Computer Scientist working on complex Software Engineering and Systems

Software Engineering and the other "branches" of Computer Science - from Machine Learning to Cybersecurity, Computer Engineering to Human Computer Interaction - all offer high-growth career paths and fascinating academic areas of study. While related, Computer Science offers a broad “generalist” understanding of all interconnected aspects of modern computers, while Software Engineering (or Development) focuses on the design and implementation of large-scale, complex software systems - for example, a personalized recommendations algorithm.

Which pursuit is right for you, based on your unique goals, interests and long-term aspirations?

In this guide, we’ll get into more specifics about what each path entails to help you make an informed decision when planning your education path and career trajectory. Both pursuits require basic-to-intermediate programming (coding) skills, but beyond that, do you want to zero in on the immediate, practical skills (like programming algorithms) without needing the "why", or do you need to know "why" things work the way they do, zooming out to see the bigger picture of low- vs. high-abstraction programming languages and where to integrate machine learning? Do you want the long-term career mobility and versatility a broad Computer Science platform provides, or do you want to focus on building products and services as a Software Engineer or Developer?

What is Software Engineering?

Software engineering is the process of developing new software to solve problems, help individuals accomplish tasks, and deliver solutions to meet different needs across a range of industries. The main focus is on designing and implementing programs and using different programming languages to help make those solutions widely available to users across different platforms.

As a software engineer, you’ll work primarily with algorithms, programming, user's needs, and problem solving. Some software engineers use their skills to create mobile apps, software, and algorithms for businesses. Others create games and programs designed for consumers. You will likely work alongside computer engineers who maintain the systems and hardware that your software will run on.

How Does Computer Science Differ?

Computer science provides a broad, generalist understanding of all facets of computers, software, systems and how emerging technologies like AI/Machine Learning integrate into or augment existing frameworks and paradigms. The career applications are broader: you may choose to work on networks, improve cybersecurity, build databases, create machine learning algorithms, and run functional analysis of different systems.

Software engineering is more focused on the design of large-scale systems, digital products and services. Software engineers decide what user problem the software needs to solve, prioritize features and functionality, prototype and test in an iterative cycle of constant learning and improving. Computer science goes far beyond designing large-scale systems and CS graduates are equipped to work on emerging technologies across a range of industry applications. A master’s in computer science can enable students to pursue careers in growing fields such as robotics, automation, and infrastructure development. MCS@Rice alumni have gone on to work as data scientists, software engineers, business strategists, software security architects, and more.
