Firmware System Engineer

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 optimisation 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 optimisation, and working across the entire embedded stack, from board bring-up to wireless protocols and sensor data management.

Responsibilities:

• Develop, test, and maintain embedded firmware for custom hardware platforms, with a strong focus on BLE-based communication systems.
• Integrate and optimise sensors such as IMUs, accelerometers (digital and analogue), and other low-power peripherals.
• Work with flash file systems, bootloaders, and memory management strategies for efficient data handling.
• Drive power optimisation efforts across firmware, including deep sleep modes, peripheral management, and runtime tuning.
• Contribute to antenna and RF performance optimisation in collaboration with hardware and RF teams.
• Support synchronised 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.

Requirements:

• 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 analysers, and protocol sniffers.
• 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, synchronised 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 analogue accelerometers and their trade-offs in embedded systems.
