FPGA SW Engineer Radar Systems

Overview

SAPPER INTELLIGENCE is building a remote sensing revolution! Our AI powered sensors bring exploration and reconnaissance to a new dimension. We develop solutions that overcome human limitations of sensing and recognition. Our systems enable the detection and inspection through soil and other materials. We will see through everything! With government customers and strong funding - we will give you all you need for excellence.

Your Job:

We are looking for Software Engineering Talents with hands-on experience and passion in building and integrating RF Software solutions in communication, telemetry, or radar systems. You will own the software stack that drives our RF systems — which may include host-side SDR control or FPGA and microcontroller programming. This role combines system-level software engineering with low-level firmware/FPGA development to ensure maximum flexibility and performance in radar operations.

You will be part of a small, early and focused team working closely with the company founders.

• Your actions will directly shape and impact the technical advancements.
• You will design and test software for advanced radar systems, including airborne (e.g., drone-based) configurations.

• Collaborate with RF and hardware engineers for system design.
• Work with SDRs and use of existing SDKs to implement and control RF functions.
• Develop robust control software for SDRs, frequency synthesizers, RF switches, gain stages, data acquisition, etc.
• Design and implement digital signal processing techniques (on FPGA or DSP) for sampling, filtering, calibration, synchronization, channel equalization, etc., prior to imaging pipelines.
• Build algorithms for frequency hopping, chirp scheduling, fast-tuning, and multi-channel timing alignment.
• Build automated testing setups for system validation.
• Communicate in real-time with other computer systems (Nvidia Jetson, NUCs, etc.), and optimize data streaming and buffering.
• Work closely with SAR engineers to provide clean, calibrated baseband data streams.

• Very good experience with FPGA development (Verilog or VHDL) for real time data acquisition, and signal processing systems.
• Very good experience with embedded systems and microcontroller programming (C, C++, or Rust) for board-level RF control via SPI/I²C/UART
• Strong programming background in C++ and Python for host-side SDR/RF control
• Good experience with digital signal processing.
• Previous experience with RF transceivers or Radar systems.
• Nice to have:
  Previous experience with FMCW or pseudo random signals.
• Nice to have:
  Previous experience with controlling and programming SDRs (e.g., USRP, Aaronia, Keysight, Ettus, LimeSDR).
