The Role 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.
