What you will do: Engineering \& Delivery * Design, build, and ship AI-powered features that improve clinical decision-making, patient outcomes, and operational efficiency. * Own the end-to-end feature lifecycle: prototype, production code, deployment, and post-launch optimisation, ensuring quality, performance, and measurable impact. * Work directly with clinicians and customers to turn real-world problems into working software, iterating quickly on live feedback. * Collaborate with other engineers to keep solutions technically sound, scalable, and maintainable. Applied AI * Evaluate emerging AI technologies, prototype rapidly, and define implementation approaches with a bias toward shipping. * Translate ambiguous opportunities into concrete technical requirements and working systems.
