Description
The RF Design Software Engineer will play a critical role in the design, development, and testing of Azure’s complex PCBs and PCBAs. This individual will work with the HW design engineering team in the design development and testing of complex RF and mixed signal circuit boards from prototype to full rate production.
RF Design Software Engineer – DSP, Xilinx & Embedded Linux
Key Responsibilities:
- Design, implement, and optimize DSP algorithms for RF applications such as modulation/demodulation, filtering, FFTs, channelization, and digital down/up conversion.
- Develop and maintain embedded Linux applications using PetaLinux on Xilinx SoC platforms.
- Interface embedded software with FPGA logic using AXI, DMA, interrupts, EMIO, and memory-mapped peripherals.
- Communicate with and control programmable RF devices, including:
- RF attenuators
- PLLs and frequency synthesizers
- Programmable gain amplifiers
- RF upconverters and downconverters
- High-speed RF ADC and DAC devices
- Interface and control of ADC/DAC JESD information for signal processing.
- Implement and debug SPI, I²C, GPIO, and register-level control interfaces.
- Support JESD204 (A/B/C) link bring-up in coordination with FPGA and hardware teams.
- Perform system bring-up, debugging, calibration, and performance optimization.
- Collaborate with RF, FPGA, hardware, and systems engineers on architecture and requirements.
- Validate designs using RF lab equipment (spectrum analyzers, signal generators, oscilloscopes, VNAs)
- Document software, algorithms, interfaces, and test procedures
- Write low level firmware for board level controls via FPGA and/or microcontroller in VHDL and/or C/C++.
Required Experience:
- Ability to obtain security clearance.
- 4-year degree in college in an engineering discipline.
- 10+ years of electronics design experience.
- Experience with RF transceivers (e.g., Analog Devices AD936x, AD908x, or similar)
- FPGA design experience using Vivado and/or Vitis
- Understanding of Digital Electronics and able to follow Schematic diagrams.
- Familiarity with AXI interconnects, DMA engines, and high-throughput data paths
- Experience with spidev, IIO frameworks, or custom Linux drivers
- Knowledge of GNU toolchains, cross-compilation, and Yocto-based workflows
- Understanding of wireless or SDR systems (LTE, 5G, Wi-Fi, radar, or custom waveforms)
Optional Experience:
- Experience working with Cadence tools including schematic design with OrCad.
- Experience writing Interface Control Documentation or high-level design documents.
