OUR client in ClimateTech seeks a hands‑on Technical Architect and Senior Backend Developer to take ownership of the platform’s end‑to‑end technical design and personally lead the build of its core Backend services. You will be the design authority for its Azure‑native, microservices‑based architecture and a Senior Engineer writing C# code in the cluster — equally comfortable in a whiteboard session with stakeholders, in a code review on a plugin assembly, and in a war‑room debugging a production data ingestion job. The successful candidate must have 8+ years of professional Software Engineering with at least the last 4 in a Senior, Architect, or Tech‑Lead capacity on production cloud systems. You will also require deep C# and .NET expertise: .NET Core / .NET 6+ (and ideally .NET 8/10), ASP.NET Core, EF Core, async/await fluency, performance tuning, and modern C# language features.
