Location: Central London, UK (with potential for travel across Europe)

About Us
XRnostics is an exciting, innovative spinout company born out of a world-class research collaboration between King's College London and Guy's and St. Thomas' NHS Foundation Trust. We bring together leading clinical experts and world-class imaging scientists to revolutionize education, training, and the planning of cardiac procedures using immersive imaging.
Our mission is to pioneer advanced virtual reality (VR) and augmented reality (AR) solutions for hospital sites within the UK and across Europe, medical device companies, and the medical education sector. We are currently expanding our international, diverse team with talented and motivated engineers looking for meaningful, long-term career prospects.
To further develop our flagship product, HeartVR™, for commercialization, we are looking for a Software Engineer (m/f/d) to join us for an initial 6-month period (with a view to extension).
Your Responsibilities
In this role, you will bridge the gap between advanced backend architecture, immersive VR/AR visualization, and real-world clinical deployment.
- Core Development: Further develop and optimize the backend and user experience for our core VR/AR software platform.
- Feature Engineering: Deliver critical software engineering aspects, including QMS compliance, software specification, seamless dataset loading, advanced rendering, and scene manipulation.
- Usability & UX: Enhance XR usability by creating interactive training tutorials and streamlining deployment pipelines.
- Clinical Deployment & Roadshows: Take the product directly to clinical testing sites in the UK and mainland Europe. You will handle software installation, provide hands-on user training, and collaborate closely with medical professionals.
- Feedback Loop: Collect direct feedback from clinical users and directly implement required or desired features into the product roadmap.
