The technology industry is constantly evolving, which can lead to confusion with specific job titles for roles that share similar responsibilities. While some titles are quite distinct, titles like software engineers and software developers can be easily confused. Understanding the differences and similarities between these roles can be helpful if you're considering a career in IT. In this article, we explore software engineer vs. developer, explain what a software engineer does, highlight some essential skills and responsibilities, outline what a software developer does and their responsibilities and skills and explore the key differences between the two roles.

Software engineer vs developer

The software engineer vs. developer distinction involves some key differences and similarities regarding the main job tasks and responsibilities. These roles approach tasks and computer science differently. For example, a software engineer is likelier to experiment in software development, while a software developer rarely works in software engineering.

Despite the differences between these roles, some people working in computer programming use these two job titles interchangeably because software developers and engineers have similar traits. They're typically creative, logical, detail-oriented and excel at problem solving and maths. There's also an overlap in the hard skills necessary for both roles, although a software engineer usually requires a broader skill set than a software developer.

What does a software engineer do?

Software engineers apply engineering principles to create computer programs and manage data. Their role can involve developing and designing software solutions that meet their client's requirements. They typically work in various industries and may specialise in web applications, operating systems, databases or content management systems. Software engineers usually possess excellent knowledge of data structures, algorithms, web development and best practices in systems engineering. In addition to developing software, they also incorporate testing and analytics into their work and regularly communicate with stakeholders from various backgrounds, meaning good communication skills are important.

Software engineers are highly skilled in maths and science. Problem-solving is a part of their role, helping them to look at problems methodically and using scientific methods to help explore potential solutions. This assists in designing comprehensive and practical solutions to meet their client's requirements.

What does a software developer do?

Software developers are responsible for providing coding for software development. They use their knowledge and skills to write, modify and debug software. Developers also analyse concepts and develop documents. Some can be responsible for designing, testing and optimising software to ensure it works as expected. Software developers may work closely with a broad team of colleagues, from product managers to customer service operators, to ensure they develop software that best suits the requirements of both the customers and stakeholders. Servicing multiple stakeholders can mean they respond to various types of feedback and changes from different users and team members.

Most developers rely on their knowledge of various types of program languages and codes to complete their tasks. They're typically involved in the entire product development cycle, including research, testing, development and launch. Software developers usually work on a specific function or are responsible for developing a particular aspect of a project rather than an entire system. Many software developers specialise in a particular development framework, usually obtaining their qualifications via a formal degree or diploma course, specialising in computer systems or software engineering.

Key differences between a software engineer and a software developer

Although there's some overlap, there are distinct differences between the responsibilities and skills of software engineers and software developers. Software engineers usually apply software engineering principles when ‌designing, developing, maintaining, testing and evaluating software. While software engineers can get involved with software development, software developers are rarely engineers. Some other key differences include the following:

Client interaction

Software engineers use systematic processes and engineering concepts to connect their client's requirements to specific technological solutions. Then, a software developer collaborates closely with the client to work out the functional design. This means developers are typically the creative driving force behind innovation and development for various types of software.

Software developers typically focus on creating functional programs. They can do this using art and creativity. In contrast, a software engineer draws on the knowledge and experience from formal study, using scientific methods and engineering principles to create reliable solutions.

It can be helpful to think of a software engineer as a project architect and a software developer as a carpenter. While engineers rely on knowledge gained through education and specific processes and protocols, developers usually take a different approach. They often use practices gained through external sources or self-discovery rather than relying purely on formal educational learning.

Overall role

When considering a software engineer a project architect, a software developer does the execution portion. An engineering designer oversees and coordinates the project. The developer uses the plans by the engineer to write the code that brings the project to life.
