Senior .NET Developer AI & Intelligent Automation

Were working with a leading healthcare technology company, based in Chorley right next to Buckshaw Parkway railway station. This role will focus on designing and delivering AI-driven capabilities and intelligent automation within our core policy and claims management product, define and build new features that improve user productivity and automate high-volume, repeatable processes, particularly around claims invoice processing and related workflows.

You will work within a Scrum team (3-week sprints), contributing to our existing .NET/Angular platform while leading the design and implementation of AI-centric features and integrations. You will partner closely with our ML engineering and infrastructure teams to leverage our in-house GPU infrastructure and Run.ai platform for model training, fine-tuning, and inference at scale.

Key Responsibilities

Core Product Development (.NET / Angular / Messaging)

• Design, build, and maintain core product features using:
  • .NET (C#), ASP.NET Core
  • Angular
  • SQL Server and MongoDB
  • RESTful APIs and NServiceBus
• Contribute to application architecture decisions, refactoring initiatives, and shared platform components.
• Ensure new AI features are robust, secure, explainable, and integrated cleanly into the existing product.

AI Capability & Feature Development

• Work with Product Management and domain experts to identify high-value AI use cases, initially focusing on automating processing of claims invoice documents (e.g. OCR, document classification, data extraction, validation workflows).
• Design, implement, and integrate AI services and pipelines, such as Machine learning / rules-based components for classification, anomaly detection, and routing (e.g. flagging potentially incorrect invoices or exceptional cases).
• Fine-tuned language models or specialized inference models deployed on our in-house GPU infrastructure.

User Experience & Workflow Automation

• Work closely with Product and UX to design AI features that give clear benefits to end-users (time saved, errors reduced, fewer clicks).
• Implement workflow automation and orchestration:

Required Skills & Experience

• Strong commercial experience building enterprise applications with:
  • .NET / C#
  • ASP.NET Core
  • Angular
  • SQL Server and MongoDB
  • RESTful APIs; NServiceBus or equivalent service bus/messaging platform.
• Demonstrable experience in at least one of:
  • Implementing AI/ML-driven features in a production product, or
  • Building document processing / intelligent automation workflows (OCR, classification, extraction, validation).
• Familiarity with common AI/automation building blocks such as:
  • OCR and document understanding (e.g. cloud services or libraries).
  • Entity extraction, text classification, or similar NLP tasks.
  • Rule engines, workflow engines, or BPM/orchestration tools.
• Strong understanding of non-functional requirements for AI features:
  • Performance and throughput for high-volume processing.
  • Data protection, privacy, and access control.
  • Auditability, traceability, and explainability for automated decisions.
• Solid grounding in software engineering fundamentals: design patterns, testing strategies (unit/integration), CI/CD concepts, secure development lifecycle.

Personal Attributes

• Product-minded engineer who thinks in terms of user outcomes, not just technology.
• Pragmatic with AI: focused on solving real user problems and automating meaningful work, rather than technology for its own sake.
• Comfortable working in ambiguous problem spaces and iterating quickly based on feedback.
