• Develop responsive frontend applications alongside robust APIs and backend services to create seamless user experiences.
• Work closely with Product, Business Change and business stakeholders to translate requirements into technical solutions.
• Design reusable components and architecture that can support future AI initiatives across the organisation.
• Ensure solutions are secure, well-tested, maintainable and aligned with engineering best practice.
• Provide technical leadership, mentoring and guidance to colleagues whilst remaining hands-on with development.
• Support and continuously improve production services, identifying opportunities to enhance performance and business value.

Skills & Experience:

• Extensive experience developing applications using C#/.NET and modern frontend frameworks such as React or Angular.
• Experience designing and building REST APIs and integrating AI capabilities into enterprise applications.
• Strong knowledge of Microsoft Azure, including Azure AI Foundry, Azure AI Services and cloud-native application development.
• Experience implementing AI solutions including LLM integration, prompt engineering, Retrieval-Augmented Generation (RAG) and vector databases.
• Experience working with SQL and NoSQL databases, with knowledge of platforms such as SQL Server, Snowflake, OneLake or similar data platforms.
• Strong understanding of software architecture, scalability, CI/CD, DevOps and engineering best practices.
• Experience working within Financial Services or another regulated environment would be advantageous.
• Excellent communication skills with the confidence to work directly with business stakeholders and explain complex technical concepts.
• A collaborative, hands-on approach with a product mindset, enjoying working as part of a team to deliver practical AI solutions that create genuine business value.
