Plug is a payments orchestration platform. Through one integration, merchants can have access to multiple connections to payments-related services such as credit card processing, alternative payment methods, banking, anti-fraud solutions, and more. Through our provider agnostic card vault and routing / retry engine, we are able to provide the best payments experience for the merchant ensuring they avoid lock-ins, while optimizing their cost and acceptance rate. 

We’re a well-funded startup backed by experienced and strategic angels from the tech and payments space. The team is currently comprised of senior professionals experienced in early and late-stage technology companies as well as in the payments space. 

We’re big on personal and professional development, and are looking for people who are as well! In addition, we look for people who can clearly articulate their ideas, but also be flexible to other points of view. If you like to collaborate, solve a real pain, and build products customers love, Plug is the right place for you.
