Software engineers develop innovative ways to use available technology, continuously improving upon the efficiency and functionality of programs. If you are planning a career in software engineering, it is important to understand the broad scope of this career path. In this article, we will discuss what software engineering is, what software engineers do and how you can start your career as one.
What Is Software Engineering?
Software engineering is the process of designing, developing and maintaining software systems. It is a branch of computer science that is concerned with all aspects of complex computer programming like design, implementation and maintenance and is responsible for the development of systems used in modern-day computers.
Software engineers mainly develop products that work on computer systems, but they also develop applications for high-end mobile devices and complex machinery. Software engineers can work in a variety of industries ranging from government to biotechnology.
What Does A Software Engineer Do?
A software engineer's roles and responsibilities depend on their industry and specialism. For instance, some engineers work as ethical hackers to develop systems and processes that help protect their client's computer networks against malware and phishing attacks. On the other hand, some software engineers specialise in designing interactive video gaming systems. While a software engineer's daily duties can vary widely, here are some common day-to-day responsibilities of a software engineer:
Examining and determining user needs: Analysing the system requirements of a primary duty of a software engineer. They analyse the specifications of the required software and do validations for the same.
Designing software: Designing the software includes defining the architecture, components, interfaces and other characteristics of the system or application. The design of software takes place through interface design, architectural design and details design.
Developing software: Developing the software is the main component in the software creation process. It is the process where programming, verifying, testing and debugging take place.
Testing end-user software: To check the quality of the software, it is necessary that empirical and technical testing is done. It is done to ensure that the product meets the end-user requirements. It ensures that the software is built correctly and there is no flaw.
Maintaining software: Software engineers update the already created software and perform maintenance. Modification in software is required as and when a fault occurs and software engineers are responsible for this as well. It includes error correction, optimisation, omission of unused and outworn features, and improvement of features that already exist.
Scope Of Software Engineering
Emerging as one of the fastest-growing fields, software engineering has a broad scope. Companies are constantly trying to upgrade their computer systems to stay relevant in this digital era. Software engineers can help them achieve this.
Depending on their knowledge and work experience, different candidates can qualify for different levels of software engineering jobs Here are some roles and responsibilities of different levels of software engineers:
In an entry-level software engineering role, you may work independently or with a team under the direct supervision of a lead software engineer depending on the size and scope of the company you are working in. Depending on its size, a company may have only one software engineer who is responsible for handling the company's systems or may have a large team of engineers working together to build world-class systems.
Gaining three to five years of experience in software engineering, you enter the intermediate level and can become a programmer analyst, data specialist or application developer depending on your specialisation.
With more than five years of experience in software engineering, you can advance to the role of a principal software engineer. In this role, you can work with the upper management of the company to analyse the needs of the business and prioritise the systems that need to be built. Senior software professionals work towards building scalable systems, managing more technical aspects of projects and increasing efficiency.
