Senior Software Engineer - Semantic Data Lake

About the team / Role
Senior Software Engineer, Semantic Data Team

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 Team, you'll contribute to designing, building, and maintaining control plane for Semantic layer and AI Native data platforms supporting our core 360 data objects (Customer, Fleet, Health and Payments)

An embedded DataOps backbone and self-service control plane ensures governance, lineage, observability, and operational efficiency at scale. Together, these elements empower WEX to modernize responsibly—continuously delivering business value while evolving toward a future where intelligence and automation are built on a foundation of governed, high-quality data.

This team is at the heart of WEX's DaaS platform where the platform integrates DataOps automation, control plane services, and governance tooling to uphold quality and trust at scale, enabling trusted, production-grade semantic models through automated controls, audit validation, and operational alignment.

Wex is highly invested in building AI native data platform. The Agentic Control Plane is the runtime layer that determines how an AI agent interprets a user request, assembles the right context, applies the right rules and constraints, uses approved tools, and drives the next step.

We're looking for an AI-native engineer: someone who builds with modern AI coding tools (Claude, Copilot, Cursor, and similar) and Spec-Driven Development (SDD) as a core part of their daily workflow. You'll use these tools to accelerate development and apply solid engineering judgment to ship production-grade, trustworthy data assets.

How you'll make an impact

• Engineer the Operational Backbone: You will design and implement the core infrastructure of the Control Plane, serving as the central execution engine that orchestrates the entire data lifecycle—from ingestion and transformation to final distribution.

• Shift from Reactive to Proactive: You will transform platform reliability by building sophisticated observability frameworks and automated quality gates, ensuring that data trust is engineered into the system rather than inspected after the fact.

• Drive Self-Service Autonomy: You will eliminate operational bottlenecks by developing intuitive portals and "golden templates," empowering domain teams to autonomously build, manage, and consume trusted data products.

• Champion Platform Governance: You will automate critical compliance and security policies, including end-to-end data lineage, role-based access control (RBAC), and PII protection, making security an inherent feature of our data objects.
