IBM MDM ARCHITECT

This is a remote position.

Object Technology Solutions, Inc (OTSI) has an immediate opening for an IBM MDM ARCHITECT

IBM MDM ARCHITECT (REMOTE )

MAJOR RESPONSIBILITES:

· Own data quality, matching logic, and golden record creation

· Strong experience in Master Data Management (MDM)

· Hands-on with:

· Matching & deduplication strategies

· Golden record creation

· Experience tuning:

· False positives / false negatives

· Knowledge of:

· Phonetic matching (Soundex, etc.)

· Data quality rules

· Key Responsibilities

· Define and tune matching algorithms

· Identify and fix:

· Duplicate records

· Data inconsistencies

· Work with business teams to:

· Define matching rules

· Handle edge cases

· Validate new data sources and ingestion logic

· Define data quality metrics & SLAs

· Good to Have

· Experience with tools like:

· Informatica MDM / Reltio / IBM MDM

· Exposure to SQL

· The right fit is looking for IBM MDM (virtual) guy who is able to move on-prem MDM to cloud with kubernetes and they would need Java knowledge

· Conduct comprehensive reviews of the current MDM ecosystem, including matching and linking algorithm performance, duplicate and suspect processing, and custom extensions.

· Evaluate and enhance logging, monitoring, backup, and recovery processes to ensure system reliability and resiliency.

· Assess and optimize transaction/query SLAs and index performance, identifying and addressing known issues such as bucket overflows and bulk-load mechanism gaps (including DataStage constraints).

· Design, develop, and maintain Java code for MDM algorithms, data processing, and integration components, ensuring code is performant, scalable, and maintainable.

· Refactor and optimize existing Java code, and write unit, integration, and system tests for all Java components.

· Adjust matching algorithm thresholds to minimize false positives/negatives and add/test new matching attributes (e.g., email + last name, phone combinations).

· Assess and implement phonetic matching techniques (e.g., Soundex), and lead feasibility studies to determine the need for single or multi-algorithm approaches for different business lines.

· Perform sample pairing for new data sources, collaborating with business teams to identify edge cases and refine algorithm behavior, including store-identifier-based auto-matching where applicable.

· Review and enhance frequency-based and dynamic bucketing strategies, assess passive execution options to minimize production impact, and validate interactions with STR tables and existing buckets.

· Develop and document bulk load strategies, including ingestion options with and without entity management/event handlers; explore disabling matching for high-volume ingestion scenarios (e.g., 200M+ records) and evaluate alternative ingestion patterns beyond API-only approaches.

· Capture and report on metrics, SLAs, and trade-offs for each ingestion strategy.

· Target

· Address deployment challenges such as outages and unpredictable environment behaviors; explore and implement CICD or improved deployment automation; review and optimize configuration, code, and deployment steps for efficiency.

· Plan and implement Auth/PingFed-based authentication, reduce reliance on process IDs and passwords, automate credential rotation, and maintain a dedicated 'Security' category in the scope documentation.

· Ensure all code adheres to coding standards and guidelines.

SKILLS AND ABILITIES REQUIRED

· Java 21 (core and advanced), including object-oriented programming and multithreading

· Master Data Management (MDM) platforms and tools

· Algorithm development for data matching, linking, and deduplication (including phonetic algorithms like Soundex)

· Data integration frameworks and ETL tools (e.g., DataStage)

· SQL and database optimization (indexing, query tuning, bulk operations)

· Performance tuning and system health monitoring for large-scale data systems

· Logging, monitoring, backup, and recovery solutions

· Load testing tools (e.g.,JMeter)

· CI/CD pipeline tools and deployment automation (e.g., Jenkins, GitHub)

· Secure coding practices, including Auth authentication and credential management

· Micro services API development and integration (e.g., RESTful services)

· Unit, integration, and system testing frameworks (e.g., JUnit, Mockito)

· Documentation tools (Confluence, GitHub, DX Guides)

· MDM Modernization

· Migration from on-premises infrastructure to the cloud

· Adoption of containerization for deployment and scalability
