What is the industry equivalent of a post doc? I've just finished my PhD in Genetics, and I am looking at moving into industry, as a scientist. 

"Senior Scientist" seems to be the closest match, because the salary is slightly higher than a junior post-doc.
I am not sure how much sense this question makes, given that no position in a research lab is really comparable to a postdoc position.

That being said, I have seen the term "research staff member", or just "researcher" or "scientist" being used a lot as an entry-level, permanent position in a research lab which requires a PhD. "Senior scientist" or "senior researcher" is typically a bit more advanced ("researchers" become "senior researchers" through regular career progression). However, concrete names of course vary between companies, so you should never assume much of anything about a position purely based on its name.

That's a very bad heuristic. Too many other factors influence salary for it to be of any worth for judging the level of a position.
