CBRE, the largest real-estate service and brokerage firm in the world, employs more than 100,000 people.

The company helps its clients buy, sell, and manage real estate — and as a result, it hires a range of workers, from mechanics who make sure massive buildings can operate to brokers who facilitate and help fund some of real estate's largest deals.

2021 was a banner year for CBRE, which set an annual record of almost $28 billion in revenue as the rental-housing and industrial segments of the commercial-real-estate market became some of the strongest sectors in the economy.

While the is-it-or-isn't-it recession has some people questioning the health of the economy, CBRE is recruiting new talent at a breakneck pace, posting more than 250 US-based jobs just this past week.

Insider analyzed the US Office of Foreign Labor Certification's 2021 and 2022 disclosure data for permanent and temporary foreign workers to find out what CBRE paid US-based employees in entry-level to executive roles.

Most of the roles were professional jobs such as software engineers and business and financial analysts; the data did not include maintenance, operations, or sales staff. Performance bonuses or commission, signing bonuses, and compensation other than base salary were not reflected in the data.

CBRE hired 298 employees through the H1-B and related visa programs in 2021, a 119% increase from its total in 2020.

Here's how much CBRE pays, based on what it's offered foreign employees.

Once considered one of the least tech-savvy fields, the real-estate industry has invested heavily in technological development over the past few years. Tech hires made up the lion's share of CBRE's foreign-worker hiring in 2021 and the first quarter of 2022.

It's unclear from the data which departments within CBRE these workers ended up in. But they may be involved in the creation or maintenance of apps used by building managers and tenants, or in maintaining CBRE's massive data platform that powers much of its advisory and investment work.

Behind the scenes of every major transaction and business decision are the number crunchers and operations experts — they analyze the effect of each choice CBRE and its clients make.

A lot more goes into managing an office tower or apartment complex than turning on the light switch. These employees harness technical skills — from digital prowess to mechanical aptitude — to make sure buildings run efficiently.

CBRE not only manages properties and facilitates transactions but helps clients design and construct their buildings.

These workers manage tech and business products and important projects to make sure everything is done correctly and on time.

These employees sit atop the org chart, overseeing all aspects of CBRE's vast business. Unsurprisingly, they also have some of the largest salaries.
