Software engineering is a computer science field that is associated with software development. It entails the implementation of principles, procedures, and techniques in the development of software products that turn out ot be reliable and of high quality. In other words, software engineering is the process of applying engineering principles in the designing, development, testing, and maintenance of software products. And one who does this is a software engineer.
Often the terms software engineer and software developer are used interchangeably. However, both terms are different and have different duties to perform though they are involved in the software development process. While software engineers involve in the entire software development life cycle, software developers are only responsible for the development part of SDLC.
The role of software engineers in an organization is wide. In this blog, we shall thoroughly discuss what does a software engineer do. Before we get into the details, let's define what a software engineer is.
So, let us get started!
Who is a Software Engineer?
A software engineer is a specialist who uses their understanding of programming languages and software engineering principles to develop reliable software products. Alternatively, software engineers are professionals who design and develop application software and system software by implementing computer science principles and mathematical analysis.
Application software is a software program for accomplishing a specific task. Meanwhile, a system software is a computer program that manages system resources and provides a path for application software to operate on that system. It acts as a bridge between the system and the application software.
Generally, software engineers are problem-solvers, analytical thinkers, and strategically minded. They supervise the entire software development process, right from requirements analysis to deployment and maintenance. As a result, software engineers possess sound knowledge of software development, programming languages, operating systems, and software engineering principles.
Types of Software Engineers
There are two types of software engineers: Application software engineers and System software engineers.
Application Software Engineers
An application software engineer is an individual who is in charge of comprehending and analyzing end users’ requirements and building software products for businesses or organizations.
System Software Engineers
A system software engineer is a person who is responsible for the creation and maintenance of an organization or business’s computer systems. In addition, they are in charge of coordinating with the needs of all the departments of an organization, providing technical support, and setting up and managing the network that connects all the computer systems.
What Does a Software Engineer Do?
Typically, while developing software products, software engineers first choose the appropriate programming languages, platforms, and architectures. From basic computer games and programs to operating systems and network control systems, they are capable of doing it all. In addition to designing and creating software products, their duties also include testing, improving, and maintaining those created by other engineers.
The role of software engineers is broad, and hence, they need to possess an array of skills. Also, they have to stay up with the latest technological trends.
Here are some of the basic duties of a software engineer in every organization:
- Designing and maintaining software systems.
- Assessing or testing new software systems.
- Improving software products for speed and performance.
- Writing and testing code.
- Collaborating with clients, stakeholders, security specialists, and other engineers.
- Proposing new features to clients and stakeholders.
As discussed above, there are two categories of software engineers: Application software engineers and System software engineers. As a result, each sort of software developer has different duties and obligations. However, both categories continue to share the aforementioned duties.
Now, let's shed light on each type of software engineer's duties or everyday tasks.
Application Software Engineers
These software engineers prioritize the needs of the customers. They assess and comprehend the client's needs, then deliver the software program in accordance with those needs. They participate in the development of an application's client-side (front-end) and server-side (back-end). The duties of application software engineers are as follows:
- Creating software applications for Android, iOS, Windows, and other platforms.
- Analyzing the software requirements
- Modifying the software product in accordance with the client’s requirements.
- Releasing software updates regularly.
Who They Work With?
Application software engineers work with project managers, graphics designers, customer success staff, and marketers.
System Software Engineers
These software engineers are in charge of developing systems on which the front-end or user-facing applications will operate. They involve themselves mostly in the back-end development. Some of the significant everyday tasks of system software engineers include:
- Developing networks and operating systems for user-facing applications.
- Making sure that all software applications communicate with each other on a single platform.
- Establishing and enforcing IT standards within an organization.
- Keeping up with the latest technology.
- The maintenance of documents pertaining to IT systems.
- Serving as system architects and general IT managers.
- In charge of both hardware and software requirements.
Who They Work With?
System software engineers generally collaborate with data science professionals, senior system architects, senior management, and the development team.
Why Should You Choose to Become a Software Engineer?
The job role of a software engineer is for someone who possesses strong analytical skills, enjoys problem-solving, and is open to learning new technology. Also, you must be knowledgeable in a variety of areas, such as software engineering, programming languages, and software development, in order to be a successful software engineer.
