analyzers)

Firmware / Embedded Software Development

• Develop, maintain, and optimize embedded software in C/C++

• Build applications on RTOS (Real-Time Operating Systems) platforms such as

FreeRTOS, Zephyr, or custom schedulers

• Implement low-level drivers (UART, SPI, I2C, ADC, CAN, BLE, GSM/LTE)

• Integrate sensor, GPS, and communication modules

• Write robust, maintainable, and documented code following MISRA-C, embedded

coding standards, and internal best practices

• Conduct thorough unit testing, debugging, and firmware validation

Product Development & Testing

• Work closely with QA to create test procedures and participate in DFM (Design for

Manufacturing) and DFT (Design for Test)

• Collaborate cross-functionally with Software, UX/UI, and Mechanical teams during

product development lifecycle

• Create and maintain technical documentation: schematics, BOMs, firmware revision

history, test plans
