Highly recommend to avoid any companies that would touch ros with a 10ft pole. It's an unmitigated pile of endless shit, and any projects that don't recognize this are also.
But, the moment you ship your first product, open your task tracker and add “Epic: Migrate off of ROS to a custom framework”.

When robotics moves from the lab to the field, expensive certainty becomes more attractive than cheap flexibility.
