AI & Backend Developer

Job description

[Employer hidden] Company develops high-fidelity medical simulators that blend precision hardware, immersive XR software, and cloud-connected AI to improve clinical training worldwide. We are expanding our team with a versatile AI & Backend Developer who can design scalable backend systems, integrate AI/ML, build polished Apple apps, and deliver outstanding user experiences for clinicians globally.

Main Duties:

• Design and build scalable backend services (REST, GraphQL) using Python, Node.js, PHP/Laravel; migrate legacy systems into containerised microservices.
• Develop native iOS/iPadOS apps (Swift, SwiftUI), including BLE connectivity, Core Data, and enterprise app distribution.
• Lead end-to-end UX/UI development for mobile and web dashboards, including clinical workflow mapping, wireframing, high-fidelity Figma prototyping, and pixel-perfect production interfaces that follow Apple HIG and WCAG 2.2 accessibility standards.
• Integrate AI/ML models (LLMs, vision models, classical ML) for both cloud services and on-device inference (Core ML, TensorFlow Lite); conduct A/B testing to evaluate educational outcomes.
• Build real-time data pipelines ingesting metrics from sensors, IoT devices, and user interactions, enabling instructor dashboards and trainee performance analytics.
• Collaborate with Unity/Unreal teams to expose secure APIs, WebSocket streams, and SDKs for real-time simulation synchronisation.
• Prototype AR/VR experiences using ARKit, RealityKit, or Unity AR Foundation to visualise anatomy, telemetry, and AI-guided feedback.
• Run user research with clinicians, iterate on usability findings, and champion inclusive design practices.
• Manage DevOps and cloud infrastructure (Terraform, GitHub Actions, Docker/Kubernetes, AWS/Azure/GCP) alongside observability tooling (Prometheus, Grafana, ELK stack).
• Implement security and compliance best practices (OAuth 2.0, JWT, GDPR, ISO 27001, NHS DSPT).
