Benefits of working at OpenDNS

  • Innovative -- We aren't a social networking or Web 2.0 photosharing site. We work on core Internet protocols and make them better.
  • No ladders to climb -- We keep a relatively flat corporate structure that promotes fast movement and flexible teams.
  • Meritocracy -- The best ideas win, regardless of where they come from.
  • Time off to relax -- As a startup, we work our butts off. That's why it's important to get away to clear your mind from time to time. Three weeks and 10 company holidays make that easy.
  • Technologists -- We are a company of engineers and technologists passionate about delivering a better Internet.
  • Offsites -- It takes getting away for a day every quarter to focus on where we want to be as a company and how we're going to get there.
  • No timecards -- We have a few weekly team meetings, but other than that delivering results counts for a lot more than sitting in your chair.
  • Food -- Hard work makes you hungry. We keep a well-stocked kitchen with everything from cereal to ice cream.
  • Frosty beverages -- Fridays often end with some nice frosty brewed beverages and good conversations.
  • Breakfast by the Founder/CEO -- The early bird gets the worm, or in our case waffles on most Wednesdays, served by our Founder/CEO.
  • Insurance -- We've got you covered from your head to your toes. Medical, Dental and Vision.
  • 401(k) -- We're set up to help our team members practice responsible fiscal management.
