What Is Software Engineering?

Software engineering is a discipline that covers all aspects of software development, including designing, building, testing, distributing and maintaining software products. The field requires engineering principles, problem-solving abilities and programming language skills to design software that meets various user needs. 

What sets software engineering apart from other disciplines is the flexibility it demands. Teams should feel comfortable applying Agile and Waterfall methods — the former promoting a more fluid approach, the latter offering a more structured option. And while languages like C++Java and Python are common in software engineering, the discipline is constantly evolving to include new programming languages like F#, Clojure and Apache Groovy. Those who excel in software engineering know how to juggle complex projects, pivot between different work methods and keep up with the latest industry technologies and trends to provide the best digital experiences possible.

At the heart of this discipline are software engineers. These computer science professionals use their understanding of engineering principles, methods and languages to create, maintain and update computer software. The software engineering field is very broad, with engineers having various roles and areas of technical expertise.

Types of Software Engineering

All parts of the software development life cycle — budgeting, analysis, design, development, testing, integration, maintenance and retirement — are considered a part of software engineering. These tasks often fall into three separate buckets depending on the needs of the project: operational software engineering, transitional software engineering and software engineering maintenance.

Operational Software Engineering

Operational software engineering involves tasks related to how software interacts with a system, including tasks and decisions made on its budget, how it works for teams and customers, its functionality within the system and any risks it may pose.

Transitional Software Engineering

Transitional software engineering ​​involves tasks related to the software’s flexibility and scalability when it’s shifted out of its initial environment.

Software Engineering Maintenance

Software engineering maintenance covers tasks related to improving and debugging existing software to account for changes in environment, emerging technologies or vulnerabilities and bugs that may have been neglected during a previous development cycle. Eventually, maintenance is phased out and retirement is initiated.


Programming Languages

Software engineers use languages to program computers to execute certain tasks. These programming languages serve as the basis for how applications and websites appear visually and how they carry out tasks. Most languages involve complicated structures that take engineers years to learn. Below are a few of the most popular programming languages used today:


As of 2022, 98 percent of all websites use JavaScript. This language plays a major role in front-end development to assure that interactive web pages run smoothly and function correctly. In addition, it’s an extremely flexible language that offers a range of data structures and allows even beginners to pick up on it quickly.


Python is an open source, user-friendly language that shines when it comes to code reusability and readability. The language is used for a wide variety of software engineering projects that range from application development and database creation to building AI and machine learning systems.


HTML and CSS often form the backbones of websites. HTML distinguishes specific elements on a web page, such as headers, paragraphs and lists. CSS adds more detail to the style and layout of these elements, enabling colors, sidebars and other advanced options.


C++ is an object-oriented language that is suited for various purposes. The language shares much of the same syntax with its predecessor C and is preferred when teams need to build software and hardware applications at a fast pace.


SQL is a programming language that allows teams to communicate with and shape databases to their liking. Software engineers rely on SQL to find specific information, organize data into tables and make adjustments to the original database.

Types of Software Engineer Roles

Software engineers have unique skill sets that allow them to perform certain computer engineering tasks. It usually takes a whole team of different types of engineers to efficiently produce successful applications. Below are just a few of the most in-demand types of engineers.

Front-End Engineer

Front-end engineers specialize in the development of customer-facing products. These user interface (UI) engineers deal with everything from cross-browser compatibility and fixing bug issues to incorporating design elements that provide the smoothest user experience on applications and websites.

Back-End Engineer

Back-end engineers specialize in the logic, performance and coding of the application that users don’t see. These engineers focus heavily on the code that is able to execute every action you take when using an application. Back-end engineers rely on different databases, caches, programming languages and Application Programming Interfaces (APIs) to make sure the back-end is free of bugs and running smoothly.

Full Stack Engineer

Full stack engineers are highly sought after because they have the knowledge and skills to handle both front- and back-end engineering tasks. Not only can these engineers create clean, working code on the backend, they also can implement design elements that help to create the best possible user experience.

Security Engineer

Security engineers are becoming highly sought after because of their importance in maintaining the health of an entity’s cyber infrastructure during disruptions such as natural disasters or cyber attacks. Security engineers use varying forms of cybersecurity tools to make sure their databases, systems and infrastructure are always safe from harm. The need for security engineers will grow even larger as cyber threats grow larger and more advanced than ever before.

DevOps Engineer

DevOps is a portmanteau of the phrases “software (dev)elopment” and “information-technology (op)erations.” DevOps engineers are in high demand because they are familiar with the DevOps practices that help reduce the time it takes to take an application from inception to launch, without reducing the overall quality of the work. In other words, DevOps engineers are highly skilled at improving the efficiency of software development.


​Software Engineering Job Outlook

If you’re a software engineer or looking to become one, you’re in luck. Software engineers have one of the healthiest job outlooks of any occupation in the world. Software engineers will always be in demand as technology keeps evolving and innovation keeps growing at high rates. According to the U.S. Bureau of Labor Statistics (which makes no distinction between software engineers and software developers):

  • Software employment will grow by 25 percent from 2021 to 2031.
  • Hiring of software engineers specifically will grow at 26 percent from 2021 to 2031.
  • California, Texas, Washington, New York and Virginia have the highest employment levels of software engineers.

Some of the sectors with the most need for software engineers are transportation, retail, e-commerce, media/entertainment and finance. Additionally, emerging technologies, like AI and machine learning, have made it to the forefront of the most in-demand technologies engineers should know.
