**** About the Team/Role
**** WEX is reimagining its enterprise data platform with a powerful goal: transforming raw data into semantically meaningful, reusable, and trusted business assets. As a
** Senior Software Engineer
** on the
** Semantic Data Modeling Team**, you’ll play a critical role in designing, building, and maintaining our core 360 data objects—such as Customer
360, Fleet
360, and Provider
360.These wide, entity-based tables are foundational to our analytics, AI, and product platforms. You’ll implement rich transformation logic, encode business rules, and ensure data consistency across domains—making our data models both technically scalable and business-ready.

This team is at the heart of WEX’s DaaS platform—bridging raw data with meaningful business insights. You’ll help define and deliver the
** semantic backbone
** of our products, analytics, and machine learning systems.

If you're excited about building data models that carry real-world meaning, scale to billions of records, and unify how a business understands its world—this is your next big move.
**** How you’ll make an impact
***** Design and implement
** semantically consistent, scalable 360 data models
** that integrate data across domains.
* Build and maintain transformation pipelines that apply
** cleansing, standardization, enrichment, and derived logic
** to domain datasets.
* Write production-quality, testable code in SQL and Python (or equivalent)—delivering performant and maintainable data assets.
* Work closely with domain experts, data scientists, and product stakeholders to translate business concepts into
** interpretable, decision-ready data models.
*** Implement logic for
** classifications, KPIs, scoring algorithms, and business rules**, ensuring traceability and data lineage.
* Help define and enforce standards for
** data modeling, documentation, and governance
** within the semantic layer.
* Collaborate across teams to integrate with ingestion, MDM, and data product layers.###
**** Experience you’ll bring****
* ** 4+ years
** of experience in data engineering or software engineering with a focus on data transformation, modeling, or analytics platforms.
* Strong proficiency in
** SQL
* * and at least one general-purpose language such as
** Python
* * or
** Scala**.
* Experience building and scaling
** wide, entity-based tables
** and modeling domain concepts (e.g., customer, fleet, provider) into durable data objects.
* Solid understanding of
** data quality practices**—including validation, enrichment, schema enforcement, and business rule encoding.
* Experience working with
** large-scale datasets
** and optimizing transformation pipelines for performance and maintainability.
* Comfort operating in a
** collaborative, cross-functional environment****,
** balancing business logic with platform scalability.
* A mindset for
** traceability, reproducibility, and semantic clarity**—you build data models others can trust and reuse.

Bachelor's degree in Computer Science, Software Engineering, or related field; A Master's or PhD in the areas of Data Science, Machine Learning, Artificial Intelligence, Computer Science, or Statistics, it will be a big plus.
