Junior .NET Software Engineer

Explore Learning is a leading educational organisation that is committed to making learning enjoyable and effective for children. With our network of learning centres across the country and our online tutor offering, we help thousands of children develop their skills and reach their full potential. 

We're looking for a junior backend engineer to design, build, and operate cloud-native services on Azure. You'll own systems end-to-end — from C# code through to the Azure infrastructure they run on — and work alongside AI coding agents as part of how we ship. 

What you'll do 

• Build and maintain backend services in C# / .NET (8+) 

• Design and evolve data models in Azure SQL Server, including performance tuning and migrations 

• Implement event-driven and asynchronous workflows using Azure Service Bus (queues, topics, sessions, dead-lettering) 

• Work with Azure Storage Accounts (Blob, Queue, Table) for durable storage and integration patterns 

• Use AI coding agents (e.g. Claude Code, Copilot) as part of your daily workflow — scoping tasks, reviewing agent output, and shipping production code with them in the loop 

• Write clean, testable code with solid unit and integration test coverage 

• Contribute to CI/CD pipelines, observability, and production support 

Must-haves 

• Strong C# / .NET backend experience (3+ years) 

• Hands-on production experience with Azure SQL Server — schema design, T-SQL, indexing, query plans 

• Hands-on production experience with Azure Service Bus — messaging patterns, idempotency, retries, poison messages 

• Hands-on production experience with Azure Storage Accounts — Blob and Queue at minimum 

• Practical exposure to agentic software development — using LLM-based coding agents (Claude Code, Cursor, Copilot, or similar) to plan, generate, and review code; understanding their strengths, failure modes, and where human judgment is non-negotiable 

• Comfortable with async/await, dependency injection, and modern .NET patterns 

• Familiarity with REST API design, authentication (OAuth2 / JWT), and structured logging 

Nice-to-haves 

• Experience writing prompts, agent instructions, or AGENTS.md / CLAUDE.md files for repo-level agent guidance 

• Building or integrating with MCP servers, tool-using agents, or LLM APIs 

• AKS / containerised workloads 

• Azure Functions, Durable Functions, or Container Apps 

• Infrastructure as Code (Bicep, Terraform) 

• Entra ID / Entra External ID 

• Datadog or similar observability tooling 

• Azure certifications (AZ-204, AZ-400, AZ-104) 

You'll thrive here if you 

Care about reliability and operability, not just shipping.

Like owning a service rather than throwing it over a wall.

Push back when the design isn't right — whether it came from a human or an agent.
