WEX Tech Stack

Global commerce platform for fleet, healthcare, travel, and corporate payments

Software Development Portland, Maine 5,001–10,000 employees Founded 1983 Public Company

WEX operates a multi-vertical payments ecosystem (fleet, healthcare, travel, corporate) across 5,001–10,000 employees, with engineering-heavy hiring (114 active roles) concentrated on CI/CD pipeline work, microservice architecture, and modernization projects. The tech stack spans React/Angular frontends, C# and Python backends, Kafka streaming, and a modern data layer (Snowflake, dbt, Great Expectations, Apache Airflow), while active adoption of Plaid and iOS/Android signals expansion into embedded fintech and mobile-first payment flows. Pain-point data shows sustained pressure on time-to-market and technical debt reduction — the CI/CD and microservice initiatives directly address these constraints.
