Principal Firmware Engineer – Digital ASIC

Job description

Job responsibilities

• Own and lead the architecture, design, implementation, integration, and validation of complex embedded firmware for custom digital ASICs, including Digital Beamforming (DBF) ASICs.
• Develop ROM code and runtime firmware for DBF ASICs, including beam pointing, analog calibration, FEIC management, SerDes link management, secure boot, telemetry, and sideband control.
• Define and own hardware/software interfaces, including register interfaces, control protocols, initialization sequences, interrupt handling, and hardware/software partitioning.
• Develop comprehensive firmware verification and validation strategies, including detailed test plans, functional testing, integration testing, regression testing, and performance characterization.
• Drive pre-silicon firmware development, integration, debugging, and verification using simulation, emulation, and FPGA prototyping platforms.
• Lead post-silicon firmware bring-up, debugging, characterization, and validation of custom ASICs, resolving complex hardware/software integration issues.
• Own end-to-end firmware delivery to silicon validation, system test, and manufacturing teams , including production test firmware, diagnostic capabilities, firmware release packages, and supporting documentation.
• Work closely with test and manufacturing engineering teams to define firmware requirements, develop production test and diagnostic capabilities, and support manufacturing readiness.

Job requirements

• Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related technical discipline.
• 10+ years of experience in embedded firmware development, low-level software, or hardware/software systems development.
• Extensive hands-on experience developing embedded firmware in C, including bare-metal and resource-constrained environments.
• Demonstrated experience architecting, developing, and delivering firmware for complex digital ASICs, SoCs, microcontrollers, or hardware accelerators.
• Strong understanding of embedded processor architectures, memory systems, interrupts, DMA, peripheral interfaces, and hardware register programming.
• Experience defining hardware/software interfaces and working closely with ASIC or FPGA design and verification teams.
• Proven experience developing firmware verification strategies, detailed test plans, and automated validation frameworks.
• Demonstrated experience with pre-silicon firmware integration, hardware/software debugging, and post-silicon bring-up.
