Embedded Software Engineer

Responsibilities

• Develop and maintain embedded Linux applications using PetaLinux on Xilinx SoC platforms to interface with FPGA-based DSP pipelines.
• Interface embedded software with FPGA logic using AXI, DMA, interrupts, and memory-mapped peripherals to move high-rate RF I/Q data.
• Configure and control ADC/DAC JESD204 links to support high-throughput signal acquisition for DSP applications.
• Implement and debug SPI, I²C, GPIO, and register-level control interfaces for RF front-end components.
• Perform system bring-up, debugging, and performance optimization focusing on DSP metrics like SNR, SFDR, and EVM.
• Collaborate with RF, FPGA, and hardware engineers to define architectures for SDRs, channelizers, and custom RF processing nodes.
• Write low-level firmware for board-level controls via FPGA or microcontrollers in VHDL and/or C/C++.

Requirements

• US citizenship is required.
• Ability to obtain a security clearance.
• BS in Electrical Engineering, Computer Engineering, Computer Science, or a related engineering discipline.
• 4 to 8 years of embedded software experience.
• Experience with RF transceivers (e.g., Analog Devices AD936x, AD908x) in DSP or SDR contexts.
• Familiarity with AXI interconnects, DMA engines, and high-throughput data paths.
• Knowledge of GNU toolchains, cross-compilation, and Yocto-based workflows.
• Understanding of wireless or SDR systems and baseband DSP mapping onto RF hardware.

Preferred Qualifications

• Experience designing and optimizing DSP algorithms (FFTs, filtering, modulation) for Xilinx SoCs.
• Experience writing custom Linux drivers for high-speed data capture and streaming.
• Proficiency using RF lab equipment such as spectrum analyzers, signal generators, and VNAs.
• Experience writing automated test code for DSP performance and regression testing.
