At least one of the following: professional software engineering experience, including full-time, part-time, contract, or substantial open-source work; a bachelor's degree in Engineering, Philosophy, Theology, Mathematics, or another logic-focused discipline; or a recognized programming certification, such as a language certification or completed coding bootcamp. We believe some of the best ML engineers reason like philosophers, engineers, and theologians: they define terms carefully, test assumptions, and follow an argument to its conclusion.
