Client Onboarding & Support Specialist

WealthArc is a global financial data infrastructure company. We connect wealth managers, external asset managers, family offices and banks to their custodian data and turn it into clean, usable portfolio information through our platform: Connector, WealthArc Data Box (WDB), WISDOM, Prism and Creator, plus our PMS, Viewer and agentic AI applications.

As a Client Onboarding & Support Specialist, you will be the client's guide from contract signature to go-live.

Alongside onboarding, you are the backup for our Customer Success and client support function.
