This is not a maintenance or support role; You will be involved in building real products - from initial concept through to deployment - working alongside electronics and hardware engineers to deliver innovative solutions used in healthcare, medtech, sensors, wearables, and industrial environments. You will contribute to the full software lifecycle, including application development, cloud-based systems, and (where applicable) AI-enabled solutions. This role offers rare exposure to the complete journey from prototype to market, including integration with hardware, sensors, and embedded systems. Hybrid working is supported, typically three days per week on-site, with flexibility depending on project needs.What You'll Be Responsible For:Product & Software DevelopmentDesign, build, and deliver software products from concept through to productionContribute to full-stack development across backend services, web, and mobile applicationsWork closely with electronics and hardware engineers to integrate software with physical devices and sensorsCore Technology StackDevelop backend systems and applications using Python (essential)Build user interfaces and applications using React and React NativeContribute to cloud-hosted web applications, ideally using Node.js or similar technologiesAI & Advanced Software (where applicable)Contribute to AI-enabled applications, including data-driven and intelligent systemsSupport model training, fine-tuning, and deployment where experience allowsWork with tools and approaches such as:MLflow and model lifecycle toolsGradient boosted trees or custom model developmentAI application frameworks (e.g. LangChain, RAG-style architectures)Experience across both AI application developmentandmodel development is highly desirable, though not essential.Collaboration & DeliveryWork within a small, highly capable multi-disciplinary teamTake ownership for delivering complex software components in a hands-on wayContribute to technical decision-making, architecture discussions, and solution designEngage across busy project environments with frequent collaboration and stakeholder interactionAbout You: You are a hands-on software engineer who enjoys building products rather than maintaining legacy systems.
