As technology continues to evolve and advance, the term "software developer" has become too general to comprehensively describe the specific and technical skill sets that individuals need to succeed in a role. Due, in part, to open-source framework and ongoing language development, new ways of building and maintaining software consistently emerge.
Instead of memorizing the differences between Python, Java, or C++ developers, it may be more practical to categorize these roles by their development function. For example, front-end development may include several sub-types of developers who are fluent in CSS, HTML 5, or JavaScript. Due to the volume of existing and new developer sub-types, it’s likely more practical to have a functional understanding of a candidate’s role in the team.
When deciding who to hire, it’s critical to maintain alignment between key technical leaders, recruiters, and HR to identify the right candidates early in the process. Further, candidates who are properly vetted for the right set of technical skills will likely contribute to a stronger engineering team culture and more positive hiring metrics. Having a foundational understanding of a developer's role and identifying some of the core tools they use is the first step in mitigating tech hiring issues.
Here are 15 different types of developers you may want to consider for your next hire.
1. Front-end Developers
Front-end developers, also known as client-side developers, primarily program user interfaces (UI). They design and create the layout of websites, and their code runs through a browser and opens on the user's computer. Any website a user interacts with results from a front-end developer’s work.
Front-end and UI developers must not only know how to write code but also understand how people interact with machines. This understanding allows them to create intuitive interfaces accessible to all users regardless of skill level or ability. Additionally, front-end developers often collaborate with back-end developers, who handle the server-side operations.
