Find example companies, find their current or past jobs postings (maybe use the wayback machine), and identify the specific technology and techniques they request. Use that to write a map and plan.

Start using those technologies and building things. Write or at least post about it on X and follow related engineers on X. See kache's robotics journeyman community as one place for inspiration.

I just visit that journeyman community and looks like they are pretty stringent about that weekly update.
