How to transition from staff eng to MLE?

Thank you! This is a gold mine, please let Ilya create a full course: https://www.jointaro.com/question/YqrpDDCPbsGpg0lwrKXY/looking-to-transition-to-ml-engineer-what-do-you-want-to-know/

he actually had one about design interview for MLE, but I think there is enough ground for non-interview topics https://www.jointaro.com/course/ace-the-machine-learning-system-design-interview/

Ilya is great about junior or mid level transition topics, or engineer career transition to MLE. However, I am more curious about staff+ and senior staff+ type of scope, work and expectations in my question
