Staff MCU/RTOS Engineer

Responsibilities

• RTOS Architecture: Design and implement the real-time execution environment (e.g., FreeRTOS, Zephyr, or custom kernels) to handle multi-threaded security tasks.
• Security-Aware Driver Development: Develop low-level drivers (DMA, SPI, I2C, Mailbox) with a focus on input validation and memory isolation to prevent buffer overflows or unauthorized access.
• MPU Configuration: Design and maintain the Memory Protection Unit (MPU) configurations to enforce strict process isolation and prevent code execution in data regions.
• IPC Stability: Optimize the Inter-Processor Communication (IPC) between the MCU and the x86 Host/BMC, ensuring high throughput without compromising the security boundary.
• Firmware Hardening: Apply "Secure Coding" practices (such as MISRA-C) and participate in threat modeling to identify potential architectural weaknesses in the firmware.
• Experience: 8+ years in MCU-level C programming (ARM Cortex-M, RISC-V, or similar).
• RTOS Mastery: Deep understanding of context switching, interrupt handling, mutexes, and real-time scheduling.
• Security Concepts: Strong foundational knowledge of Secure Boot, Chain of Trust, and Memory Isolation (MPU/MMU).
• Debugging: Proficiency with JTAG/SWD, logic analyzers, and GDB for deep-system debugging.
• Hardware Interface: Practical experience with high-speed serial protocols and an understanding of how hardware-based crypto-accelerators interact with firmware.
• Preferred Skills:
• Experience with NIST SP 800-193 (PFR) and OCP security standards.
• Familiarity with side-channel attack mitigations and fault injection protection.
• Previous experience in a "Tiger Team" environment preparing for major industry events.
• Additional Information
• Axiado is committed to attracting, developing, and retaining the highest caliber talent in a diverse and multifaceted environment. We are headquartered in the heart of Silicon Valley, with access to the world's leading research, technology and talent.
