If you invented it, then they have to put your name on the application as the inventor. There’s also a declaration that the inventor is supposed to sign as part of the application. If the inventor is dead or otherwise unavailable (e.g., refuses to sign), there’s an alternative form that can be filed.
The inventive step is the actual decision of 'we will do this thing in this way', or rather determining the 'method'. In fact, the guidelines we follow are that someone implementing the design based on some instructions, i.e, just working on a ticket, is explicitly not to be included as an inventor - unless they actually decided that's how it should be done.
Of course, it's nice to work in a place whereby you get to design and implement the system and become an inventor. In my opinion and experience at least. But I can see some organisations whereby developers are popping off tickets in sprints and implementing them - but that is by definition not an inventive step.
"Having N patents" should be something that gets frowned on, not something you highlight on your resume. When asked about this myself (during interviews or whatever), I proudly boast that I have zero patents to my name and that I actively avoid being part of the problem by participating. I see it as an opportunity to 1. help steer our culture in whatever tiny way I can and 2. get up on a little soap box about the problem.
In the past, I've been asked to help out with patent applications for these so-called "inventions" that I developed, and I always tell my manager "If you want to patent this, I can't stop you, but do not put my name on it or associate it with me in any way."
