• Digital Transformation (Cloud Computing, Mobility, Micro Services, RPA, Dev Ops)
• Enterprise Applications (SAP, Java Full stack, Microsoft, Custom Development)

This is a remote position.

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

• Own data quality, matching logic, and golden record creation
• Strong experience in Master Data Management (MDM)
• Hands‑on with matching & deduplication strategies
• Experience tuning matching algorithms and data quality rules
• Knowledge of phonetic matching (Soundex, etc.) and data quality rules
• Define and tune matching algorithms
• Identify and fix issues; work with business teams to define matching rules
• Handle edge cases; validate new data sources and ingestion logic
• Experience with tools like SQL, and exposure to SQL

• The right fit is looking for IBM MDM (virtual) specialist who can move on‑prem MDM to cloud with Kubernetes and has 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 Data Stage 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 < 2 seconds for matching response time through iterative tuning, must‑gather data analysis, and leveraging load testing tools (e.g., JMeter); review reconciliation SLAs as part of ongoing optimization.
• Address deployment challenges such as outages and unpredictable environment behaviors; explore and implement CI/CD or improved deployment automation; review and optimize configuration, code, and deployment steps for…
