Choosing the Right Computer Science Specialization
A rewarding and well-paying job in computer science is attainable for individuals with an interest in any of the above computer science concentrations. However, mid-career professionals may be hesitant to transition into the field due to common misconceptions about computer science, including that it requires exceptional math skills, or that it means sitting in front of a computer screen all day and night.
It is true that some of the skills needed for a career in computer science are technical. The application development company, BHW Group, notes that reading code, evaluating frameworks, using debuggers, and practicing source control are important skills for anyone directly involved in the process of building software, for example.
However, many computer science jobs require skills beyond writing and evaluating code. According to O*Net Online, these roles also require creativity, critical thinking, problem-solving, project or proposal evaluation, and communication with software end-users, management, or leadership staff. Individuals in these positions must also be comfortable working with teams of various sizes, as much of their work is done in groups.
Ultimately, choosing the right computer science specialization comes down to your personal interests and professional goals. Consider some of the if/then scenarios below to see if your specific preferences align well with a particular career path:
- If you have an eye for visual design and keen attention to detail, then consider a role as a programmer, game designer, computer graphics designer, or UX designer. These roles also require creativity and flexibility for meeting the requirements of internal and external stakeholders.
- If you have a background in technical training and back-end operations, consider a role as an engineer, system administrator, or network administrator.
- If you have technical expertise as well as an ability to negotiate diplomatically, consider a role in information security. Another possible role is a DevOps—shorthand for “developer operations”—engineer, a role that helps organizations bridge the gap between speed and stability in the development lifecycle.
- If you like to analyze data, detect patterns and gain insights that lead to more informed business decisions, consider a career in artificial intelligence, data science, data analysis, or computer theory. Note that these roles also require presenting the outcome of data analysis to key stakeholders in clear language.
Due to the array of specializations within the computer science industry, it’s important to find a career path that aligns with your abilities, technical background, and long-term goals. The Master of Science in Computer Science curriculum at Northeastern is specifically designed to help you identify the computer science specialization that best matches your career interests, and to continue to develop the technical skills necessary to secure a fulfilling job within that specialization.
