Computer and Information Analysts
Two of the computer analysis positions you can pursue with a computer science degree are information security analyst and computer systems analyst.
Computer systems analysts – or systems architects – study a business or organization’s computer systems, networks and protocols and try to find ways to make them work more efficiently. They work with clients to find and solve problems in databases and complaints from users. Most systems analysts specialize in computer systems common to a specific industry, such as financial computer systems, according to ComputerScience.org.
Computer systems analysts also:
- Combine technical and business knowledge to find ways to serve both goals
- Find ways to increase computer system capabilities and conduct cost/benefit analysis to help management evaluate investment in IT
- Research new technology and evaluate its potential benefit
- Manage installation of new system configurations and perform quality control testing
Many computer systems analysts have a bachelor’s degree in computer or information science, but a degree isn’t always required. Since they have to evaluate IT needs in the context of business goals properly, some system analysts take business courses or choose a business major with a computer science concentration, according to BLS.
Computer systems analysts made a median salary of $93,730 in 2020, and the field is expected to grow by 7% through 2029, according to BLS.
Information security analysts are charged with protecting a person or organization’s computer networks and data by monitoring those networks for cyber attacks and intrusions. Security analysts are often intimately involved in planning for a possible security breach and data recovery plan so companies can continue to operate if they are hacked.
Other duties include:
- Identifying and deploying software and firewall programs to protect against cyber attacks
- Documenting hacking attempts and security breaches
- Performing “penetration testing” by simulating attacks and highlighting weak points in a computer network
- Developing, recommending and updating an organization’s computer security protocols
Most information security analysts have at least a bachelor’s in a computer-related field, and many companies look for candidates with previous experience in a related field. Some companies prefer security analyst candidates with a Master of Business Administration in information systems, according to BLS. There are also many licensure opportunities for information security analysts, including the Certified Information Systems Security Professional designation.
Security analysts made a median salary of $103,590 in 2020, and the field is growing quickly. BLS estimates security analysts positions will grow 31% through 2029.
There are two main types of software developers, according to BLS:
Other typical core duties for software developers include:
- Analyzing user needs and developing, testing and creating applications and programs to meet those requirements
- Working with other specialists to develop software
- Identifying and recommending new software or software updates to meet clients' needs
- Executing a software maintenance and testing protocol to ensure software continues to operate optimally
Most software developers have a bachelor's degree and strong computer skills. In 2018, they earned a median income of $110,140, and the field is growing quickly and is estimated to grow by 22% through 2029, according to BLS.
Computer programmers learn and use programming languages such as Java and C++ and more to build to translate the designs of engineers and software developers into functioning computer code, according to ComputerScience.org. They write the specific instructions a machine follows to implement the designs created by software developers. They also test new applications and software programs and troubleshoot coding mistakes.
Computer programmers work hand in hand with software developers and engineers, and some of their job functions can overlap. Other duties for computer programmers include:
- Being fluent in multiple programming languages to write computer programs
- Updating and maintaining existing software programs and applications
- Testing programs for errors and fixing computer code to fix those errors
Most computer programmers have a bachelor's degree. Many certifications are available in specific programming languages and products. Some companies require their programmers to become certified in the programs that company uses. To advance within a company, some programmers develop business experience and become computer systems analysts, and some become software developers, according to BLS.
Computer programmers earned a median salary of $89,190 in 2020, according to BLS.
Web development is a subset of computer programming that focuses on "websites and applications," according to ComputerScience.org. Web developers specialize in creating the websites most of us use every day, from the aesthetics of the site to its technical capabilities and performance. Web developers also work on the content of a website and work with clients or a company's internal stakeholders to build the functionality the site needs.
While some web developers work on all aspects of a website, others have specialties, according to BLS, including:
- Front-End Developers create the look and feel of a website, including layout, integrating applications and other content.
- Back-End Developers work on the behind-the-scenes structure of websites that most users never see. They ensure the technical aspects of the programs that allow the site to function are working correctly.
