Junior Java Developer; CHICAGO

Job Description

This developer will be working within the Loyalty space within Digital at a large global hotel chain. Currently there are tons of APIs all over the enterprise with different teams building them, and this hiring manager has initiated an effort to consolidate the APIs and bring them into a centralized area. The technical stack is Java, Spring boot, microservices/Kubernetes. This developer will develop Restful APIs and support technical issues as well, so they have to have the ability to go into systems (such as Data Dog) and troubleshoot why an API call failed.

Loyalty is integrated with every single system, so this person will research why an API is not working by looking at other teams’ code. They need to have an inquisitive, curious mindset to dive in, go down rabbit holes to track down root cause of issues.
