C# Developer - AI

C# Developer – AI

We’re looking for a Senior Developer who can bridge strong C# engineering with modern AI capabilities.

This role sits at the intersection of traditional backend development and emerging AI-driven solutions. You’ll play a key part in evolving existing systems while introducing intelligent, data-driven features using AI agents and language models.

If you’re excited by using AI to solve real business problems, while still getting hands-on with robust C# development, this is a role where you can have real impact.

What you’ll be doing

  • Design, build and maintain scalable applications across the Microsoft technology stack, with a focus on C# and Azure
  • Develop intelligent features using AI agents to power dynamic reporting, automation, and decision support
  • Use language models to match, enrich and interpret data across multiple systems and datasets
  • Work on both internal and customer-facing platforms, improving performance, usability, and reliability
  • Enhance existing products while introducing new AI-driven capabilities
  • Collaborate with analysts, developers and business stakeholders to identify where AI can add value
  • Take ownership of technical solutions from concept through to delivery
  • Mentor developers and share knowledge across both traditional engineering and AI approaches
  • Contribute to architecture decisions, particularly around integrating AI into existing systems

What you bring

  • Strong experience with C# and MS SQL Server in a commercial environment
  • Experience building cloud-based solutions using Azure services such as Functions, Storage and Service Bus
  • Practical experience working with AI tools, ideally including:
  • AI agents or autonomous workflows
  • Large language models (LLMs)
  • Prompt engineering or structured output generation
  • Data matching, enrichment or transformation using AI
  • Ability to design systems that combine deterministic code with AI-driven logic
  • Strong understanding of data structures, APIs and system integration
  • Experience working with N-tier architectures and scalable systems
  • Solid understanding of version control (Git) and CI/CD pipelines, ideally within Azure DevOps
  • A problem-solving mindset with the ability to balance innovation with practical delivery

Nice to have

  • Experience with vector databases or semantic search
  • Exposure to tools such as OpenAI, Azure OpenAI, or similar AI platforms
  • Experience building reporting or analytics platforms
  • Knowledge of Kubernetes or containerised deployments

Why join

You’ll be working on systems that are actively evolving, with the opportunity to shape how AI is used across the business. This is not a research role. It is about applying AI in practical, high-impact ways within real products.

You’ll be part of a collaborative team where ideas are valued and where there is genuine investment in keeping your skills current across both engineering and AI.
