What is Software Engineering?

In its true sense, software engineering refers to a field in computer science where client-centric software is developed after analyzing the requirements and insights from the users and other potential prominent sources.

  • During the development of the proposed software, a document  termed as  Software Requirement Specification (SRS) is followed. This is the document on which the foundation of the proposed software is laid.
  • Software engineering principles make sure that the to-be-developed software is reliable in all possible scenarios, flexible to all kinds of changes, pocket-friendly, has high uptime, and is assured by quality.
  • The concept of software engineering is easy to understand as  it is mostly theoretical. The learning curve is also not steep. 

Consider a real-life hypothetical scenario where you want to choose between two software products. One is developed on the principles of software engineering, and the other is developed based on assumptions. Which one will you choose?

Now it is the time to take you to the next section of the blog, which will tell you about software engineers in brief.

Who are Software Engineers?

If you want to define software engineers in a single word, then they are nothing but “Heroes” of the whole computer world. Software Engineers (SEs) are the enthusiasts responsible for developing and testing the proposed software, which happens to be highly optimized, cost-efficient, built for users, and built on users’ insights.

  • Software engineers also test the proposed system to finally present an error-free and fault-tolerant application for the users.
  • They write, review, and test the code and make the proposed changes by the other teams within the organization.
  • Software engineers are jack of all trades and masters of all. They are involved in multiple tech stacks and have appreciable knowledge in the domain.
  • They apply their summed-up knowledge of computer fundamentals, hard skills, soft skills, and the knowledge of developing new things from nothing to create something that didn’t exist before.

Isn’t It fascinating? Well, it is not easy to build something from nothing. Brace yourself, there is more to come.

Responsibilities  of Software Engineers

Responsibilities of Software Engineers

Below mentioned are the set of responsibilities that a software engineer is expected to do while working.

  • Understanding Client’s Specifications:
    • SEs interact with clients and potential users to understand the features of an ideal software.
    • After gathering the requirements and specifications, an object-oriented analysis is done and further proceedings are planned. 
  • Coding:
    • The development of the applications starts after gathering the requirements.
    • Multiple modules of the proposed system are written.
    • Languages like Python, Java, CPP, JavaScript, etc are used for development purposes.
  • Testing and Debugging:
    • Software engineers have to perform various types of tests on the to-be-deployed software.
    • The testing is performed based on various Software Development Life Cycle (SDLC) models.
    • SEs have to analyze the results and make the necessary changes.
    • They also prepare potential real-life test cases to evaluate the software.
  • Maintenance:
    • Once the software is deployed, regular maintenance is carried out by the SEs.
    • They have to monitor the deployed application periodically for performance competence with the industry standards.
    • This is as important as the development of software, as it makes sure that the software is performing well according to the test cases.
  • Innovation:
    • Implementation of new or previous modules based on the new stable technology.
    • For example, a previously deployed module was developed in C, and the updated one is developed in Java for aiming better performance and higher yields.

Types of Software Engineers

Types of Software Engineers

Software engineering is a  vast field with different types of subdomains associated with it. Every subdomain has its own specialized individual handler. 

Let’s explore the different roles a software engineer can take on.

  • Front-End Engineer:
    • They are solely responsible for the UI and UX development of the software.
    • Technologies like HTML, React, Angular, Bootstrap, etc are used for the development of very intuitive front-end designs.
  • Back-End Engineer:
    • These engineers are responsible for the development of the actual logic on which the whole application runs.
    • Back-end engineers design the optimized algorithms on which the software is built.
    • They work on technologies like PHP, Java, CPP, Ruby, Pearl, etc to design the backend of the software.
  • Full Stack Engineer:
    • Full-stack developers combine the front-end and back-end components of the program, making them the master of all crafts.
    • As they work with a variety of languages, they are the ones that receive the highest pay packages.
  • Software Engineer in Test (Quality Assurance Engineer)
    • QAs are responsible for ensuring that the software meets the quality standards set by the client.
    • They run multiple automated as well as manual tests on the application to validate the working quality of the software.
  • Security Engineer
    • They perform a vital role in the field of software engineering. 
    • They make sure that the proposed application is secured, and resistant to multiple cyber attacks.
    • They carry out multiple assessments on Vulnerability Assessment and Penetration Testing (VAPT).
    • They are solely responsible for maintaining the Confidentiality, Integrity, and Availability (CIA) triad. 

Now that you have a deep understanding of the role and responsibilities of a software engineer, let’s look at what it takes to become one.

Tech Skills Required by Software Engineers

Tech Skills Required by Software Engineers

Let’s start with the technical skills required to build a career as a software engineer.

  • Programming and Coding: 
    • This skill is the bedrock of software engineering. 
    • Through the use of programming languages, you can write programs to be executed by the computer system.
  • Data Structures and Algorithms (DSA): 
    • For hiring SEs, DSA is the most prominent skill tested by the assessors. 
    • Problem-solving, writing code, designing, analyzing, and optimization of algorithms are the most asked topics in interviews.
    • Being an expert  in DSA increases your chances of getting a highest pay package as an SE.
  • Object-Oriented Programming (OOPS):
    • Knowing OOPS is a must for all aspiring SEs as  working of most of the programming languages are based on OOPS.
    • Software engineers must have an understanding of various OOPs principles, which include data encapsulation, data abstraction, data hiding, polymorphism, and inheritance.
  • Testing and Debugging:
    • To make sure that the code is operating correctly, testing and debugging abilities are required. 
    • Errors are found by testing the code. Using debugging to fix them. 
  • Computer Fundamentals:  

You should have in-depth knowledge of computer fundamentals. Below mentioned are the subjects you should master if you want to be a successful SE. 

  • Computer Networking (CN)
  • Operating System (OS)
  • System Design (SD)
  • Database Management System (DBMS)

Soft Skills Required by Software Engineers
