What are possible careers that I could go into that combines language learning/traveling with a computer science degree?

Hi, Caroline! You have some really good interests.

A huge thing in the technology world right now is in connecting to the global community. A lot of tech companies, especially the ones that started in Silicon Valley in the past two decades, are founded by primarily English-speaking people, often Americans, and do not necessarily extend out to other parts of the world very effectively. If a company is founded and it makes an app that isn't translated to any other language, for example, then it will be a lot harder for people in other parts of the world to use it, even if they could benefit from it. This is to say nothing of the importance of understanding other countries and cultures in order to get a tool from simply usable to actually useful.

There are discussions by various companies of who the "next billion" users of the Internet will be, and a key feature is that they are in currently-developing parts of the world, often not speaking English. For an idea of some big companies that are interested in this, both Facebook's internet.org and Google's google.org (the "global impacts" sections in particular) are trying to figure out how to use Computer Science to help and connect to people all around the world, not just in English-speaking America and other so-called "first world" countries.

In short, the answer is basically "There are very beneficial jobs that involve traveling to other cultures where you can speak their language and then using your knowledge of CS to help."

I hope this helps! I can expand more if it isn't clear.

I work for a global company. We have major hubs on every continent (Ireland/Europe, Singapore/Asia, US/Americas), each serving the languages for the hub. At this company, a couple of roles that travel a lot and require language skills are process management and Sales/Sales Engineering. Starting in the U.S.: English, Spanish, and Portuguese (Brazil/rapidly growing tech country) are very helpful. If you want to head toward Asia: focus on English, Japanese, and Chinese. Also... India has a huge growing tech industry. Someone who speaks English, and multiple languages are in demand as they focus on source work for global corporations.

One area you might want to consider if you are looking to combine language and Computer Science is software localization. In the video game industry some games are developed in over 20 languages and there is specific software to help localize both the audio and the text. EA has a Madrid location and they often post for Localization Testers (a possible entry level, although these are usually native speakers) or Localization Engineers. Would suggest a quick google search for 'localization engineer' to give you a sense of the landscape.

Hi,
Great answers above from other people, I wanted to offer another suggestion...working for a company that does translation...computer programs, language translation software, etc...
Also, working for international agencies like the United Nations, US and other Governments and the military is a great way to travel, they have some of the best language training in the country at Defense Language Institute.

Good luck...you have a great, fun career and future in front of you if you learn multiple languages.
