About The Role

We are looking for Embedded Software Engineers to build the low‑level intelligence that powers OmniBuds’ in‑ear sensing platform. You will work at the intersection of hardware, firmware, and sensing—developing robust, real‑time embedded systems for medical‑grade wearable devices operating in noisy, real‑world conditions.

Location

Cambridge, UK

Department

Research, Algorithms & Engineering

Employment Type

Full‑time | Hybrid

What you’ll do

• Develop and maintain embedded firmware for in‑ear earable devices (MCUs, sensors, BLE).
• Implement real‑time data acquisition pipelines for multimodal sensors (PPG, IMU, microphones, temperature).
• Optimise power consumption, latency, and memory for continuous sensing workloads.
• Work closely with hardware teams on board bring‑up, debugging, and system integration.
• Support prototyping, testing, and validation in lab and clinical study settings.
• Contribute to reliability, safety, and robustness of long‑running wearable systems.

What we expect

• Strong experience in embedded C/C++ for resource‑constrained systems.
• Hands‑on experience with MCUs, RTOS, and peripheral interfaces (I2C, SPI, UART).
• Familiarity with BLE and low‑power wireless communication.
• Experience debugging hardware/software interactions.
• Comfort working across firmware, hardware, and systems teams.

Why OmniBuds

At OmniBuds, you’ll build embedded systems that directly enable new forms of continuous cardiovascular monitoring. Your work will move beyond demos—into real clinical studies and real patient impact.
