The job market is still about as hot as I've ever seen it as a senior engineer - I don't know what it looks like for juniors these days, but I know a lot of places are hiring a lot of people and some have been trying for over a year now to fill positions.
I think probably startups will take a hit, but there are plenty of places that pay well and do good things and need coders.
I'm just taking a guess, but wouldn't it make sense that more qualified people or people who have a good track record are going to have less trouble finding a job?
If 2009 is any gauge it comes gently and then suddenly. Ripple effects of contracting credit take a long time to work through the economy, so it's important to heed observations of the bow shock. Fewer startups, lower credit card limits, no access to cheap corporate debt, cost cutting, more conservative consumer spending, all add up until one day you're chatting to a recruiter who is visibly sweating as he tells you he hasn't placed a candidate in months.
I was already senior back in 2009 too and it was ugly. If your bum is not already in a seat, right now it should be your top priority, and you should absolutely be vetting the kinds of companies making you offers.
