About the Team/Role
You'll join a high-performing engineering team building our contemporary payments platform,
currently powering corporate payments with plans to expand across all lines of business.
You'll work on an event-driven, microservices architecture in Kubernetes, using Terraform,
Kafka, and CI/CD to enable true continuous delivery. You'll embrace AI-assisted engineering
to improve quality, speed, and your own developer experience.
As a senior engineer, you'll tackle complex technical problems, ship production code
regularly, and raise the bar for engineering quality across the team. You'll mentor others,
contribute to architectural decisions, and take ownership of features end-to-end. Your work
directly impacts WEX's ability to process payments reliably and securely at scale.

Who This Role Is For
This role is for engineers who want to do meaningful work on hard problems — not just
ticket-takers who wait to be told what to build.

We're looking for someone who:
● Takes ownership of problems, not just tasks
● Writes clean, testable code and cares about doing things properly




● Can work across the stack when needed, but has depth in backend systems
● Communicates clearly and collaborates well with product and other engineers
● Wants to keep learning and isn't precious about their own code

How You'll Make an Impact
Technical Delivery
● Design, build, and ship features end-to-end — from understanding requirements
through to production deployment and monitoring
● Write production-quality C#/.NET code with appropriate test coverage
● Build and maintain services that process payments reliably at scale
● Contribute to architectural discussions and technical decision-making
● Use AI-assisted development tools effectively to accelerate your work

Quality & Operations
● Own the quality of what you ship — write tests, monitor production, fix issues
● Participate in code reviews that improve the codebase and help others grow
● Reduce tech debt and improve developer experien
