Job Summary
We are seeking a Senior MCU/RTOS Engineer to lead the development of our core execution environment. This role is responsible for the Internal Plumbing of our security processorensuring the RTOS is fast stable and hardened against common embedded vulnerabilities. You will work at the intersection of hardware and firmware ensuring that our silicons security features are fully leveraged by the software stack.
Key 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.
