Object Technology Solutions, Inc (OTSI) has an immediate opening for an IBM MDM ARCHITECT (REMOTE). Major Responsibilities 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 Qualifications and Experience 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 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 CI/CD 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) Migration from on‑premises infrastructure to the cloud Adoption of containerization for deployment and scalability #J-18808-Ljbffr Premier Inn Hotels LLC (UAE)
