Computer Science Career Options

  Computer science is one of the fastest growing industries in the United States. As computers continue to become more central to business functions, all organizations are implementing more sophisticated and complex technology, fueling a demand for computer scientists and database administrators. Computer scientists work as theorists, researchers, or inventors. Their higher level of theoretical expertise, innovation, and creation or application of new technology distinguishes the positions they acquire. Some researchers work on advancing uses of virtual reality, extending human-computer interaction, or designing robots, while others devote their research to proving theory. Computer scientists who occupy inventing positions focus on projects that have the possibility of producing patents and/or profits and work for industry leaders such as Microsoft, Google, Intel and Apple. Regardless of which area of computer science interests you, with a Computer Science degree from JHU, you have the unique opportunity to enter a variety of workforce areas such as software development; computer security; internet and e-commerce; aerospace; micro-surgery; biomedicine; bioinformatics; as well as R&D in both the private and public sectors.

Tim Train- President, Big Huge Games, THQ, International Studies major / Psychology minor, Class of 1991

  1. Describe what you do and how you got started in your current career. - I run a 130-person game development studio located in Hunt Valley, MD. I started as a play-tester right out of college, getting paid very little money for a lot of work with a local company. My first full project was the original Sid Meier’s Civilization; I went on to work on Civilization II, Alpha Centuari, and Civ III in various capacities. Although being a play-tester can be a difficult job, it’s a great introduction to the industry, and functions in a similar fashion to the “mail room” of a Hollywood studio in the good ol’ days—you find a lot of great talent there. Several JHU alumni followed me into the test lab.
  2. What is most rewarding about your job and/ or industry? What is most challenging? - I can’t imagine a better job in the world. I get to work with some of the most intelligent, funny, and creative people anywhere, all in the service to helping millions of people have more fun in their lives. The most challenging aspect is the time commitment. The games industry is part of the entertainment industry. Like music, movies, or television, working in this industry is a lifestyle choice as much as it is a job. Although things have gotten better since I joined the industry, where months of 80-hour workweeks were the norm, you still go through periods of crunch when you are trying to make a milestone or ship a game.
  3. Is your career the same or different from what you had envisioned your career would be when you started at Hopkins as an undergraduate? How is it similar and/or different? - I had no earthly idea that people even made videogames for a living. If I had that thought, I might have been much more focused in my undergraduate studies. I’d have taken more CS (even though I don’t deal much in tech).
  4. What advice do you have for a Hopkins student entering your career field / industry? - Pick something, and be great at it. There are four major disciplines in the game industry: art, design, programming, and production (project management). Pretty much any degree you might get could map onto one of those disciplines, so long as you excel at your chosen field. Take as many CS courses as you can stomach, whether that's one or a dozen. You don't have to have a technical background (unless you want to be a programmer), but every piece of tech knowledge helps you be a better game maker.

James Warner- Principal, Software Development, Structural Wealth Management Software Development, Computer Science, Applied Mathematics & Statistics, Class of 2001

  1. How did you get interested in your field? Was it your original goal when you started at Hopkins? - I became interested in Computer Science in high school, and intended to major in it when I came to JHU. I added the second major of Applied Math later.
  2. What was your career path? How did you get to where you are today? - I started as a software developer after college at a big company. After 6.5 years, I moved to a small company to head the development team.
  3. What was your first job after college? Was it in your current field? - I was a software developer at Oracle.
  4. What advice do you have for current students? - Being in a quantitative field will open doors in your career. Also, developing software is not only a job for people who don't like working with people.
  5. What is your typical day like? - I go to a lot of meetings and do a lot of planning for future projects. I also consult with more junior developers when problems arise. When I get a few hours to sit and write code, I find it very relaxing.
  6. What’s most rewarding about your industry and/ or job? What's most challenging? - I find building and mentoring a team of great developers to be very rewarding. I also love the feeling of launching a great new software project - it's very tangible and satisfying. The strategy part is very challenging.
  7. What are typical entry-level positions for this field? What tips do you have for students to be successful in these positions? - There are lots of entry level software development jobs. Just keep in mind that writing software professionally isn't like writing software in college. Be ready to learn.
  8. Where do you see the field going in the next 5-10 years? - The need for top-end development talent will continue to grow as technology becomes a bigger and bigger part of our economy.
  9. What skills and out-of-class experiences are ideal for entering your industry / career field? - Anything that gets you writing code in a more professional, formal environment is very valuable.
  10. Where can someone in an entry-level position expect to be in two years? Five years? Ten years? - There are a lot of different paths for a software developer - it depends what you're best at and what is right for you. You can become an architect, a manager, a product manager, etc.
  11. Which professional organizations and resources should students look into or get involved with? - I would really just recommend talking with people who write software for a living in a variety of settings and finding out what is right for you.
