What Skills Should You Look For When Hiring A Full Stack Developer?

In recent years, there has been a surge in demand for full-stack developers. Competition for top talent is strong, salaries are rising, and finding and hiring the right engineers at the appropriate moment is becoming increasingly difficult.

However, understanding what to look for is part of the problem of recruiting full-stack developers. Some skills are absolutely necessary, while others are not. If you’re looking to hire full-stack engineers in the near future, these are key skills to look for.

Who exactly is a full stack developer?

A real full stack developer is well-versed in all stages of software development. They are a jack-of-all-trades expert who understands front-end development (the portion that users interact with) as well as server and database development on the backend that runs the programme.

Typically, a programmer will specialise in one or two languages and frameworks, and they will be exposed to related technologies through their specialised job.

A typical path for software engineers to take is to study the whole stack of technologies for the product they are working on building.

As a result, a full stack developer is one who works on all aspects of a programme, from high-level frameworks to the servers that host the application components. A stack is sometimes defined as the core components of a programm, omitting things like servers and operating systems.

Nonetheless, the principle is the same: full stack engineers may work across several layers of the stack. They are not restricted to a particular aspect, such as the user interface.

Here is a list of skills to look for when hiring a full stack developer:

1. Hard Skills

i. HTML/CSS & JavaScript

Languages such as HTML, CSS, and JavaScript are essential components of full-stack development, and according to a 2018 Stack Overflow poll, professionals believe those three to be the most often utilised on the job.

These languages are important for the design of your company’s website, applications, or goods, and a full-stack developer should be fluent in all three.

ii. Server, Network, And Hosting Environment

Having knowledge in back-end development necessitates full-stack developers being able to programme in a variety of languages such as Ruby, Java, Python, and others. Furthermore, they must be familiar with basic server-side scripting and be able to give dynamic replies to clients.

iii. Database

Full-stack developers must be able to comprehend, construct, manipulate, and query databases in order to defeat the database management beast.

They must also be able to distinguish between relational and non-relational databases, as well as understand the syntax of XML / JSON.

iv. Git & Github

Git is a term that every developer, as well as prospective developers, is familiar with. It is a free and open-source “distributed version control system” that can handle all of your development requirements.

It offers efficiency and speed for both small and large-scale undertakings. Developers may use Git to manage any changes made to programmes, scripts, websites, documents, and other material related to software/application development in real time.

Professional developers often have a GitHub profile, which is required if they work in a team


REST is an interface between systems that uses HTTP to get data or create actions on that data in all conceivable formats. HTTP is the protocol that allows servers to interact with clients, and REST is the protocol that allows servers to communicate with clients.

In other words, the REST API serves as a “translator” between the Backend and the Frontend. As a result, understanding the relationship is equally important for a developer.

vi. Basic Design Skills

Given that a Full Stack Developer is involved with both the frontend and the backend, they must have basic design abilities.

Frontend design expertise is essential for making a website seem nice and inviting. A website with a clean and user-friendly design always wins over users.

2. Soft Skills

Full-stack developers serve as a link between many disciplines within a company, which necessitates the development of excellent soft skills.

This encompasses verbal and written communication, empathy, diplomacy, problem-solving abilities, and leadership abilities.

A candidate’s soft skills are frequently informed by their personality, which is another crucial element to consider when hiring.

Developers with hard talents who are unable to operate well on your team will not be successful. Personality and cultural fit must be considered during the recruiting process.


Full-stack engineers are valuable members of any team. They not only have a broad range of knowledge and expertise, but they are also adaptable, self-motivated, and quick learners. These traits not only make them effective engineers, but also wonderful people to work with.
