Embedded Firmware Engineer (Sr Engineer/Staff)

We are seeking a highly motivated and hands-on Senior Embedded Firmware Engineer to contribute to the development, validation, and bring-up of a next-generation ultra-low-power Edge AI sensing platform. In this role you will work across always-on sensing, sensor fusion, and Edge AI workloads on embedded MCU, DSP, AI accelerator, and sensor hub subsystems - collaborating closely with ASIC, FPGA, hardware, AI, and product teams to implement and validate firmware from pre-silicon development through silicon bring-up and into production. The ideal candidate brings strong embedded firmware skills, hands-on experience with low-level debugging and hardware bring-up, and a genuine interest in working at the intersection of firmware, hardware, and edge AI., * Develop, own, and deliver firmware modules and features in C/C++ for ARM Cortex-M/A microcontrollers and SoC platforms used in MEMS sensor products.

• Participate in and take ownership of hardware bring-up tasks: power sequencing, peripheral initialization, clock configuration, and early validation of new sensor platforms.
• Follow and contribute to firmware coding standards and architecture guidelines; flag issues and suggest improvements during code reviews.
• Support firmware release and qualification activities: run regression test suites, document results, and help track issues through to resolution.
• Develop and maintain a reusable, well-tested driver framework for serial interfaces: UART, SPI, I²C, CAN, PDM, I3C, and USB.
• Implement and validate calibration, compensation, and self-test routines for sensor characterization and manufacturing test flows.
• Collaborate with hardware engineers at the schematic and PCB level; contribute to design-for-testability and design-for-manufacturing reviews.
• Work with systems and applications engineers to support integration of firmware into customer platforms and help troubleshoot field issues.

• Bachelor's degree (or higher) in Electrical Engineering, Computer Engineering, Electronics, or a closely related field.
• 5+ years of hands-on embedded firmware engineering experience, with a demonstrable track record of shipping products to mass production.
• Strong C and C++ programming skills for embedded systems; good understanding of software structure, modularity, and resource-constrained design.
• Solid working knowledge of an RTOS (FreeRTOS, Zephyr, or similar): task scheduling, inter-task communication, mutexes, and basic real-time debugging.
• Experience taking a firmware feature or driver from design through integration and testing, ideally on a shipped or near-shipped product.
• Strong knowledge of microcontroller architecture: DMA, interrupt controllers (NVIC), cache coherency, power management, and clock distribution.
• Thorough understanding of serial communication protocols: UART, SPI, I²C, CAN, PDM, and digital MEMS output interfaces.
• Thorough understanding of MEMS sensor families: IMU, pressure, microphone, or environmental sensors.
• Familiarity with code quality practices: static analysis tools (PC-lint, Coverity, or SonarQube), code coverage, and adherence to coding guidelines such as MISRA-C.
• Confident debugging using JTAG/SWD debuggers (J-Link, ST-LINK), logic analyzers, oscilloscopes, and protocol analyzers.
• Ability to read and work from schematics, hardware datasheets, and register maps to implement and validate drivers.
• Version Control: Git with Gerrit, GitHub, or GitLab workflows; branching strategies (Gitflow, trunk-based); mandatory code review via pull/merge requests.

Preferred Skills

• Experience with wearable, mobile, robotics, AR/VR, or ambient computing platforms.
• Familiarity with Android/Linux sensor frameworks.
• Prior experience supporting ASIC definition and silicon development cycles.
