The Custodian Relationship Manager serves as Vestmark's primary liaison between our internal teams and our external partners across Custodians, Asset Managers and Technology Vendors.

This role is responsible for maintaining and growing strategic relationships with major custodians through structured relationship building, proactive roadmap alignment, and technical integration oversight.

A critical and distinctive part of this role is building and owning the custodian playbook — a comprehensive, per-custodian operational guide that standardizes how Vestmark onboards new clients, configures integrations, and supports day-to-day operations across each custodial relationship.

Equally important is serving as the Vestmarkchampion for makingit easier for advisors to do business with Vestmark, by ensuring that custodian infrastructure and Vestmark's platform capabilities are seamlessly connected.

This is a highly cross-functional role that sits at the intersection of relationship management, technical program delivery, and operational coordination. The ideal candidate brings equalpartsrelationship acumen and technicalfluency, andthrives in an environment that requires both strategic thinking and hands-on execution.

• Build and maintain a comprehensive, per-custodian playbook that serves as Vestmark's authoritative operational guide for each major custodian relationship
• Document custodian-specific requirements for trading connectivity and RIA account onboarding.

• Partner with Advisory Solutions, Client Delivery, Operations and Production Support to validate and continuously improve playbook content based on lessons learned from live implementations
• Ensure playbooks are versioned, maintained in a centralized and accessible repository, and shared cross-functionally as a standard onboarding resource
