Job Description

Overview

Bioliberty is on a mission to give everyone the best chance at recovery from a mobility-limiting condition or injury so they can reclaim their independence.

Founded in 2020, we've raised $7 million from a mix of public and private investors and launched our first product to the U.S. healthcare market in May 2025. We hold seven patents across our core technologies, Lifehub and Lifeglov -- both of which are FDA-registered.

We're now entering an exciting new phase of growth and are looking for a talented Firmware Engineer (mid-level) to join our team.

In this role, you'll design, develop, and optimise firmware solutions for our embedded systems, playing a critical part in product innovation and performance. Your work will involve real-time interaction with hardware, as well as wireless and wired communication with companion mobile applications.

This is a unique opportunity to develop technology that makes a real-world impact, helping improve patient outcomes and enabling clinicians to deliver more effective and engaging therapy.

The role is based at our headquarters in the National Robotarium in Edinburgh--a world-leading centre for robotics, AI, and autonomous systems. Due to the hands-on nature of the work with physical hardware and test equipment, regular time in the office is expected, though we offer flexibility for remote work depending on workload.
