• Building AI agents that retrieve information, process documents and take controlled actions, with appropriate validation and human approval.
• Developing APIs, backend services and integration components using C#, modern .NET, ASP.NET Core and Azure Functions.
• Connecting business applications through REST APIs, webhooks and custom connectors.
• Creating maintainable automation using Power Automate, Dataverse and Power Platform.
• Selecting the right approach for each requirement, balancing conventional software development with low-code tools.
• Implementing secure authentication and access using Entra ID, OAuth 2.0 and managed identities.
• Establishing reliable testing, monitoring, logging and deployment practices.
• Helping define technical standards and mentoring colleagues building internal automations.

Your background should include:

• Strong C# and modern .NET development, including ASP.NET Core Web APIs and backend services.
• Azure development, including Azure Functions.
• REST APIs, HTTP, JSON, OpenAPI/Swagger and webhooks.
• Integration patterns covering authentication, pagination, rate limits, retries and exception handling.
• Microsoft Entra ID, OAuth 2.0, application permissions and secure secrets management.
• Git, CI/CD pipelines, automated testing, monitoring and production support.
• Clear communication skills and the confidence to own technical decisions.

Experience that would be useful

Hands-on experience with Copilot Studio, Power Automate, Power Fx or Dataverse would be particularly valuable. Strong .NET and Azure engineers with the aptitude and enthusiasm to develop these skills are also encouraged to apply, with support available.

Other useful experience includes:

• Microsoft Graph, Teams and SharePoint integrations.
• Azure AI services, document processing and retrieval-based solutions.
• Logic Apps, API Management, Service Bus and Key Vault.
• TypeScript, JavaScript or Python.
