A Brief Overview

The US LBM Lead Software Engineer (Procure-to-Pay) will provide technical leadership while working hands-on alongside software engineers developing highly available applications, APIs, and integrations across US LBM's procure-to-pay platform, purchasing, invoice capture and matching, approvals, and accounts payable.
