Principal Embedded Firmware Engineer (Aerospace)

TL;DR

Principal Embedded Firmware Engineer (Aerospace): Architecting and developing low-level firmware for high-performance mixed-signal and digital SoCs with an accent on first-silicon success and hardware-software bridging. Focus on designing boot flows, driving post-silicon bring-up, and implementing robust system services for high-power satellite platforms.

Location: Remote (United States). Must be a U.S. Person as defined by ITAR (citizen, lawful permanent resident, or protected individual).

Salary: $190,000 - $285,000 + equity

Company

hirify.global is a Series C startup building the largest and highest-power satellites ever flown to unlock performance across every orbit.

What you will do

• Define overall embedded firmware architecture for custom SoCs, including boot flows, HALs, and system services.
• Develop low-level firmware in C/C++ and assembly for CPUs, DSPs, and microcontrollers.
• Lead pre-silicon development and post-silicon bring-up, including power-on sequencing and peripheral validation.
• Collaborate with SoC architects to define register maps, memory maps, interrupts, and debug infrastructure.
• Integrate RTOS or bare-metal environments with robust error handling and recovery mechanisms.
• Support manufacturing tests, production firmware, and long-term scalability across SoC generations.

Requirements

• 10+ years of experience in embedded firmware development with significant SoC-level ownership.
• Deep expertise in C/C++ for embedded systems and low-level hardware interactions.
• Hands-on experience with SoC bring-up from first silicon.
• Strong understanding of CPU architectures (ARM, RISC-V) and memory systems (SRAM, DRAM, DDR).
• Must be a U.S. Person (citizen or Green Card holder) to comply with ITAR export regulations.
• Experience with secure boot, hardware security modules, or cryptographic accelerators.

Nice to have

• Familiarity with pre-silicon environments such as RTL simulation, emulation, or FPGA prototyping.
• Experience with high-speed interfaces like PCIe, Ethernet, JESD, and SerDes.
• Background in radiation-tolerant, safety-critical, or high-reliability systems.

Culture & Benefits

• Unlimited paid time off.
• Comprehensive medical, dental, and vision coverage.
• Life insurance and paid parental leave.
• Equity ownership in the company.
• Opportunity to contribute to a groundbreaking space startup developing Kardashev Type II civilization infrastructure.
