Senior Data Modeller / Data Product Designer

Position Description:

CGI 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 payment schema relationships, which will be used to help build a Payments context layer across payment types

Your future duties and 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

Required qualifications to be successful in this role:

• 8+ years of experience in data modelling across operational and analytical platforms.
• 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.
NICE TO HAVE
• Payments domain knowledge.
• Awareness of ISO 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.

CGI is providing a reasonable estimate of the pay range for this role. The determination of this range includes factors such as skill set level, geographic market, experience and training, and licenses and certifications. Compensation decisions depend on the facts and circumstances of each case. A reasonable estimate of the current range is $70,.00–$,.00. This role is an existing vacancy.
