We work hand in hand with the ML team here. It's one of those rare environments where the problems are genuinely hard (adversarial ML at scale is no joke) and the people solving them are both brilliant and low-ego. Happy to answer questions.
I am currently an EM who is still very hands-on. Though I have taken graduate-level courses in Machine Learning, Computer Vision, and Data Science, I have never worked on a production machine learning project. I would love to apply, but I'm not sure if I have what you are looking for.
