We are a global alliance of 800\+ organizations across the connectivity ecosystem \- counting the world’s top 10 Communication Service Providers (CSPs) and all the key hyperscalers as active, strategic members. **About the role** We are looking for an experienced full\-stack .NET developer with considerable CMS experience to join our team on a freelance basis to help deliver bug fixes and change requests (CRs) against the TM Forum website — the primary online presence for a global industry association.
