Multi-skilled developer for innovative medical software Do you like getting your hands dirty solving tough, low-level system problems? Do you have a background developing web platforms? Does the idea of working at a startup appeal? With a small and ambitious technical team this startup has already demonstrated their prowess producing a personalised web-based health platform tested in conjunction with the NHS and now rolling out to patients. They are looking for skilled developers to join the team and help transform medical care in the UK and beyond. Their scalable technologies allow treatment plans to be personalised based on real-time patient data and delivered by video. This requires a serious range of technical knowledge from building kernel level (or below) systems up to web and mobile app front-ends and everything in between. The nature of a startup means they have limited resources, so they are seeking people with high-performance low-level systems experience along with a significant secondary skill. Perhaps that is TypeScript front-end development, but maybe it's more likely to be Python web back-end development or in-depth compiler knowledge. Whatever it is, this needs to be a significant second string to your bow as a developer. Requirements: Significant commercial experience building systems near or below kernel level. Additional working knowledge of WebRTC or similar real-time technologies would be highly beneficial. Strong knowledge of C++ or Rust. Additionally, knowledge of a functional language such as OCaml would be useful.A significant secondary commercial skill base. This should be one of the following or be closely related: Compiler development with DSLs Python web back end development TypeScript web front end development Mobile application development (native or otherwise) As a startup you can expect both variety and challenge in the work, and perhaps uniquely, you will get to meet the patients your software helps and understand importance of your work to them. Half the team are clinicians with years of medical knowledge and a thorough understanding of current norms and where improvements can have the largest impact. Remuneration is excellent and comes with comprehensive medical coverage, an on-site gym, and early-stage equity. All from a beautiful workspace in the Cambridgeshire countryside.
