Software Development Engineer 1

About the Team & Role Team builds the infrastructure that keeps commercial drivers and fleets moving from fuel payments at the pump to the apps and backend services that power authorizations, loyalty, and real-time transaction data. As an SDE I, you'll join one of two full-stack engineering teams within WEX's Mobility organization.

Both teams own their systems end to end. The 10-4 (OTR) team builds the over-the-road platform customer-facing APIs, event-driven microservices (Java/Spring Boot, Python), Kafka-based async processing, payment and identity integrations (Fiserv, Okta), and the Android and iOS apps that drivers use in the field. The NA Mobility Platform team builds and owns the shared frontend infrastructure that product teams across the organization depend on Angular micro-frontends with NestJS BFFs, Module Federation, a shared component library (Theseus UI), brand theming, and app scaffolding via Theseus Builder. In both cases, you'll work across layers of a real production stack, ship to real users, and be supported by engineers who care about doing the work well. We value clean APIs, strong testing habits, and engineers who improve the systems they touch. You'll work closely with the product, other OTR teams, and your peers on features from design through implementation, testing, deployment, and production support.
