What Computer Programmers Do

Computer programmers write code to create software programs. They turn the program designs created by software developers and engineers into instructions that a computer can follow. Programmers must debug the programs—that is, test them to ensure that they produce the expected results. If a program does not work correctly, they check the code for mistakes and fix them.

Duties

Computer programmers typically do the following:

  • Write programs in a variety of computer languages, such as C++ and Java
  • Update and expand existing programs
  • Debug programs by testing for and fixing errors
  • Build and use computer-assisted software engineering (CASE) tools to automate the writing of some code
  • Use code libraries, which are collections of independent lines of code, to simplify the writing

Programmers work closely with software developers, and in some businesses, their duties overlap. When this happens, programmers can do work that is typical of developers, such as designing the program. This entails initially planning the software, creating models and flowcharts detailing how the code is to be written, writing and debugging code, and designing an application or systems interface.

Some programs are relatively simple and usually take a few days to write, such as creating mobile applications for cell phones. Other programs, like computer operating systems, are more complex and can take a year or more to complete.

Software-as-a-service (SaaS), which consists of applications provided through the Internet, is a growing field. Although programmers typically need to rewrite their programs to work on different systems platforms such as Windows or OS X, applications created using SaaS work on all platforms. That is why programmers writing for software-as-a-service applications may not have to update as much code as other programmers and can instead spend more time writing new programs.

How to Become a Computer Programmer

Most computer programmers have a bachelor’s degree in computer science or a related subject; however, some employers hire workers with an associate’s degree. Most programmers specialize in a few programming languages.

Education

Most computer programmers have a bachelor’s degree; however, some employers hire workers who have an associate’s degree. Most programmers get a degree in computer science or a related subject. Programmers who work in specific fields, such as healthcare or accounting, may take classes in that field to supplement their degree in computer programming. In addition, employers value experience, which many students gain through internships.

Most programmers learn only a few computer languages while in school. However, a computer science degree gives students the skills needed to learn new computer languages easily. During their classes, students receive hands-on experience writing code, debugging programs, and doing many other tasks that they will perform on the job.

To keep up with changing technology, computer programmers may take continuing education and professional development seminars to learn new programming languages or about upgrades to programming languages they already know.

Licenses, Certifications, and Registrations

Programmers can become certified in specific programming languages or for vendor-specific programming products. Some companies may require their computer programmers to be certified in the products they use.

Other Experience

Many students gain experience in computer programming by completing an internship at a software company while in college.

Advancement

Programmers who have general business experience may become computer systems analysts. With experience, some programmers may become software developers. They may also be promoted to managerial positions. For more information, see the profiles on computer systems analysts, software developers, and computer and information systems managers.

Important Qualities

Analytical skills. Computer programmers must understand complex instructions in order to create computer code.

Concentration. Programmers must be able to work at a computer, writing lines of code for long periods of time.

Detail oriented. Computer programmers must closely examine the code they write because a small mistake can affect the entire computer program.

Troubleshooting skills. An important part of a programmer’s job is to check the code for errors and fix any they find.

Employment of computer programmers is projected to grow 8 percent from 2012 to 2022, about as fast as the average for all occupations. Computer programming can be done from anywhere in the world, so companies sometimes hire programmers in countries where wages are lower. This ongoing trend is projected to limit growth for computer programmers in the United States. However, some companies are bringing programming jobs back to the United States. In addition, companies with small information technology operations may outsource computer programming to low-cost areas within the United States.

Many computer programmers work in computer system design and related services, an industry which is expected to grow as a result of an increasing demand for new computer software. This includes software offered over the Internet, which should lower costs for firms and allow for more customization for users. In addition, new applications will have to be developed for mobile technology and the healthcare industry. An increase in computer systems that are built into electronics and other non-computer products should result in some job growth for computer programmers and software developers.

Job Prospects

Job prospects will be best for programmers who have a bachelor’s degree or higher and knowledge of a variety of programming languages. Keeping up to date with the newest programming tools will also improve job prospects.
