Your mission: We’re developing next-generation wearable sensor technology that captures far more than standard metrics. Our goal is to give people deeper, more accurate insights into how they move.
Your Role: As a Junior Embedded Software Engineer with 2–3 years of experience, you’ll contribute to building and improving our firmware across a range of BLE-enabled wearable devices. Working alongside hardware, app, and data specialists, you’ll help optimise low-power BLE systems and develop reliable firmware features. This is a hands-on role with real ownership and plenty of room to grow.
Responsibilities:
- BLE Firmware Development: Contribute to BLE stack development, supporting robust performance and low-power operation. Implement and refine advertising and connection strategies under the guidance of senior engineers.
- Low-Power Firmware: Write clean, well-structured embedded C/C++ (FreeRTOS or bare-metal), using state machines and peripheral management to help maximise battery life.
- Communication Protocol Implementation: Implement data synchronisation between BLE devices and smartphones (iOS/Android), handling connection interruptions and packet loss with support from the wider team.
- Hardware/Firmware Interface: Work with hardware engineers to validate peripherals (I²C/SPI buses, sensors, power management) and contribute to PCB bring-up at the prototype stage.
- Debug & Testing: Use oscilloscopes, logic analysers, and power profilers to identify and resolve firmware and hardware issues.
Your profile: What We’re Looking For:
- 2–3 years of embedded C/C++ experience on resource-constrained systems.
- Hands-on BLE development experience, with exposure to low-power implementations.
- Exposure to at least one product or project through multiple development stages (wearable, IoT, or similar).
- Familiarity with BLE-to-smartphone communication on iOS or Android, including basic data synchronisation and error handling.
- Zephyr RTOS preferred; FreeRTOS or bare-metal background also considered. We’re happy to bring you up to speed on Zephyr if needed.
- Comfortable using standard debug tooling (oscilloscope, logic analyser, power measurement).
- Basic Python scripting or sensor interfacing experience is a plus.
- Familiarity with Git and CI workflows is a plus.
Why us? Why You’ll Love Working With Us:
- Work on truly meaningful tech with real impact.
- Collaborative and friendly team environment.
- Competitive salary and benefits.
- Strong mentorship and room to grow technically.
- Hybrid working with a Paddington-based office.
