An example of a back-end developer job description is below:

We are seeking a back-end web developer to manage data between web servers and end users in our latest projects. Along with a team of other dedicated developers, you’ll mostly be responsible for maintaining server-side business logic. 

By collaborating with front-end developers who work on client-side behavior, you will play a direct role in delivering fast and efficient services to our client base. 

Roles & Responsibilities

Detail the day-to-day tasks that your back-end developer can expect to perform. A mid-sized bullet point list usually does the job. To be clear, this is where you want to go in detail. Be pointed about industry language and technical terms where possible.  

These are some of the roles and responsibilities of a back-end developer:

  • Build and implement data storage solutions
  • Find scalable and efficient development solutions 
  • Supervise server resources and cross-platform optimization across Internet browsers and operating systems
  • Use databases, web servers, wireframe development, and UI/UX design in development procedures 

Skills & Qualifications

At this section, you can start narrowing down your applicant base by outlining the minimum requirements you’d like your potential hires to have. Of course, these requirements should be fairly reasonable and tailored to the project(s) you have in mind.

Your requirements may look something like this:

  • At least 5 years of back-end development experience 
  • Experience with backend services like containers, kubernetes, and cloud technologies like Amazon Web Services (AWS)
  • Fluidity coding in multiple back-end languages such as Python, Node.js, and PHP
  • Sufficient background using PostgreSQL

What Are the Most Common Roles and Responsibilities of a Back-End Developer?

Back-end developers should have the wherewithal to work on the server-side of all development projects. These primarily involve web development where a back-end developer will provide the infrastructure necessary for user-facing content to perform well.

To do this, back-end developers must have a somewhat abstract understanding of code. Codebases on the back-end will often go far deeper than a simple ‘print’ function. 

This is not to say that front-end development is not complex. But their skills revolve more around building navigable features and graphic content.

Back-end developers, on the other hand, deal with databases and/or storage solutions that inevitably bridge to the functionality of the front-end. For example, a user’s input on the client-side will be stored and manipulated on the server-side.

What Are the Skills Required For Back-End Developers

Much of a back-end developer’s work includes steering the part of a website or application that users never think twice about. Several tools are required to do this. And professional back-end developers should be familiar with these tools and how to operate them.

First and foremost, back-end developers code in programming languages that are well-suited for server-side operations. Java, Ruby, PHP, and Python are some of the more common languages used for back-end development.

These languages are optimized for back-end development because of their affinity for memory management as well as frameworks like Ruby on Rails for Ruby and Django for Python that make web development easier.

In addition to traditional programming languages, back-end developers should have experience using a query language, namely SQL. Query languages are used in databases and information systems to parse through and return data.

MySQL, Oracle, and PostgreSQL are among the most popular tools for database management, where using SQL is requisite.

Besides competency in languages of this sort, back-end developers should be acquainted with other technologies that contribute to back-end interactions. This, for instance, may include cloud computing mechanismsAPI integrations, operating systems, security management, and more.

How Much Does a Back-End Developer Cost

Based on several hundred anonymous salary reports, Glassdoor estimates that the average back-end developer makes $101,619 annually. This is based on the United States and will greatly fluctuate depending on the region.

Given a typical work week, the aforementioned annual salary reflects an hourly wage of $48.86 per hour. If you decide to hire a full-time back-end developer, this is a good approximation of what that hire will cost.
