storing model in the session, is there a better way?

I am building an app where a user may have multiple Jobs (although most will have only one). When a user does have multiple they are asked to select which one they want to look at post login. At this point the site (navigation etc)is purely dependant on the selected job with the exception of a drop down in the nav to switch jobs.

Currently i store the results of the job in the session and refer to the session version of the job throughout the code. I feel like this isn't the best approach. What's the best way of remembering which job is "active". Id like to avoid coding it into the url.
