What is the Diff Between A Software Developer and Engineer?

A software developer and a software engineer are roles within the tech industry that often overlap but have distinct focuses and responsibilities.

Software Developer:
A software developer is all about the software itself. This role involves writing code, designing applications, and implementing functionality based on requirements. Developers turn ideas into working programs, often working closely with clients or stakeholders to make sure the software meets user needs. Their tasks include coding, debugging, testing, and maintaining applications. Developers tend to be hands on with the software, working directly with the codebase and often specialise in specific programming languages or technologies.

Software Engineer:
A software engineer takes a more holistic and structured approach to software development. This role involves applying engineering principles to the whole software development lifecycle, from beginning planning and design to deployment and maintenance. Engineers deal with system architecture, scalability, and the integration of different components within the software. They are responsible for making sure the software is robust, efficient and maintainable. This role may also involve more collaboration with other engineers, project managers, and stakeholders to make sure the overall system design meets current and future needs.
In short, developers are all about the build and code. Engineers are about the design and overall system.
