Senior Product Engineer – C#/.NET & AI
Nottingham | Hybrid – 3 Days Office
We're hiring a Senior AI Software Engineer for a global enterprise software organisation currently scaling its AI engineering capability across the UK.
You'll join an established product engineering environment where AI is being embedded directly into commercial software used by real customers - rather than sitting within an isolated R&D or innovation function.
We're looking for a Full-Stack C#/.NET Software Engineer with genuine hands-on Applied AI experience.
What you'll be doing
- Building AI functionality into established commercial products
- Hands-on development across C#/.NET, APIs, frontend and databases
- Integrating cloud-hosted LLMs/models into applications
- Potentially working with local/self-hosted models
- Rapidly prototyping new AI capabilities
- Implementing appropriate security, validation and model guardrails
- Working with Product and Engineering to move ideas into usable software
- Using modern AI development tooling to accelerate delivery
Technology
C# | .NET | ASP.NET Core | React/Angular/Next.js | SQL Server/PostgreSQL | Azure/AWS | LLMs | OpenAI/Claude | Git | CI/CD
What we're looking for
Strong commercial C#/.NET engineering is essential, alongside credible full-stack development experience.
You'll also need to demonstrate that you've personally built AI into a product or solution.
We're not looking for someone whose AI experience is limited to asking ChatGPT questions or using Copilot/Cursor to generate code.
Around 1–3+ years of commercial AI exposure would be attractive, although candidates with less experience can absolutely be considered where they can demonstrate substantial hands-on AI product delivery.
Experience with local LLMs, model security/guardrails, RAG, agents, prompt/context engineering or evaluation would strengthen your profile.
