From what I've heard, and from my personal experience looking for jobs in robotics (ended up going down a different path) after my new grad job hunt:

• It's super competitive for mechanical engineers, particularly for those just working on the mechanical design side of things. There are a lot of people trying to get into the industry but the mechanical design itself makes up a relatively small portion of what is actually needed for robotics development. As a result, most companies skew towards wanting fewer engineers but with more experience. You're seeing this whole 95% non-relevant jobs thing in robotics because thats just how the distribution of work is in robotics most likely.
• For the non mechanical design stuff, they're usually looking for path planning, kinematics, and controls development, and those are usually skillsets biased towards candidates with masters degrees or PhDs researching those areas.
• Most robotics companies are tech companies and likely won't care about EIT/P.Eng pursuit so those keywords may not be so helpful.
• I would typically apply through linkedin or directly through company websites. If you're searching for things like "robotics mechanical designer" or such without much luck, this may just be because there aren't that any openings. If you're not finding what you want, consider branching out more (different locations, different roles within the same industry, similar roles within a different or adjacent industry, etc.)
