Experienced median pay: $136,000

High job satisfaction: 90% of employees

Salesforce is a demanding workplace — only 1% of employees reported having low-stress jobs to PayScale — but the company strives to create a happy work environment, earning the highest job-satisfaction mark on our ranking behind Facebook. The customer-relationship software company offers on-site fitness and massages, standing and treadmill desks, free snacks and drinks, and dog-friendly offices.

Employee participation in philanthropic work is important as well. Workers can take six days off a year to volunteer, and the company also coordinates volunteer trips around the world.
