Middleware Developer

The Middleware area at Xpand IT helps clients improve business processes from end to end by implementing software solutions that enable several applications/components of a distributed system to communicate and manage data in an efficient and scalable manner. By design, these solutions enable interoperability between applications that may run in different operating environments (operating system or cloud provider) and communicate by exchanging data based on industry standards (JSON, XML, etc).


As a Middleware Developer, you’ll be responsible for learning about enterprise system integration and the full cycle development and its challenges. You will develop quality middleware solutions, based on WSO2 technology, while actively providing insight into solving problems, applying typical integration standards and best practices.
