About this role
BlackRock is seeking an Associate to support data stewardship for the Assets & Opportunity data domains within the BlackRock Data Office (BDO), as part of the Assets & Opportunity Data Stewardship team.
The BDO, part of Aladdin Data, accelerates how data is onboarded, governed, managed and consumed through the firm’s Enterprise Data Platform, so that trusted, reusable and AI-ready data can be managed as a strategic enterprise asset supporting operational excellence, analytics, AI innovation, and our 2030 strategy.
As a data steward in the Assets & Opportunity pillar, the Associate will help deliver a trusted client-level and business-specific view of assets under management (AUM), net new assets and client wallet data to the global enterprise, working with Client Business COOs, the Global Product Solutions organization, and Finance.
The role supports the sourcing and delivery of the data behind this view across AUM & Flows and Walletshare (the share of a client’s total assets that BlackRock manages versus competitors), with focus on one or both areas depending on team needs: helping onboard and validate data from third-party providers, distributors and home offices, investigating exceptions, and partnering with internal stakeholders and technology teams to ensure the data is accurate, timely and discoverable and that client flows are attributed to the correct client, product, and client business.
Key Responsibilities:
The Associate will provide day-to-day stewardship and operational support for the Assets & Opportunity pillar under the guidance of Data Stewardship leadership. Responsibilities include:
- Stewardship Support: Support the domain steward in executing data stewardship for AUM & Flows and/or Walletshare, including maintaining business definitions, critical data elements, data quality rules and supporting documentation.
- AUM & Flows Data Support: Monitor and reconcile AUM and flows data, investigate attribution gaps, discrepancies and breaks, and work with data and technology partners to correct and explain differences in a timely manner.
- Walletshare Data Support: Support the onboarding, mapping and validation of third-party and competitor wallet datasets to client, entity and product identifiers; research and maintain client wallet information across a variety of sources; and help ensure usable client-, advisor- and office-level wallet signals reach sales and analytics teams.
- Data Quality & Exception Monitoring: Run data health assessments and exception reporting (e.g., refresh timeliness, level of client attribution), triage and resolve exceptions with BDO Data Operations, and escalate recurring issues for root cause analysis and remediation.
- Data Sourcing & Vendor Coordination: Coordinate with third-party data vendors, distributors and home offices on data delivery, file issues and changes, and help ensure sourced data is accurate, timely and aligned to business needs.
- Business Requirements & Stakeholder Partnership: Document data requirements, support testing of enhancements and partner with Client Business COOs, Global Product Solutions, Finance and Aladdin Engineering, escalating risks and priorities to Data Stewardship leadership as needed.
- Reporting & Sales Enablement: Maintain and enhance reporting and dashboards that enable sales and product teams to use AUM & Flows and Walletshare data in support of sales targets.
- Process Improvement & Automation: Identify and help deliver process improvements and opportunities to use automation and AI agents for file monitoring, data quality alerts, exception resolution and rule documentation.
- Communication & Collaboration: Prioritize effectively across stakeholders in an agile environment, and communicate outcomes and operational risks clearly to senior colleagues.
Qualifications & Requirements:
Required:
- 2+ years of relevant experience in data management, data operations, data governance, data stewardship or a related analytical role, ideally within financial services.
- Working knowledge of SQL and Excel, and of PowerBI or other analysis and reporting tools, to diagnose, identify and monitor data exceptions; Python experience is a plus.
- Understanding of data governance and data quality concepts (ownership, business definitions, data quality rules, lineage and metadata), with the ability to apply them with guidance.
- Strong analytical and problem-solving skills, with the ability to investigate breaks and discrepancies across multiple data sources and explain the findings clearly.
- Meticulous attention to detail and commitment to data quality and operational accuracy, with the ability to balance competing priorities and deliver results.
- Strong written and verbal communication skills, with the self-motivated ability to build relationships and influence stakeholders without direct authority.
- Bachelor’s degree in Business, Finance, MIS, Computer Science, or a related discipline.
Preferred:
- Exposure to AUM & Flows data, client wallet or Walletshare data, and asset management, wealth or institutional distribution data.
- High-level knowledge of asset management product offerings and their differences (models, funds, fund of fund structures).
- Experience working with third-party data vendors (e.g., SS&C Technologies, eVestment) and CRM platforms (e.g., Microsoft Dynamics).
- Financial services industry experience is a plus but not required.
