Dive Brief:

• Zillow, Slack, Hubspot and Intuit have the top CEOs for women in technology to work for, as rated by women employees, a new study from Comparably found, using data from its database gleaned from April 2016 through April 2017. Zillow CEO Spencer Rascoff has a 98% approval rating, the highest among tech CEOs that made the list.
• But of the top CEOs on the list, none are women. Though women do hold executive positions, there are very few in CEO roles and are often rated lower than male counterparts, according to Comparably. 
• Unsurprisingly, the most popular tech jobs and highest median salaries for women are centralized in traditional tech hubs across the U.S., including San Francisco, Los Angeles, New York and Seattle, according to the report. But Austin, Boston, Chicago, Dallas and Washington D.C. are also emerging as tech hubs for women. Women in tech can earn the highest median annual salaries in San Francisco, where a VP of product can earn $190,000 and a VP of marketing can earn $180,000.

Dive Insight:

Though women hold leadership positions in tech, there is still a gap in what type of roles women hold. For example, Comparably noted the best cities and jobs for women in tech did not include C-suite roles, because there are not enough women in those roles to accurately compare salaries. Women are also more likely to be in marketing or product roles, rather than more technical development positions.

Women make up just one in five employees at the top 25 Silicon Valley firms, including companies such as Google, Hewlett Packard Enterprise, Apple and Intel, according to HiringSolved. Representation is a bit better among CIOs, with women comprising 19% of CIO positions across six major industries, Korn Ferry found. 

Tech is among the toughest glass ceilings for women to break. While advancements have been made in the sector, in some areas the number of women in the workforce has seen little growth. In security, for example, the number of women represented has remained stagnant since at least 2015.  

Contributing to the gender gap in tech are low offers and expectations for women working in the industry. But representation is also a big part of the issue. Last week at Apple's Worldwide Developers' Conference, women spoke just 7% of the time, though the company said it has made strides in promoting gender and ethnic diversity.
