BOSTON (CBS) – As Boston competes to land Amazon’s second headquarters and tens of thousands of new jobs, the tech giant has announced a more modest expansion in the city.

Amazon announced Tuesday that it is moving into a 430,000 square-foot office in the Seaport with plans to open in 2021. The company says that will lead to 2,000 new jobs, doubling its tech workforce in the Boston area.

“Massachusetts’ innovation economy is powered by a talented workforce, exceptional educational institutions and companies like Amazon at the forefront of research and development,” Gov. Charlie Baker said in a statement. “Amazon’s expansion in the Seaport will bring thousands of new jobs to the Commonwealth and build upon the hundreds of jobs they already have here in research and development, fulfillment centers and robotics.”

The Boston area is still in the running to land Amazon’s second headquarters. Amazon promises to invest $5 billion and create 50,000 high-paying jobs at “HQ2.”
