• Hands-on RTOS exposure (FreeRTOS or similar).
• Sound knowledge of CAN, UART, SPI, I2C interfaces.
• Familiar with TCP/UDP and UDS diagnostics.
• Experience with 32-bit ARM Cortex-M MCUs.
• Exposure to automotive processors like NXP S32G/S32K is a plus.
• Hardware debugging using oscilloscope, multimeter, and power supply.
• Basic electronics understanding; Python for automation is a plus.

Responsibilities

• Design, develop, integrate, and test embedded firmware for automotive ECUs.
• Develop firmware in RTOS environments, managing timing and resources.
• Work on Embedded Linux Kernel programming and low-level firmware tasks.
• Develop diagnostic and self-test functionality (POST, BIST, DTCs).
• Implement safe-state and fault-detection mechanisms for automotive systems.
• Develop and debug CAN, UART, SPI, and I2C communications.
• Work with CAN/Ethernet, including logging and diagnostics.
• Support higher-level diagnostics (TCP/UDP and UDS).
• Create firmware utilities and stress-test functions for validation.
• Perform hardware bring-up, debugging, testing, and root-cause analysis.
• Collaborate with hardware, software, and test teams on validation.
• Apply automotive functional safety and security concepts during development.
