[Remote] Senior Firmware Engineer, ASIC

Note: The job is a remote job and is open to candidates in USA. K2 Space Corporation is building the largest and highest-power satellites ever flown, aiming to unlock unprecedented performance levels across various orbits. They are seeking a Senior Embedded Firmware Engineer to develop and enhance low-level embedded firmware for high-performance mixed-signal and digital SoCs, contributing to the bring-up, validation, and production readiness of custom silicon.

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

Skills

• 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
• 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

Benefits

• Equity in the company
• Comprehensive benefits package including paid time off, medical/dental/vision/ coverage, life insurance, paid parental leave, and many other perks
