WEX OTR products enable credit issuance to fleet companies and their employees, and owner-operator truckers in the form of WEX Credit Cards, which can be used in fueling stations and select other merchants. At WEX, we provide fleet managers and operators with the ability to configure spend controls that restrict fleet members to use their card only at preconfigured merchants and for configured product families.

  • ​Establish a robust and clear engineering roadmap to maintain clarity and motivation for the engineering team. Maintain career growth plans and provide monthly and quarterly feedback for individuals’ continual progress.

  • ​Establish measurement of metrics-driven dev productivity across OTR APIs team.
