level controls via FPGA and/or microcontroller in VHDL and/or C/C++, with an emphasis on supporting DSP data paths and timing.

What Required Skills You'll Bring:

• Ability to obtain a security clearance.
• US citizenship is required.
• BS or similar in an engineering discipline (Electrical Engineering, Computer Engineering, Computer Science, or related).
• 4 to 8 years of embedded software experience.
• Experience with RF transceivers (e.g., Analog Devices AD936x, AD908x, or similar) in DSP or SDR contexts.
• Understanding of digital electronics and ability to follow schematic diagrams, especially around high-speed data converters and FPGA interfaces.
• Familiarity with AXI interconnects, DMA engines, and high-throughput data paths for streaming DSP data.
• Knowledge of GNU toolchains, cross-compilation, and Yocto-based workflows for building embedded Linux images and applications.
• Understanding of wireless or SDR systems and how baseband DSP (e.g., modulation, filtering, channelization) maps onto RF hardware.

What Desired Skills You'll Bring:

• Design, implement, and optimize DSP algorithms for RF applications such as modulation/demodulation, filtering, FFTs, channelization, and digital down/up conversion, targeting Xilinx SoCs/FPGA-based systems.
• Experience writing Interface Control Documents (ICDs) or high-level design documents that define DSP data paths, timing, and control interfaces.
• Experience writing automated test code and controlling external RF test equipment (e.g., for automated DSP performance and regression testing).
• Ability to use test equipment such as oscilloscopes and logic analyzers in the debug of device control interfaces and DSP data paths.
• Experience with custom Linux drivers for high-speed data capture, streaming, and control in DSP-centric systems.

Security Clearance Requirement:

None
