JOB: Embedded Firmware Engineer At MosChip In Ahmedabad

APPLY HERE

Location: Ahmedabad

Company: MosChip

We are looking for an Embedded Firmware Engineer with strong experience in RTOS-based embedded firmware development for wearable or IoT devices. The role involves developing firmware and middleware using Zephyr/FreeRTOS, integrating connectivity modules such as BLE, GPS, LTE, and interfacing with multiple sensors.

The engineer will also contribute to board bring-up, device driver development, and platform integration, with some exposure to Embedded Linux environments where required.

Responsibilities

• Design and develop embedded firmware using RTOS such as FreeRTOS, Zephyr, ThreadX, or similar, including task scheduling, synchronisation mechanisms, and inter-task communication.
• Design and develop embedded firmware and middleware for wearable devices using RTOS (Zephyr, FreeRTOS, or similar).
• Implement real-time tasks, scheduling, and power management for battery-operated systems.
• Integrate connectivity modules such as BLE, GPS, and LTE.
• Develop and integrate sensor interfaces and data processing for sensors such as IMU, heart-rate, temperature, and others.
• Develop and maintain device drivers and communication interfaces (I2C, SPI, UART, GPIO).
• Perform board bring-up activities, peripheral enablement, and debugging of hardware–software interaction issues.
• Work with Embedded Linux platforms when required, including basic BSP customisation or driver integration.
• Collaborate with hardware, mobile, and cloud teams for end-to-end product integration.
• Perform unit testing, debugging, validation, and firmware performance optimisation.
• Participate in code reviews and maintain technical documentation.
