EPAM’s Data AI & Analytics Team is seeking a Senior Python Developer (or Lead, depending on experience) to work on an exciting project for one of our major Financial Services clients.
In this role, you will partner closely with the client to scale and enhance a chatbot application designed to streamline daily workflows for financial professionals.
