What is a gnu?

Gnu, also known as wildebeest, are large antelopes native to Africa. They are known for their distinctive appearance, with robust bodies, shaggy manes, and curved horns. Gnu are famous for their annual migration across the Serengeti and Maasai Mara, which is one of the largest and most spectacular animal migrations in the world. They play an important role in their ecosystem, serving as prey for large predators and helping to maintain grassland habitats.

How does a gnu software developer typically collaborate with open-source communities on large projects?

As a Gnu Software Developer, you'll often work alongside a diverse, global community of contributors. Collaboration typically takes place through mailing lists, version control platforms like Git, and online forums, where you’ll discuss bugs, propose features, and review code. Effective communication and a willingness to receive and give constructive feedback are key, since many projects are community-driven and rely on consensus. Participating in these communities also provides valuable networking, mentorship, and learning opportunities, which can significantly enhance your career growth.

What is the difference between Gnu vs Linux Developer?

AspectGnuLinux Developer
CredentialsTypically requires knowledge of GNU tools, scripting, and open-source licensesRequires programming skills, Linux system knowledge, and often certifications like LPIC or RHCE
Work EnvironmentWorks mainly on GNU tools, software development, and open-source projectsDevelops or maintains Linux-based systems, kernels, or applications
Industry UsageUsed in open-source software development, Linux distributions, and GNU projectsEmployed in system administration, software development, and Linux system engineering

The main difference is that Gnu refers to the collection of free software tools and projects, while a Linux Developer focuses on creating or maintaining Linux-based systems and applications. Both roles require programming skills and familiarity with open-source principles, but their focus areas differ within the open-source ecosystem.

Job description

Position Title: Senior Principal Field Programmable Gate Array & Digital Signal Processing Engineer

Location: Hybrid, in office in Alexandria, VA

Clearance Requirement: TS/SCI

Employment Type: Full Time

Research Innovations, Inc. (RII) is breaking through the big, slow status quo with transformative technology that fundamentally improves the world. We build advanced software solutions for government and military missions, applying agile development and user-centered design to solve complex, mission-critical problems.

Dragonfly is redefining tactical SIGINT and Electronic Warfare by combining advanced RF sensing, GPU-accelerated processing, artificial intelligence, and high-performance FPGA architectures into a portable, mission-ready platform. As the Principal FPGA & DSP Engineer, you will serve as the technical leader responsible for designing and delivering the next generation of real-time FPGA-based signal processing capabilities that enable rapid spectrum awareness, signal exploitation, and electronic warfare operations. Working closely with hardware, software, AI, and RF engineering teams, you will architect high-performance firmware solutions that transform advanced algorithms into deployable capabilities supporting the Department of Defense, Intelligence Community, and allied mission partners.

WHAT YOU WILL BE DOING

  • Lead the FPGA firmware architecture for Dragonfly, defining the optimal partitioning of signal processing across FPGA, GPU, and CPU to meet mission latency, throughput, and SWaP requirements.

  • Migrate GPU-based digital signal processing algorithms into efficient FPGA implementations, including floating-to-fixed point conversion, quantization analysis, word-length optimization, and bit-accurate verification.

  • Design reusable, portable FPGA IP that supports multiple AMD/Xilinx platforms including RFSoC, Versal, UltraScale+, and Zynq.

  • Develop real-time FPGA implementations for advanced RF signal processing including digital down conversion, filtering, FFTs, channelization, synchronization, demodulation, and protocol exploitation.

  • Implement and optimize wireless protocol processing for technologies such as Wi-Fi, Bluetooth/BLE, LoRa, LTE, and 5G NR.

  • Develop FPGA capabilities supporting direction finding (DF), beamforming, geolocation, and multi-channel phase-coherent signal processing.

  • Establish FPGA verification methodologies including simulation, automated regression testing, timing closure, hardware validation, and over-the-air testing.

  • Support hardware bring-up, integration, production validation, and field testing of Dragonfly systems.

  • Serve as the technical authority for FPGA firmware and DSP architecture, conducting design reviews, mentoring engineers, and establishing engineering best practices.

  • Contribute to product roadmap development, customer engagements, technical proposals, IRAD efforts, and emerging EW/SIGINT capability development.

WHAT YOU HAVE DONE

  • Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or related field; Master's or PhD preferred.

  • 10+ years of FPGA development experience supporting RF, SDR, SIGINT, radar, wireless communications, or Electronic Warfare systems.

  • Demonstrated ownership of FPGA architecture from concept through deployed production systems.

  • Active Secret clearance required; ability to obtain or maintain TS/SCI preferred.

  • Expert proficiency with VHDL and/or SystemVerilog, RTL design, pipelining, finite state machines, clock domain crossing, and timing closure.

  • Extensive experience with AMD/Xilinx development tools including Vivado, Vitis, Vitis HLS, and RFSoC or Versal platforms.

  • Strong background in digital signal processing including FFTs, digital down/up conversion, FIR/IIR/CIC filters, multirate processing, fixed-point design, CORDIC, and AGC.

  • Experience implementing high-speed interfaces including AXI, PCIe, Ethernet, DDR memory, Aurora, and JESD204B/C.

  • Proficiency with MATLAB and/or Python for algorithm development and hardware verification, along with C/C++ development in Linux environments.

  • Experience with FPGA simulation, debugging, board bring-up, and RF laboratory validation using industry-standard tools.

  • Familiarity with Git, Agile development methodologies, and cross-functional hardware/software engineering teams.

EVEN BETTER

  • Experience developing CUDA or GPU-based DSP algorithms and migrating them to FPGA implementations.

  • Experience implementing beamforming, direction finding, geolocation, MUSIC/ESPRIT, TDOA, or FDOA algorithms.

  • Knowledge of LTE, 5G NR, Wi-Fi, Bluetooth/BLE, LoRa, or other modern communications waveforms.

  • Experience with High-Level Synthesis (HLS), Simulink, MATLAB HDL Coder, or Model Composer.

  • Familiarity with RFNoC, GNU Radio, OpenCPI, SOSA, or CMOSS architectures.
