As a Senior Software Engineer (AI / .NET), you’ll play a hands-on role in designing, building, and integrating AI-powered functionality into a live, customer-facing product.

You’ll work closely with engineers, product, and stakeholders to turn AI capability into real business value — focusing on production-ready solutions rather than proof-of-concepts.

Key Responsibilities

• Design and develop high-quality software using C# / .NET
• Build and integrate AI features into an existing product ecosystem
• Work with AI services, models, or LLMs (build, consume, or integrate)
• Ensure AI functionality is secure, scalable, and maintainable
• Collaborate on architectural decisions and technical direction
• Review code, mentor colleagues, and contribute to engineering best practices
• Take ownership of features from idea through to production release

What We’re Looking For

• Strong commercial experience as a Senior .NET / C# Developer
• Proven experience building or integrating AI features in production
• Experience working with AI/ML services, APIs, or LLM platforms
• Solid understanding of software design principles and clean architecture
• Comfortable working in a product-led, agile environment
• Able to balance innovation with robustness and user impact

Nice to Have

• Experience working on customer-facing products
• Exposure to data pipelines, prompt engineering, or AI optimisation
• Interest in shaping how AI is adopted across a wider product suite

Why Join?

• Work on a well-established product with a strong market presence
• Be part of the journey as AI becomes a core part of the platform
• Join a collaborative engineering team with real influence
• Competitive salary, benefits, and flexible working
