About the role:
The Backend Developer (.NET/C#) – CMDB engineer is accountable for both the technical architecture and operational integrity of the platform governing infrastructure capacity, availability, asset lifecycle, and licensing across private cloud, public cloud, and datacenter environments.
We are primarily looking for a hands-on Backend Developer who is passionate about building integrations, services, and data solutions.
The ideal candidate has strong .NET/C# development skills, excellent SQL knowledge, and experience integrating enterprise systems through APIs.
