How do I find out about jobs working on WCF?

That's an excellent question. I went to the Microsoft career site and I had a hell of a time finding the jobs that I knew we had available. I ended up finding them by reverse engineering the positions I knew were open until I got search queries that found those positions. In the end, I still couldn't find all the jobs, but I did get to a query that found a pretty good number. This query also has very few false positives, although there are a few jobs that have nothing to do with WCF or future products. You should hopefully be able to spot the fakes immediately upon reading the first paragraph of the job description.

Here's the query.

1. Go to the job search page: http://members.microsoft.com/careers/search/default.aspx.
2. Leave Job Title at "All".
3. Pick Location "WA - Redmond".
4. Pick Job Categories "Program Management", "Software Development", and "Software Testing".
5. What Product do you pick? Is Windows Communications the same as WCF? No. Is it part of the .NET Framework? No. All of the WCF jobs that I could find were filed as "(Not Product Specific)".
6. In the Keywords field put "wcf csd", either with or without the quotes should work.

That search should give you about 50 total jobs to look at.
