Amazon.com may allow dogs in the office and offer bus passes to staffers, but it is still among the most stressful big companies to work at in high-tech. And don’t let Mark Zuckerberg’s casual hoodie fool you. Facebook too was among the most stressful high-tech workplaces, though employees of the social networking powerhouse reported being the most satisfied in their jobs.

Those are some of the findings today from Payscale’s Technology Company Salary and Job Satisfaction Report. The survey by the Seattle company ranked nine technology companies on factors such as compensation, demographics and workplace flexibility.

The stresses at Amazon.com are well known. And while Payscale’s report points to some Amazon.com perks (bus passes, dogs in the office, restricted stock), it also shows some areas where it lags other high-tech employers. For example, employees at Amazon.com received a median of 2.2 weeks of vacation each year. Only Apple offered its workers less vacation time at 2.1 weeks.

Amazon.com also was ranked as the least flexible work environment of the nine tech companies surveyed. Microsoft, on the other hand, offers its employees the most flexibility.

Google and Microsoft offered the best pay. The median pay for mid-career workers at Google was $141,000. That compared to $110,000 at Amazon.com and $127,000 at Microsoft.

But Microsoft beat its search rival in terms of starting pay. The starting median pay at Microsoft was $86,900 — the best among the nine companies surveyed.

H-P paid the worst, with the report indicating that workers at the computer maker earn 15 percent less than similar workers at other big tech companies. H-P workers also were the least satisfied.

The tech business remains largely male dominated. A third of workers at Facebook are women, the best among the nine tech companies surveyed. Microsoft and Intel were at the bottom of the pack at 20 percent.

The report also listed some of the perks associated with each company, from health club memberships at Microsoft to free food at Google to free cable TV at H-P.

Here’s a look at the chart showing the top and bottom companies in terms of pay:
