Master Data Management (MDM) & Entity Resolution Lead

Career Guide

A Master Data Management (MDM) & Entity Resolution Lead ensures an organization has reliable, consistent “core” data about key entities (such as customers, products, suppliers, locations, or employees). This role designs and runs the approach for matching and merging duplicate records, defining data standards, and helping teams trust shared data for reporting, operations, and customer experiences.

Key Responsibilities

Own the master data strategy for one or more domains (for example: Customer, Product, Supplier) and define what “good” looks like (accuracy, completeness, uniqueness, timeliness).
Lead entity resolution (record matching and de-duplication): set matching rules, manage exceptions, and continuously improve match quality.
Define and maintain data standards and governance: naming conventions, required fields, reference lists, and policies for creating/updating master records.
Partner with business and technical teams to map data flows across source systems, identify where duplicates/errors enter, and reduce them at the source.
Select, implement, or improve MDM and matching tools (including configuration, rule tuning, workflows, and integration with other systems).
Set up monitoring and reporting for data quality and match performance (for example: duplicate rate, match precision/recall, steward workload, time-to-resolution).
Manage data stewardship processes: triage queues, define decision rules, and coach stewards and analysts on how to handle exceptions.
Create and maintain documentation (data definitions, rulebooks, operating procedures) so processes are repeatable and auditable.
Coordinate cross-functional decisions when data conflicts arise (for example: which source system is “trusted” for a specific field).
Ensure compliance and appropriate handling of sensitive data (especially for customer and identity data), partnering with security/privacy teams as needed.

Top Skills for Success

Data quality management (profiling, rules, monitoring, issue management)

Entity resolution concepts (matching methods, survivorship rules, confidence scoring, exception handling)

SQL and data analysis (investigating anomalies, validating match results)

MDM platforms and tooling (configuration, workflows, integrations)

Data integration patterns (batch/stream, APIs, ETL/ELT)

Privacy and compliance basics for identity/customer data (consent, access controls, retention)

Common Skill Gaps

Often Missing Skills

Practical experience tuning matching rules and measuring match quality (not just “dedupe”)Understanding survivorship (which source wins) and how to manage data conflicts over timeDesigning stewardship workflows that actually scale (queues, SLAs, exception categories)Metrics literacy for entity resolution (precision/recall, false match vs missed match)Hands-on MDM tool configuration or integration experienceChange management: getting teams to adopt standards and fix issues upstream

Development SuggestionsBuild a small portfolio that demonstrates end-to-end entity resolution: profile a dataset, define match rules, measure outcomes, set up an exception workflow, and document governance decisions. Pair that with a real-world case study (even anonymized) showing how duplicate reduction improved a business outcome (reporting accuracy, customer experience, reduced mailings, fraud reduction).

Strengthen SQL and data investigation skills; practice explaining how you validated match results and handled edge cases.

Learn one leading MDM/matching platform (or an open approach) well enough to discuss configuration: matching rules, survivorship, workflow, and integrations.

Create a concise “MDM playbook” artifact: definitions, governance roles, matching strategy, stewardship workflow, and KPIs.

Prepare interview stories using metrics: duplicate rate reduction, match accuracy improvements, faster onboarding, fewer customer complaints, cleaner reporting.

Network with data governance and customer 360 leaders; many roles are filled through referrals due to cross-functional nature.

If you’re moving into a Lead role, demonstrate leadership: running working groups, making trade-offs, and driving adoption across teams.
