Responsibilities
- Architect, design, implement, test, and maintain embedded software for automotive telemetry gateways and intelligent battery sensors.
- Develop bare-metal C/C++ firmware for ARM Cortex-M microcontrollers and real-time applications using Zephyr RTOS and FreeRTOS.
- Create board support packages, boot code, peripheral drivers, hardware-abstraction layers, linker/startup code, and low-level hardware interfaces.
- Build and maintain custom embedded Linux distributions with the Yocto Project, including BitBake recipes, layers, kernel and bootloader integration, device trees, images, and update strategies.
- Develop Linux userspace services and LTE-connected applications for automotive gateways.
- Design coordination between Linux, RTOS, and NPU domains using RPMsg, OpenAMP, shared memory, IPC, and vendor frameworks.
- Integrate and optimize machine-learning inference workloads on NPUs and other edge accelerators.
- Develop telemetry acquisition, processing, storage, secure cloud communication, diagnostics, logging, watchdog, recovery, and over-the-air update capabilities.
- Develop intelligent battery-sensor firmware and support SOC/SOH estimation using battery-monitoring measurements and algorithms.
- Integrate LTE modems, GNSS receivers, sensors, vehicle networks, and gateway peripherals.
- Analyze performance, memory, timing, power, and communications reliability, and debug hardware, firmware, operating-system, and multicore issues.
- Produce requirements, architecture, interface, design, and verification documentation; conduct reviews and mentor embedded developers.
- Collaborate with systems, hardware, cloud, data science, cybersecurity, validation, manufacturing, and product teams through prototype, vehicle testing, launch, and field resolution.
- Travel up to 10% may be required.
