Express will not work. In fact, if you install SQL Server Express 2012 on a workstation, you WILL NOT be able to properly install SQL Server Data Tools, which are required to develop SSIS jobs!

Fortunately, you can get the developer edition for a modest price. It looks like DVDs for 2012 Developer are no longer available from Microsoft, but you can get the 2014 Developer Edition
