SENIOR PYTHON DEVELOPER

Python, reporting- part of the Enterprise Data Management team supporting treasury data

Want someone really good at python and sql and ok at power bi- just able to identify problems, not a report developer

Data processing and reporting overlap- the india team is responsible for that mostly, but this person would be responsible for responding to questions on reporting after india team logs off. IE- hey this number on my report is off, being able to go into the report and say ok this is whats pulling

The person who left- really willing to learn, invested time in understanding EDM app

Really need someone with core python and scripting- that's what they will be doing
