I went with "I was recently offered a position as a Data Scientist for another company, and unfortunately, it's an offer that I cannot decline." and then later on in the letter "Thank you for the opportunities that you have provided me during the last year and a half. I have truly enjoyed my tenure with company X, and am more than grateful for the encouragement you have given me in pursuing my professional and personal growth objectives." @anoplexian
- Just really highlight how much you have appreciated working for them
It's never easy to resign from a company that you really like and when they haven't done anything wrong
But as long as you're nice about it, they will understand it's just a professional decision and nothing personal
