Senior DBF Firmware Engineer

Minimum Qualifications:

• Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related technical discipline.
• 10+ years of experience in firmware development.
• Experience developing software in C.
• Experience writing software that directly controls hardware, such as firmware, kernel device drivers, or low-level embedded code.
• Experience debugging and validating embedded firmware and hardware/software interactions.

Preferred Qualifications:

• Experience with RF and communications concepts such as OFDM, digital beamforming, phased antenna arrays, and 3GPP specifications.
• Experience leading and mentoring other engineers.
• Experience with RTOS and hard real-time constraints, such as FreeRTOS or Zephyr.
• Experience with Cortex-M ISA.
• Experience working with DSP accelerators.
• Experience with Rust, especially no-std Rust.
• Experience with CI flows and automated hardware-in-the-loop (HIL) testing.
• Understanding of board-level hardware design, including the ability to work with schematics and data sheets.
• Experience testing firmware using pre-silicon simulation and emulation platforms such as QEMU, Palladium, or ZeBu.
• Experience with bring-up of custom silicon.

Key Responsibilities:

• Develop ROM code and runtime firmware for Digital Beamforming (DBF) ASICs.
• Develop and support firmware for beam pointing, analog calibration, FEIC management, SerDes link management, secure boot, telemetry, and sideband control of DBF ASICs.
• Work with hardware and communications systems engineers to define and implement firmware and hardware interfaces.
• Support pre-silicon firmware development, integration, and validation.
• Support post-silicon bring-up, debugging, and validation of custom DBF ASICs.

• Candidates may be subject to verification and BGS screening as per applicable law.
