LONDON — Facebook said it plans to hire 10,000 workers in the European Union over the next five years to work on a new computing platform that promises to connect people virtually but could raise concerns about privacy and the social platform gaining more control over people’s online lives.

The company said in a blog post Sunday that those high-skilled workers will help build “the metaverse,” a futuristic notion for connecting online that uses augmented and virtual reality.

Facebook executives have been touting the metaverse as the next big thing after the mobile internet, though their track record is spotty on predicting future trends. Expectations that CEO Mark Zuckerberg made four years ago of taking virtual vacations with faraway loved ones via a headset or using a smartphone camera to improve an apartment virtually have not materialized so far.

The company also is contending with antitrust crackdowns, the testimony of whistleblowing former employees and concerns about how it handles vaccine-related and political misinformation.

“As we begin the journey of bringing the metaverse to life, the need for highly specialized engineers is one of Facebook’s most pressing priorities,” according to the blog post from Nick Clegg, vice president of global affairs, and Javier Olivan, vice president of central products.
