Placing the code in Guthub or Google Code will make it much easier to validate that it is truly open source and will allow the next developer on the project to download the latest updates.

Also it might happen that while integrating it, improvements to the open source code come to mind. Then it should be clear from the start if it would be OK to feed improvements created during employed time back into the open source project.
You will also need to be careful about contributions back to your open source stuff. This is one of the areas that open source foundations have done really well. The dojo and Apache foundations as an example have you fill out a contributors agreement to ensure the IP of any code that is submitted to them is "clean".
