About the Role
WEX is transforming its enterprise data platform to create semantically meaningful, reusable, and trusted business assets. As a Senior Software Engineer on the Semantic Data Lake Team, you will design, build, and maintain core 360 data objects like Customer360, Fleet360, and Provider360. These entity-based tables are crucial for analytics, AI, and product platforms. You will implement transformation logic, encode business rules, and ensure data consistency, making data models scalable and business-ready. This role is central to WEX's DaaS platform, bridging raw data with business insights and defining the semantic backbone for products, analytics, and machine learning systems. We seek an AI-native engineer who uses modern AI coding tools (Claude, Copilot, Cursor) daily to accelerate design, generate/refactor logic, write tests, document semantics, and explore data, applying engineering judgment for production-grade data assets. This is an opportunity to build semantic models that scale to billions of records and unify business understanding with modern AI tooling.
Responsibilities
- 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.
- Leverage AI coding assistants (Claude, Copilot, Cursor, and similar) to accelerate development, critically reviewing AI output for correctness, performance, and alignment with business rules.
- Partner closely with the data products team to understand business requirements and ensure semantic models align with their needs.
- Implement logic for classifications, KPIs, scoring algorithms, and business rules, ensuring traceability and data lineage.
- Collaborate across teams to integrate with ingestion, MDM, and data product layers.
- Explore opportunities to expose 360 objects to LLM-powered and agentic applications.
Requirements
- 4-8 years of experience in data engineering or software engineering with a focus on data transformation, modeling, or analytics platforms.
- Strong proficiency in SQL.
- Strong proficiency in at least one general-purpose language such as Python or Scala.
- Demonstrated experience as an AI-native engineer using tools like Claude, GitHub Copilot, or Cursor as part of everyday development workflow.
- Comfort with modern AI engineering practices such as prompt design, context engineering, AI-assisted code review, and integrating LLMs or AI agents into engineering or data workflows.
- 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 in data models.
