About The Role

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.
