Embedded Software Engineer
Embedded Software Engineer – Wearable Tech | London (On-site)
We're building next-generation wearable sensor technology that goes far beyond standard metrics giving people deeper, more accurate insight into how they move. To do that, we need engineers who care about getting it right.
We're looking for a Mid-Level Embedded Software Engineer to take real ownership of firmware development across our BLE-enabled wearable platform. You'll work closely with hardware, app, and data teams to build reliable, low-power systems from prototype through to production.
What You'll Be Doing
- Leading BLE firmware development stack implementation, advertising and connection strategies, low-power optimisation
- Writing clean, well-structured embedded C/C++ (Zephyr/FreeRTOS or bare-metal) with a strong grasp of state machines and peripheral management
- Owning data synchronisation between BLE devices and iOS/Android, including robust handling of connection interruptions and packet loss
- Collaborating with hardware engineers on peripheral validation (I2C/SPI, sensors, power management) and PCB bring-up
- Using oscilloscopes, logic analysers, and power profilers to debug and resolve firmware and hardware issues
What We're Looking For
- 4–6 years of embedded C/C++ experience on resource-constrained systems
- Solid BLE development background with demonstrable low-power implementation experience
- Experience taking a product through multiple development stages — wearable, IoT, or similar
- Zephyr RTOS preferred; FreeRTOS or bare-metal experience equally considered
- Comfortable owning work end-to-end with minimal hand-holding
- Python scripting or sensor interfacing experience is a bonus
- Git and CI familiarity expected
If you're an embedded engineer who's tired of maintaining legacy systems and wants to build something from the ground up we'd love to hear from you.
