I think (i could be wrong though), that a lot of reverse engineering jobs in the commercial sector are advertised as "Software engineers" or "software security", rarely do they use the title "Reverse Engineer", focus on the job description that contains relevant keywords.
As for A community for RE, unfortunately I only know of /r/ReverseEngineering and a discord channel, they both smack of elitism (those who know something will make you jump through hoops rather than suggest a reading material, some other place to look for your answer, or antagonize you in different ways), that has been my experience with them so far.
