Full job description

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
