Project description

We are developing a high-performance workflow system for the client's onboarding domain. This system focuses on capturing various types of data from clients based on JSON schema. The project involves extending the workflow system functionalities, including a single-page application (SPA) written in React 17+ and a business-oriented components library that is reused by multiple applications to capture data. The UI team and most of the project team is co-located in Krakow - it means effective and close collaboration. We are looking for a proactive individual who can suggest improvements to the library and the application and take ownership of their work.
This person will collaborate with the business team and backend developers to discuss domain-level changes and will not shy away from participating in discussions.
