Job description
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.
How You'll Make an Impact
- Build specific components within an established architecture. You'll follow the patterns your team
- has set, whether that's microservices, event-driven design, or component-based frontend, and
- implement features correctly within those structures rather than redefining them.
