Massive expansion plans announced by Apple, which plans to add thousands of jobs in Texas, and Google, which will add thousands of jobs in New York, dominated engineering job news during the last quarter of 2018. Their announcements followed Amazon’s decision to select two cities for its own expansion—in Virginia and New York.

But, according to a scan of hiring and firing notices for the final quarter of 2018, those giant tech firms weren’t the only ones deciding that the best place to add jobs was anywhere but at their home bases. The trend demonstrates how tough it can be to recruit for certain engineering specialties in a tight job market, and also reflects a recognition that geographic diversity, along with other workforce diversities, can help companies to compete.
