What is a Software Developer?

A software developer is a professional who is responsible for writing, testing and maintaining software code. The role of a software developer is primarily focused on the technical aspects of software development, such as coding and debugging. So, where a software engineer is often focused on the design, development and testing of entire computer systems, a software developer may focus more on specific applications or parts of the software. Many software developers even specialize in certain programming languages or types of development — like mobile, front-end or web — in order to set themselves apart in the job market and gain greater expertise in the tools of their trade. 

Responsibilities of a Software Developer

Just like with software engineers, the responsibilities of a software developer can vary depending on the organization they work for, as well as the specific project they are working on. However, some common responsibilities of a software developer may include:

  • Writing, testing and debugging code for software applications
  • Collaborating with other members of a development team to solve technical challenges
  • Participating in code reviews and providing feedback to colleagues
  • Staying up-to-date on industry trends and best practices
  • Working with end-users to identify software needs and requirements
  • ​​Writing automated tests to ensure software quality and reliability

Unique Skills Required for a Software Development Role

Software development requires a unique set of skills that are focused on technical abilities and attention to detail. While a software developer must be able to work well with others and communicate effectively, their primary focus is on writing high-quality code. Some of the key skills required for a software development role include:

  • Strong coding skills in one or more programming languages
  • Attention to detail and a focus on writing high-quality code
  • Knowledge of software development best practices and methodologies
  • Ability to connect the big picture to the smaller components of a system or application
  • Familiarity with software testing and debugging processes
  • Knowledge of algorithms and data structures 
  • Time management skills
  • Creativity

What are the Differences Between a Software Engineer and a Software Developer?

While the terms software engineer and software developer are often used interchangeably, there are noteworthy differences between the two roles.

Scope of Work

The primary distinction between software engineers and software developers is in the scope of their work. Software engineers focus on the big picture — the entire software development life cycle – from requirements planning and analysis to the testing and deployment of new software. They leverage their extensive knowledge of programming languages, computer operating systems, advanced mathematics, and software development best practices to determine the best way to build and maintain complex software systems. Software engineers focus on, for example, how, where, and what data is stored. Or what tools to use to ensure a smooth integration with the existing codebase. 

Software developers, on the other hand, focus on the “development” phase of the software development life cycle. Their work involves building the individual components of a software system — often components they have specialized knowledge in – like front-end or back-end systems or mobile applications. They work with engineers to understand the requirements and design specifications, and then implement them.

Think of it like a restaurant kitchen. Software engineers are like the head chefs, creating the menu, choosing ingredients that complement one another and determining the right methods for cooking and preparing the food. And software developers are like the line cooks. They take the head chef’s vision and bring it to life, executing the recipes to perfection.

Focus on Technical Skills

While both software engineers and software developers require strong technical skills, their different focuses lead to specialization in different skills.

Software engineers tend to be more involved in the early stages of software development, such as requirements gathering, system design, and architecture planning. This requires engineers to have greater proficiency in a range of programming languages, frameworks, tools, and operating systems, as well as a broad understanding of various methodologies, trends, and best practices. They need to know how all the moving parts will work together in order to design software systems that are scalable, maintainable and efficient. 

Software developers, on the other hand, tend to focus more on the coding and testing of smaller-scale projects and may work more closely with end-users to ensure the software meets their needs. While they may possess many of the same technical skills as an engineer, their knowledge tends to be more focused and specialized, giving them a deeper understanding of the limitations and possibilities of specific software tools or programming languages. They take an engineer’s design specifications and find the best way to implement them in the code.

Education and Training

Software development is often seen as a subset of software engineering, so when it comes to education and training, there can be a fair amount of overlap between software engineers and software developers. But the level of education and training required for these two roles can and often does differ. 

Given the broader scope of a software engineer’s work, they’re often required to have more comprehensive technical education. They learn how to apply engineering principles and the scientific method to the entire software development life cycle, and are educated in subjects like systems design and analysis, software validation and testing, and software architecture. Some companies may even require a bachelor’s or master’s degree in computer science, software engineering, or a related field. However, with the rise of engineering bootcamps and more accessible online learning resources, there are more opportunities than ever for engineers without traditional education backgrounds.

A software developer may choose to take a similar educational path as a software engineer, allowing them to work in either role, or specialize in a particular programming language or type of software development. While software developer roles are less likely to require a college degree, many developers still choose to pursue higher education for the strong skills foundation — and leg-up in the job search — that a degree can provide. However, given that software developers’ main focus is on writing high-quality code, they often need less education than an engineer, which can make it easier to get started in a career as a software developer — particularly for people who are self-taught or don’t have a traditional coding background. 

Job Titles and Roles

Another difference between software engineers and software developers is their job titles and roles within an organization. Software engineers are often seen as senior-level professionals who oversee the design and development of software systems and may be involved in managing other members of a development team. Software developers, on the other hand, are typically seen as entry- or mid-level professionals who are responsible for writing and testing code and may work under the guidance of a software engineer.

How to Choose the Right Role for Your Team

Despite these differences, the lines between software engineering and software development can sometimes be blurred, and many professionals have skills and experience in both areas. Many organizations use the terms interchangeably, and the roles and responsibilities of software engineers and software developers can overlap depending on the size and scope of the project they are working on. 

For hiring managers looking to add software professionals to their teams, the choice of which role to hire for will depend on the specific needs and goals of the organization, as well as the skills and experience of the candidates being considered. 

Remember: software engineers work on the macro-level, while software developers work on the micro-level. If the team is focused on large-scale and complex software development projects with multiple components and integrations, a software engineer may be the right choice. But if the team is focused on coding and testing, say, a new mobile application for an existing system, or needs someone with expertise in a specific programming language or framework, a software developer may be a better fit. 

The size of a company can also be a determining factor. Startups, for example, often operate with leaner teams, which means they need software engineers who can act as both engineer and developer. Enterprise businesses with more robust software teams generally have more resources available to hire both engineers and developers, which allows them to take advantage of the specialized knowledge developers can bring to the table.
