The RoleWe are seeking a Senior Embedded Firmware Engineer to develop and enhance low-level embedded firmware for high-performance mixed-signal and digital SoCs. In this role, you will contribute to the bring-up, validation, and production readiness of custom silicon by working closely with digital ASIC, mixed-signal, RF, verification, and system engineering teams. You will help implement core firmware components, validate hardware functionality, and ensure reliable, scalable firmware foundations for next-generation products.
Responsibilities- Contribute to the design and implementation of embedded firmware architecture, including boot flows, HAL components, drivers, and system services.
- Develop low-level firmware in C/C++ (and assembly when required) for CPUs, DSPs, and microcontrollers within custom SoCs.
- Implement and maintain bootloaders, secure boot flows, and early hardware initialization sequences.
- Develop device drivers for on-chip peripherals such as DMA engines, memory controllers, interconnects, SerDes, ADC/DAC interfaces, timers, and GPIO.
- Participate in pre-silicon firmware development and validation activities.
- Support post-silicon bring-up, including power-on sequencing, clock/reset initialization, memory bring-up, and peripheral testing.
- Debug hardware/firmware interactions using JTAG, logic analyzers, oscilloscopes, trace tools, and custom debug instrumentation.
- Collaborate with SoC architects and designers to refine register maps, memory maps, interrupt structures, DMA flows, and debug infrastructure.
- Provide firmware input during design reviews and silicon development milestones.
- Bring up and integrate RTOS or bare-metal environments.
- Support integration with higher-level system software or application processors.
- Implement robust error handling, logging, and recovery mechanisms.
- Contribute to manufacturing test firmware, production firmware, and field diagnostics.
- Help ensure long-term maintainability and scalability of firmware across multiple SoC generations.
Qualifications- 5+ years of experience in embedded firmware development for SoCs or complex embedded systems.
- Strong proficiency in C/C++ for embedded systems and a solid understanding of low-level hardware interactions.
- Hands-on experience with SoC bring-up or board-level bring-up.
- Strong understanding of CPU architectures (ARM, RISC-V, or similar), memory systems (SRAM, DRAM, DDR, caches), interrupts, DMA, and low-power states.
- Experience collaborating with ASIC/SoC design or hardware engineering teams.
- Demonstrated ability to debug complex hardware/firmware issues.
Nice to Have- Experience with secure boot, hardware security modules, or cryptographic accelerators.
- Familiarity with pre-silicon environments such as RTL simulation, emulation, or FPGA prototyping.
- Experience with high-speed interfaces (PCIe, Ethernet, JESD, SerDes).
- Background in satellite communication, networking, compute, automotive, or other high-reliability systems.
- Experience developing firmware for radiation-tolerant or mission-critical systems.
Compensation and Benefits:- Base salary range for this role is $160,000 - $220,000 + equity in the company
- Salary will be based on several factors including, but not limited to: knowledge and skills, education, and experience level
- Comprehensive benefits package including paid time off, medical/dental/vision/ coverage, life insurance, paid parental leave, and many other perks
If you don't meet 100% of the preferred skills and experience, we encourage you to still apply! Building a spacecraft unlike any other requires a team unlike any other and non-traditional career twists and turns are encouraged!
