301 to related category of jobs or list of related job offers on the subject sounds like the best solution. At least, if I was searching for a job in a specific area then i'd be happy if other options were also provided .. But that's from a user-perspective, not from a SEO..Wait, didn't some of the SE's say that you should build sites for users and not for engines? Engines will catch up on what you're doing and adjust accordingly..
Sincerely, and have fun
