About This Role This role sits at the intersection of CRM architecture and technical delivery, specifically focused on migrating clients from Salesforce and other enterprise CRMs into HubSpot. Partner agencies are winning more Salesforce-to-HubSpot migration deals than ever — driven by a significant cost gap between platforms — and the bottleneck is always the same: finding someone who actually knows how to execute the technical migration cleanly.
