Data Scientist/Data Architect/Chief Data Officer and others are positions that are considered to be the most senior ones today.
If you’re working as a Data Scientist, your next job title may well be senior data scientist.
You might choose to specialize further in machine learning as a machine learning engineer, which would also bring a pay raise. Or, you can look more toward management with roles like lead data scientist. If you want to maximize earnings, your ultimate goal might be a C-suite role in data — such as chief data officer — although these roles require management skills and may not involve a lot of actual day-to-day work with data.
