Marketing Cloud Engagement System Admin

About Us We're a nonprofit organization running Salesforce (Sales Cloud + Nonprofit Success Pack) integrated with Salesforce Marketing Cloud Engagement (MCE) in a multi-Business Unit setup (parent BU handles the Salesforce sync, child BU handles sends). I'm the sole Salesforce admin/developer on our team, and while I'm comfortable in Salesforce, I need an MCE specialist to help diagnose and fix some sync and subscription management issues that are outside my depth. The Problems We Need Help With Salesforce ↔ Marketing Cloud Sync We maintain marketing lists in Salesforce and sync contacts into Data Extensions in MCE. We need someone to evaluate whether this sync is architected correctly and identify any gaps or inefficiencies. Unsubscribe Handling We're having issues with how unsubscribes are being handled and reflected back in Salesforce. We need someone to diagnose the root cause and help us implement a reliable, sustainable fix. What We're Looking For Proven hands-on experience with Salesforce Marketing Cloud Engagement, especially Contact Builder, Data Extensions, Publication Lists/Subscriber Lists, and Journey Builder Experience with Salesforce-to-Marketing-Cloud sync configurations (Marketing Cloud Connect or similar), ideally in a multi-BU environment Strong understanding of subscriber status, suppression lists, and unsubscribe handling in MCE, and how that data is (or isn't) synced bidirectionally with Salesforce Comfortable working alongside a Salesforce admin (me) to explain findings clearly — I can implement Salesforce-side changes, but need expert guidance on the Marketing Cloud side Nonprofit/NPSP experience a plus, but not required Scope of Work Phase 1 – Audit (fixed initial engagement) Review current MCE setup: BU structure, Data Extensions, Publication Lists, sync configuration Diagnose the root cause of our unsubscribe handling issue Deliver a written summary of findings with recommended fixes, prioritized by impact/effort Phase 2 – Implementation (ongoing hourly) Fix the unsubscribe handling issue Correct or rebuild sync architecture as needed Optional: light documentation/knowledge transfer so we can maintain this going forward To Apply, Please Include Relevant experience with Marketing Cloud Engagement sync and subscriber/suppression management A brief description of how you'd approach diagnosing sync and unsubscribe issues like these Your hourly rate and general availability Looking forward to hearing from you!
