A systems developer performs a combination of the duties of a programmer and a systems administrator. He or she creates and tests Web-based and standalone computer applications, writes documentation for users, designs computer systems and maintains the programs and systems created. To become a systems developer, you'll need to be proficient in both the hardware and software aspects of computing, know about databases and how to use them with programs, and have a strong background in both desktop and Web-based programming languages. You also may need a college degree, vendor-specific information technology certifications and experience in programming or systems administration.
The knowledge required to become a systems developer varies because businesses vary on the systems developer's duties. Usually, you will need to be familiar with popular operating systems and may need to know how to write scripts to perform administrative duties more efficiently. Depending on the operating systems for which you'll write programs, you'll need to know how to package your software so users can install your software easily. Although knowing various programming languages and Web technologies can help you on the job, some employers may prefer one or two specific languages. In addition to writing and testing your programming code, you also will need to know how to implement your programs to work with other technologies, including databases and Web programming.
Some employers require a bachelor's degree as the bare minimum, but others sometimes accept a combination of work experience and vendor-specific certifications for you to become a systems developer. The most popular college majors for systems developers include computer science, information technology, software engineering and information systems. Regardless of your major, you should take a variety of courses that involve different programming languages, systems analysis, computer hardware, computer operating systems and database design. If you go for certifications, you should get a certification relevant to the programming languages or operating systems with which you are most familiar. There also are generic systems development certifications available that can help you become familiar with the basics of systems development.
If you plan to become a systems developer but lack work experience, you should plan on spending some time as an entry-level programmer or systems analyst. Many employers prefer three or more years of experience in programming and may require that you have gained that experience using specific programming languages. You'll probably find that an internship or freelance programming projects will help you gain the needed experience while you complete your degree.
