We’re building the semantic backbone of WEX’s Data-as-a-Service (DaaS) platform—an extensible data layer that turns raw data into trusted, reusable, and business-aligned assets. As a Staff Software Engineer on the Semantic Data Modeling team, you will be at the forefront of designing and scaling the data foundation that supports analytics, AI, and operational decisions across all WEX domains. This isn’t a data wrangling or dashboard-building role. It’s a deeply technical, engineering-first position focused on building scalable systems that model complex business entities and relationships through high-performance, semantically meaningful data assets. WEX is re-architecting its data platform to enable domain ownership, semantic clarity, and enterprise-wide reuse. This role is critical to shaping that foundation—empowering teams to build once and use everywhere, from dashboards to machine learning pipelines. If you’re passionate about building systems that scale, and want to design the foundation that defines meaning in data, we’d love to hear from you.
