Dolby Careers in San Francisco, CA

Talk about having a sound business model. Dolby Laboratories is the market leader in developing sound processing and noise reduction systems for use in professional and consumer audio and video equipment. Though it does make some of its own products, Dolby mostly licenses its technology to other manufacturers. (Licensing accounts for more than 75% of revenue.) The firm has about 1,900 patents and more than 990 trademarks worldwide. In film, the Dolby Digital format has become the de facto audio standard; its systems equip movie screens around the globe. The company has expanded into digital audio compression. American engineer and physicist Ray Dolby and his family own the more than 40-year-old company.
