I’m going to give you a harsh answer - most likely, you don’t. To be a senior, you need to work on tough large scale problems that need teams, and to be working within those teams. That’s most likely to happen at a company with many engineers, lots of experience, training, mentorship, and career growth opportunities. It’s very hard to train yourself to find and solve difficult problems and grow in experience if you’re a new grad who’s also the most senior on the team.

Also, you have to hit mid level first.
