Embedded Software Engineer


We are building the next generation of hearing-test technology that enables easier access to care for patients. We recently closed our first funding round and are now looking to grow our team to push our product to market.

As part of a small and dynamic team, you will contribute to the technical design, implementation, testing, and deployment of the product, and you will see your contributions rolled out worldwide.


Our test uses a spatial paradigm, wherein the patient listens to spatially-localised sounds, simulated in real-time using headphones and inertial measurement sensors, and is instructed to turn their head to face towards the perceived sound direction. By analysing patient head movements, we can determine which sounds the patient actually heard, and we can do so with greater reliability than has been achievable to-date by previous test paradigms.

Our technology stack includes: C++17, Linux (development machines), Android (UI, deployment platform), ARM SoC (audio synthesis + sensor integration), flatbuffers, cmake, git, and Spack (package management).

About the Role

We're looking for an Embedded Software Engineer (senior positions also available) with a strong background in embedded systems to develop and maintain our real-time spatial sound simulation system. Your first project will be in transforming our existing C++17 user-space Linux application into firmware for our purpose-built embedded hardware platform.

Your responsibilities will include:

About you

We're looking for a motivated and creative individual who is excited to work and contribute to a team that faces dynamically evolving technical challenges, requiring rapid independent learning and skill development. You must have a genuine passion for software engineering and be able to tell us of your adventures from previous projects.


About Hearing Loss

Hearing loss can have an immensely negative impact on an individual’s life, putting those affected at risk of becoming socially isolated, suffering from depression and anxiety, and developing dementia prematurely.

Providing access to care (hearing aids) can prevent these comorbidities, but it needs to be provided early. Screening tests act as the gatekeeper for providing this care, but existing tests are notoriously unreliable, leaving as many as 2 out of 10 patients with the wrong diagnosis.

We have developed a more reliable test and our vision is to now make hearing testing as commonplace and accessible as eye testing, ensuring that everyone in need receives care at the earliest possible opportunity.


Salary is between £25k and £45k, depending upon ability and experience.

Additional Information

We're embracing the remote-working culture and will need you to be committed to working from home for at least the next 12 months. You are welcome to live and work from anywhere within the UK, and will not be required to relocate, even after the pandemic ends.

Eligibility and How to Apply

For consideration, you must be legally eligible to work in the UK. Please send your CV and cover letter to Colin Horne (, showcasing as many of your previous projects as possible. Where your previous projects were undertaken as part of a wider team, please describe your individual role and contributions.
