About the role

We’re looking for a Senior Full Stack .NET Developer who can take a business problem from requirement through to production. You’ll build and support transactional systems and apply AI to real delivery work. You’ll work closely with business stakeholders, so you need to be as comfortable talking to them as you are writing code.

Essential
Proven full stack development experience with .NET/C# on the back end and Angular and/or React on the front end, delivering production-quality features end to end
Robust SQL skills, with solid relational database design and data modelling experience, including writing effective queries and designing schemas that scale and stay maintainable
Hands-on experience building and consuming APIs and integrations, including connecting with third-party and internal systems
Strong understanding of API and application security, including implementing authentication and authorisation with OAuth
Robust business analysis and communication skills, with the ability to elicit requirements, clarify ambiguity, and explain technical decisions to non-technical stakeholders
Experience working on enterprise transactional systems where accuracy, reliability and data integrity matter
DevOps experience,



including building and maintaining CI/CD pipelines and writing automated tests (unit, integration and end to end) to ship with confidence
Demonstrable AI design, development and delivery experience, with real examples of AI-enabled solutions you have taken from concept into production

Highly desirable
Node.js and Python experience
Azure or AWS cloud experience, including deploying and running applications in the cloud
Experience in health insurance, claims, financial services or another highly regulated domain, with an understanding of compliance, auditability and data privacy expectations
Production support and observability experience, including monitoring, logging, alerting and troubleshooting live systems
Experience with RAG (retrieval-augmented generation) and AI agents

Must-have behavioural traits
Ownership mindset: you take responsibility for outcomes, follow work through to completion, and raise issues early rather than waiting to be asked
Solid problem solving: you break down complex or unclear problems, weigh trade-offs, and land on practical, well-reasoned solutions
Learning ability: you pick up new tools, domains and AI techniques quickly and apply them with confidence
