Facebook Global Director of Diversity Maxine Williams is on a mission to make the social network a more inclusive place.

That’s not an easy task in Silicon Valley, an industry under fire for its relative lack of employee diversity. Many tech companies remain dominated by heterosexual white men, who earn thousands of dollars more per year than individuals from underrepresented groups, such as women, African Americans and the LGBTQ community. And just this week, a Google (GOOG, GOOGL) engineer circulated an internal memo around the company that criticized Google for its diversity efforts. Google ultimately fired the engineer, but the ensuing controversy was a stark reminder that tech companies have a long way to go to make their workplaces more inclusive.

Williams is acutely aware of the challenge at Facebook (FB), where progress so far has been promising, if slow. According to a diversity data report recently released by the social network, women now represent 35% of Facebook’s total workforce — up from 33% the year before — while representation for both Hispanic and African American employees increased just 1% year-over-year.

Williams has been trying to improve these numbers. Since joining the social network in September 2013, the Yale and Oxford-educated Trinidadian has introduced a slew of initiatives aimed at improving Facebook’s hiring and retention practices, particularly among underrepresented groups. In 2013, the company launched Facebook University, a two-month program aimed at training college freshmen from underrepresented communities in areas such as engineering and analytics. Some of the program’s 500-plus graduates have since gone on to intern or even work full-time at Facebook.

In 2015, the social network also rolled out the Diverse Slate Approach for hiring. The strategy, which is similar to the NFL’s Rooney Rule, requires Facebook hiring managers to at least consider underrepresented people for positions.

“What we wanted to do was to focus on giving more underrepresented people the opportunity to compete for these jobs,” Williams told Yahoo Finance in an interview in June, prior to the release of Facebook’s latest diversity data and the Google engineer’s now-infamous “anti-diversity” memo. That memo accused Google of “lowering the bar” for diversity candidates, something Williams suggests that Facebook does not do.

“We are not in the business of giving away jobs to anybody,” Williams added in the June interview. “That doesn’t serve us well. That doesn’t serve them well, but we saw again when you look at society and the hundreds of years of inequity, there are headwinds which have put some people at the front of the line. Then there are in some cases, deliberate policies and legislation keeping others back. If you’re working against that you have to be very intentional. What we wanted to be intentional around is giving everyone the opportunity to compete for the jobs.”
