Job Description

TDS Payments Technology team is looking for a Full-time Senior Data Modeller / Data Product Designer — Enterprise Payments 

Enterprise Payments is seeking a Senior Data Modeller / Data Product Designer to design end-to-end data structures across our Payments data ecosystem — from MongoDB-based transactional Operational Data Stores (ODS) through to Azure Databricks curated data products. 

This role is focused on schema design, data product design, and context-layer modelling. The successful candidate will help define how Payments data is represented, governed, reused, and consumed across operational and analytical platforms. 

The role is approximately 75% data modelling / data product design and 25% data engineering enablement, working closely with business analysts, data engineers, analytics teams, architects, and Payments partners. 

The ideal candidate can bridge semi-structured JSON/MongoDB modelling, Databricks/Delta schema design, and reusable domain-oriented data products. The team will provide training on ISO 20022 payment schema relationships, which will be used to help build a Payments context layer across payment types. 

Key Responsibilities 

• Design JSON schemas for MongoDB-based transactional ODS capabilities, aligned to business workflows, query patterns, and schema evolution needs. 

• Design corresponding Databricks/Delta table schemas for curated, reusable data products. 

• Define reusable Payments data products across individual payment types and combined cross-payment views. 

• Design a context layer / canonical Payments model that supports cross-product analytics, reporting, and downstream consumption. 

• Translate business requirements into logical and physical data models for both operational and analytical use cases. 

• Support schema evolution, versioning, migration, and backward compatibility across MongoDB and Databricks. 

• Design data products aligned to Unity Catalog structures, access patterns, discoverability, and governed sharing.  

• Differentiate between source-aligned, domain-aligned, and consumer-aligned data products.  

• Collaborate with data engineering teams to operationalize models through ingestion, curation, and transformation pipelines. 

• Support governance expectations including metadata, data quality, lineage, access controls, and appropriate documentation. 

• Work with business and technology partners to ensure data products are understandable, reusable, and fit for consumption. 

Qualifications & Skills

Must Have Skills:

• Strong experience designing JSON / semi-structured schemas, preferably for MongoDB or similar document databases. 

• Strong experience designing SQL / analytical schemas for data platforms, warehouses, or lakehouses. 

• Experience translating business workflows and query patterns into durable, scalable schema designs. 

• Experience with schema evolution, versioning, backward compatibility, and migration strategies. 

• Experience designing reusable datasets or data products for analytics, reporting, APIs, or downstream consumers. 

• Strong understanding of data product concepts, including usability, reuse, ownership, documentation, and consumer alignment.  

• Working knowledge of Databricks / Delta Lake schema design, including partitioning and performance considerations. 

• Familiarity with Unity Catalog or equivalent governed catalog / metadata structures. 

• Strong SQL skills. 

• Ability to work closely with BSAs, engineers, architects, and business stakeholders. 

• Excellent communication, documentation, analytical thinking, and problem-solving skills. 

Good To Have Skills:

• Payments domain knowledge. 

• Awareness of ISO 20022 Payments schemas and relationship structures. 

• Experience designing canonical data models or context layers across multiple source systems. 

• Experience with MongoDB indexing, sharding, performance tuning, or MongoDB Atlas. 

• Experience with PySpark, Spark SQL, Delta Lake optimization, and Databricks performance patterns. 

• Experience with Azure Databricks, Azure Data Factory, Azure Synapse, or similar cloud data services. 

• Experience with Kafka, event schemas, schema registry, or streaming data patterns. 

• Familiarity with data governance processes such as privacy impact assessments, data access controls, metadata standards, lineage, and regulated-environment audit expectations. 

• Experience with Collibra or similar catalog / data governance tooling.
