Job Description

Title: Payment Developer (Java)

Location: EST Remote

Duration: Permanent role with client

Description

The client works with the world’s leading retailers to deliver segment defining, highly integrated, mobile solutions. The Concierge offering is a mission critical application that provides in-store team members with clientelling, assisted selling, mobile point of sale, and other key capabilities that deliver the future of retail. Concierge integrates existing retail investments including CRM, POS, eCommerce, Order Management, ERP, Payment, etc.

A big part of the solution is around mobile POS and taking legacy POS systems and transforming them into multi-threaded, web-based API services. This means ripping the UI off the system and reforming the non-thread-safe portions of the POS system. While these POS systems themselves are quite old, the technology we use to modernize them is not. We use Aspect Oriented Programming along with dependency injection frameworks and the Spark Java microservices framework to make the old, new.
