About the Role :

We're looking for a Firmware / Embedded Systems Engineer with 3 to 5 years of hands-on experience in embedded development to support the design and optimization of cutting-edge low-power, sensor-driven wireless devices.

In this role, you'll be working on performance-critical systems involving BLE connectivity, real-time data processing, and custom hardware integrations.

This is a great opportunity for an engineer who enjoys digging deep into firmware performance, power optimization, and working across the entire embedded stack-from board bring-up to wireless protocols and sensor data management.

Key Responsibilities :

- Develop, test, and maintain embedded firmware for custom hardware platforms, with a strong focus on BLE-based communication systems.

- Integrate and optimize sensors such as IMUs, accelerometers (digital and analog), and other low-power peripherals.

- Work with flash file systems, bootloaders, and memory management strategies for efficient data handling.

- Drive power optimization efforts across firmware, including deep sleep modes, peripheral management, and runtime tuning.

- Contribute to antenna and RF performance optimization in collaboration with hardware and RF teams.

- Support synchronized data collection across multiple devices for real-time streaming and data logging applications.

- Collaborate with cross-functional teams including hardware, app, and data science to deliver seamless end-to-end product functionality.

Basic Qualifications

- B.Tech. or M.S. in Electronics Engineering, Embedded Engineering, or related discipline.

- 3-5 years of experience developing embedded firmware in C/C++ for ARM Cortex-M or similar microcontrollers.

- Proven experience with Bluetooth Low Energy (BLE) stacks and custom BLE services/profiles.

- Experience with IMUs, accelerometers, and integrating sensor data into real-time applications.

- Familiarity with flash memory, embedded file systems, and bootloaders.

- Strong debugging skills using tools like JTAG/SWD, oscilloscopes, logic analyzers, and protocol sniffers.

Preferred Qualifications

- Experience with Nordic Semiconductor devices and the nRF Connect SDK (NCS).

- Knowledge of low-power design principles and techniques for battery-operated devices.

- Background in RF/antenna tuning and wireless performance testing.

- Understanding of BLE live streaming, synchronized data collection, and time-stamping accuracy across devices.

- Familiarity with protocols like Find My, ANT+, or other proprietary wireless standards is a strong plus.

- Exposure to both digital and analog accelerometers and their trade-offs in embedded systems.
