Function

We’re looking for an experienced Mendix Developer to join our client’s team and take ownership of the design, development and delivery of Mendix applications.

• Develop high-quality microflows and nanoflows, including appropriate error handling and logging

• Build reusable modules and apply appropriate Mendix Marketplace/App Store module governance

• Integrate Mendix applications with external systems using REST, OData and messaging technologies

• Design integrations within a microservices-oriented architecture, including API design, service decomposition and clear service boundaries

• Work with Git for source control and contribute within an Agile/Scrum delivery environment

• Independently take ownership of development cases from analysis through delivery

• SAP, CPI or other ERP integration experience
