We are looking for an experienced Firmware Embedded Developer to design and develop firmware for fitness/wearable devices, with a strong focus on Bluetooth Low Energy (BLE) integration with mobile applications. The role involves developing low-power embedded solutions, integrating with NDK/SDK layers, and collaborating closely with mobile app teams to deliver seamless user experiences.

Key Responsibilities :

- Design, develop, and optimize firmware for fitness/wearable devices.

- Implement and maintain BLE communication protocols for Android/iOS integration.

- Collaborate with mobile developers to ensure smooth interaction via NDK/SDKs.

- Work with hardware teams on sensor integration (accelerometer, heart-rate, SpO2, etc.).

- Debug and resolve firmware, connectivity, and performance issues.

- Support OTA firmware updates and SDK documentation for third-party integration.

- Ensure low-power consumption and high reliability in embedded systems.

Requirements :

- Bachelors/Masters in Electronics, Computer Science, Embedded Systems, or related fields.

- 3-5 years of hands-on experience in firmware development.

- Proficiency in C/C++ for embedded systems.

- Strong knowledge of microcontrollers (ARM Cortex, Nordic nRF, ESP32, or similar).

- Solid understanding of Bluetooth Low Energy (BLE) stack and GATT profiles.

- Experience with NDK/SDK integration and API communication with mobile apps.

- Familiarity with RTOS, low-power design, and hardware debugging tools (JTAG, oscilloscopes, analyzers).

- Strong debugging, problem-solving, and cross-functional collaboration skills.

Good to Have :

- Experience in fitness/wearable device firmware.

- Knowledge of OTA updates, secure firmware design, and mobile BLE integration (Android/iOS).

- Exposure to cloud connectivity for IoT devices.
