You will be responsible for the end-to-end stewardship of assigned clients' service relationship from data onboarding through to service delivery, ensuring accuracy, continuity, responsiveness, and confidence in Cornspring’s service.
As the "custodian of client trust", you will own the client’s lived experience of the data on our platform and our service delivery to clients. You will make sure that client trust increases over time, not just satisfaction scores.

To be successful in this role, you need to have prior experience in client-facing roles within financial data or reporting firms, asset managers, wealth platform service providers, or large multi-family offices.
You need to be commercially aware and to be credible with investment and accounting operations staff at a family office, especially when working with CFO, CIO and Head of Operations profiles.
Your judgement needs to remain calm under ambiguity.
You need to be able to explain complex data behaviour simply.
