What Is a Software Developer? Learn Everything You Need To Know

Learn about what a software developer is, their job responsibilities and how to become one.

What Is a Software DeveloperMost of our days are spent interacting with technology. In order to power these technologies, we need one critical component – software. Software refers to the programs, instructions and other information that tells a computer what to do and how to do it.

But software is more than just coding and creating apps. Software plays a vital role in the economy, and it acts as the driving force behind every digital device and computing system that we use.

As technology continues to advance, the role of software becomes increasingly important, creating a growing demand for software developers. In fact, there were more than 1.2 million job postings for software developers in the United States in 2022 according to Lightcast.

You might be thinking:

  • What exactly does a software developer do?
  • How much money can I make?
  • How do I become one?

Let’s answer these questions and explore how you can kickstart your career in software development.

Role and Responsibilities

Software developers – sometimes referred to as a software engineer – are the masterminds behind a variety of programs. Software developers design, create, evaluate, modify, maintain and configure software solutions for computer systems to meet user needs and client specifications.

They may also oversee the entire software development lifecycle, conduct research, debug code, deploy upgrades and build diagrams and models to communicate end results.

A day in the life of a software developer may also involve:

Meeting with internal and external clients to discuss desired outcomes and project scope

Working individually or with other programmers, designers and QA analysts as part of a team

Verifying and validating proper functionality of applications

Creating flowcharts and logic workflows

Performing requirements analysis and functional unit tests to identify gaps and other potential issues

Troubleshooting and improving existing applications and software

Analyzing and formulating software requirements

Reviewing system performance and evaluating results

Writing code and implementing larger frameworks to support specific devices or technologies

Developing and maintaining technical documentation as a reference for functions and use cases of applications


For team leaders or project managers working in the software development space, working in an agile environment requires frequent feedback and iterative development to deliver software programs faster, optimize operational efficiency and adapt to meet evolving needs.

Types of Software Developers

Software development is a broad field, and developers often work on large, complex projects, making it difficult to have every required skill and an in-depth understanding of all development environments.

This is why most software developers fall into two main classifications:

  1. Applications software developers
  2. Systems software developers

Both groups perform similar tasks but focus on different aspects of development and computer programs; some focus on a specific program or application, while others create systems that power other programs or networks. Regardless, career prospects for all types of developers are in abundance.

Within the two main groups of software developers, there are different specializations that tech pros might pursue based on their specific skill set and/or interest.

Applications Software Developers

Applications software developers focus on designing and developing applications for computers and mobile devices. They might create custom programs for a specific customer to be sold, an organization’s internal network or for the general public.

Types of applications software developers include:

Systems Software Developers

Systems software developers are responsible for building, overseeing and optimizing operating systems-level solutions for consumers or enterprise organizations, as well as the implementation and documentation of system architecture.

Operating systems are what keeps computers functioning; it serves as an interface between a user and computer hardware, manages system resources and provides a platform for applications and programs to run on. It can be found in most of the technology we use, so it’s crucial to have tech pros who are skilled in building and ensuring that those systems remain functional.

Types of systems software developers include:

Skills Required To Become a Software Developer

In today’s technology-driven world, software developer skills are highly valuable, and demand is at an all-time high. In fact, employers listed 3.9 million job postings in the United States seeking candidates with software development related skills during 2022, according to Lightcast.

Step 2: Pursue a Degree, Bootcamp or Certification Program

Pursuing software development-focused degree programs, bootcamps and certifications build the skills and knowledge you need to boost job opportunities and fast-track your career.

Pursue an Undergraduate Degree

Software developers typically have a high school degree, vocational training, or an associate or bachelor’s degree in computer information systems, computer science, software development, software engineering, information technology or a related field. Students often select specializations during this time. As the field becomes more competitive, you might consider pursuing a master’s degree to advance your career and stand out among the competition.

Complete a Bootcamp

Bootcamps generally last three to six months through online, in-person or hybrid formats, making it a popular option for those who don’t have the time and/or money for a four-year degree. They offer hands-on learning and equip individuals with the necessary skills to prepare them for their first software development job. Some may start with bootcamps before pursuing an undergraduate degree, while others may already have a bachelor's degree in another field and enroll in bootcamps to pursue tech roles.

Earn Professional Certifications

Another way you can verify your skills is by earning industry-recognized certifications. There are a variety of reasons to get certified, like having a competitive advantage over other job candidates or helping you advance your career.

Some software developer certifications include:

When deciding which certifying body to choose, make sure to take into consideration each institution's quality, affordability and reputation. And even after you get your first software developer job, it’s important to keep pursuing continuing education opportunities to remain up to date with the latest technologies and broaden your skills as your career progresses. If you’re already pursuing a degree, check to see if your current curriculum includes certification preparation and examination.
