What is Software Engineering? What does a software developer do?


What is a Software Engineer?

Software engineers are the people who make the digital world work. They’re responsible for groundbreaking social media apps, like Twitter and Instagram, that are programming the future of autonomous transportation, robotics, and even that fantastic website you’re reading right now. In short, every time you interact with a website, app, or digital screen, you encounter the work of talented software engineers.

Software engineers are, in a nutshell, IT professionals who use their vast knowledge of engineering principles, methods, and languages ​​to create, maintain, and update software. The field of software engineering is very broad, with engineers having various roles and technical expertise. Not everything you see on your computer is just magic. It takes a team of highly dedicated engineers, using their varied skills to bring you the information, media or digital experience you want right away.

What sets software engineers apart from most other professions is their flexibility and agility. From switching between highly complex projects on a daily basis to keeping abreast of the latest technology and industry trends, software engineers need to stay nimble to deliver the best possible digital experiences.

Another trait most successful engineers possess is the ability to communicate effectively. Engineers need to work well in teams because projects today involve many different technologies, coding languages, and specialties. Most projects are compartmentalized where each engineer works on a certain aspect and then passes it on to the next engineer who continues the process. In this case, excellent communication skills are a must to ensure that the product is developed efficiently and works well for the user.

Types of engineers

As stated above, engineers have unique skill sets that enable 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 some of the most in-demand types of engineers.

Front End Engineer

Front-end engineers specialize in developing products for customers. These user interface (UI) engineers take care of everything from cross-browser compatibility and bug fixing to incorporating design elements that provide the smoothest user experience on apps. and websites.

Back end engineer

Back-end engineers specialize in application logic, performance, and coding that users don’t see. These engineers focus heavily on code that can perfectly perform every action you perform while using an application. Back-end engineers rely on different databases, caches, programming languages, and application programming interfaces (APIs) to ensure the back-end is bug-free and working properly.

Full Stack Engineer

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

Security engineer

Security engineers are increasingly in demand due to their importance in maintaining the health of an entity’s cyberinfrastructure during disruptions such as natural disasters or cyberattacks. Security engineers use different forms of cybersecurity tools to ensure that their databases, systems, and infrastructure are always safe from harm. The need for security engineers will increase further as cyber threats become larger and more advanced than ever.

DevOps Engineer

DevOps is a portmanteau of the terms “software (dev) development” and “information-technology (operations)”. DevOps engineers are in high demand because they know DevOps practices that reduce the time it takes to take an application from concept to launch, without reducing the overall quality of work. In other words, DevOps engineers are highly skilled in delivering the highest levels of efficiency for software development.

Programming languages

Software engineers use languages ​​to program computers to perform certain tasks. These programming languages ​​serve as the basis for the visual appearance of applications and websites and the way they perform tasks. Most languages ​​involve complex structures that take engineers years to learn. Here are some of the most popular programming languages ​​in use today:


In 2019, it was reported that 95% of all websites used JavaScript. This language plays a major role in front-end development to ensure that interactive web pages work and function smoothly. Moreover, it is an extremely flexible language that allows even beginners to get used to it quickly.


Python is a user-friendly open-source language that shines in terms of code reuse and readability. The language is used for a wide variety of software engineering projects ranging from developing applications and creating databases to building AI and machine learning systems.

C is one of the original programming languages. Developed in 1971, C is still highly regarded for its ease of use when building high performance applications. It is mainly used today in booming technological fields, such as virtual reality, computer graphics and games.


Golang (or Go, for short) is an increasingly popular programming language that has a similar syntax (rules for structured symbols) to C, but with improved memory safety, readability, and high-performance multiprocessing. This general-purpose language, developed by Google, is used by companies like Uber, Docker, and Medium to build fast and flexible apps.
