In software teams, it often happens that the team’s different roles are interconnected, and therefore it’s easy to mix them up. You might think that a backend engineer has the same roles and responsibilities as a backend developer. After all, they are part of a software team with the same project. They might even end up doing similar tasks, especially in software development Agile teams where members take cross-functional responsibilities to successfully achieve their goals.
However, the truth be told, a backend engineer is not the same as a backend developer. They do have different responsibilities and skills that, despite having similarities, also define what they bring to the table when developing software. This article put together with our Recruitment Director, Ihor Shcherbinin, will explore each role, analyzing its main characteristics and the difference between the backend developer and engineer.
What is Backend Development?
Websites and applications sometimes seem as if they worked with magic. When you’re visiting a website, you click buttons that take you to different categories, for example, our blog. Or, when you’re on websites like Amazon, you have to fill out forms with your personal information to buy something. But how does that happen? Where does that information go?
It goes to a place called the back-end. The backend simply explained refers to the development of server-side logic that powers websites and applications. It’s the behind-the-scenes part of all the actions we take in a site.
Backend development primarily focuses on databases, scripting, backend logic, APIs, and website architecture.
What differentiates backend development from frontend development is the fact that the frontend, also called the client-side programming, is what happens in the browser and what all users see and interact with. For example, a simple pop-up is a product of the front end. On the other hand, backend development is everything users can’t see, but that powers everything that happens on a website.
What is a Backend Developer?
A backend developer is responsible for writing the web services and APIs used by front-end developers and mobile app developers. They oversee the server-side web application logic as well as the integration of the front-end part.
Besides being in charge of the server-side logic, their primary focus is to define and maintain the central database, making sure that it has high performance and responsiveness to requests from the front-end.
What Does a Back-end Developer Do?
While the back end engineer has the role of the chef, the back end developer would be the sous-chef. He/she understands what must be done to create the perfect dish and knows how to execute it. The back-end developer understands the structure built by the backend engineer and focuses on features or tasks to make the development of the software possible.
Backend Developer Skills
- Integration of data sources and databases into a single system.
- User authentication and authorization between multiple systems and servers.
- Expertise in JS, ReactJS, VueJS, AngularJS, and jQuery.
- Write clean and maintainable code.
- Understanding cross-platform functionality and compatibility of applications.
Backend Developer Responsibilities
- Troubleshoot and debug applications.
- Conduct UI tests and optimize performance.
- Participate in the application lifecycle.
- Develop sustainable web applications with clean codes.
- Provide training and support to other team members.
What is a Backend Engineer?
A backend engineer is responsible for designing, building, and maintaining the server-side of web applications. In other words, a backend engineer’s primary responsibility is to build the structure of a software application.
They set the software team’s foundations of what they need to do to achieve the main goals. This means that one of the primary functions of a backend engineer in a software development team is to write business logic, server scripts, and APIs that will later be used by the other developers and members of the team.
The day-to-day backend engineering consists of optimizing servers for speed and stability, ensuring the structure is secure, and generating reusable code libraries and data storage solutions.
Backend engineers are also in charge of:
- Optimizing servers for speed and stability.
- Building security structures.
- Generating reusable code libraries.
- Creating data storage solutions.
What Does a Back-end Engineer Do?
Backend engineers have a set of skills that are necessary to perform their jobs efficiently. As stated above, they are the ones who set the path for the software team.
They oversee building the structure that a software application has. Backend engineers spend time writing server scripts and APIs that front-end engineers and UX designers will later use.
Backend engineers work on the server components of multi-tier web applications focusing on web services and data stores. Additionally, they may be involved with business rule implementation logic.
Backend Engineer Skills
- Knowledge of Java, HTML5, and CSS3.
- Server-side experience with SASS and Less.
- Understanding of accessibility and server compliance.
- Solid OOP and software design knowledge.
- Knowledge in database systems.
Backend Engineer Responsibilities
Besides the tasks explained above, a backend engineer also has these responsibilities:
- Regularly inspect server code for speed optimization.
- Conceptualize and implement solutions for data storage.
- Improve the quality of the team’s code through writing unit tests and automation.
- Collaborate and work closely with the product and design team to understand better the end-user requirements.
- Configure the backend usability of all front side application.
Backend Programming Languages
Backend development has 2 different types of programming languages:
1. Object-oriented (OOP)
This programming paradigm is based on the concept of classes and objects, which can contain data and code. Data in the form of fields and code in the form of procedures.
Its purpose is to transform a program’s structure into simple, reusable pieces of code snippets (classes) that are used to create individual instances of objects.
In OOP, computer programs use objects that talk to one another, changing the data in those objects and working in a way that the user wants.
Some of the popular object-oriented backend languages are:
Functional programming consists of a paradigm where programs are constructed by applying and composing functions.
In this programming paradigm, function definitions are trees of expressions that map values to other values rather than a sequence of imperative statements. Functions can be bound to names, passed as arguments, and returned as other functions.
Some of the popular functional languages are:
Within these two different programming paradigms, these are the most popular programming languages used in backend development:
PHP – Hypertext Preprocessor – is one of the core programming languages in the web development world. This server-side scripting language is usually used to gather the user’s information and store it safely in a database.
Python’s popularity has increased during the past years mainly because of its compatibility with advanced technologies like Machine Learning and the Internet of Things. Python’s major benefit is its extensive collection of standard libraries that make the work of developers comparatively easier. Additionally, Python has unique features to help developers with better code readability, integration with other languages, and GUI programming support.
Java is one of the core programming languages for backend web development. It is popularly used for developing enterprise-scale web apps as well as android, desktop, and scientific applications. Java is characterized by its cross-stage capabilities and security. Developers can perform database connectivity, image processing, network, etc.
Ruby is a dynamic and open-source programming language that focuses on productivity and simplicity. One of its advantages is that it allows developers to create web apps without writing much code. They can automate repetitive tasks, build both website and mobile applications, and develop prototypes. Additionally, Ruby supports almost every major platform like Windows, Mac, and Linux.
During the last few years, C# has ranked under the top 5 programming languages. It is extensively being used in areas such as the development of Windows applications, game development, etc. The language provides faster compilation, interoperability, component-oriented and structured language, and many others. Additionally, it has a rich set of libraries that helps developers program faster and efficiently.
Skills and Tools Required for Backend Development
At a general level, backend professionals (both engineers and developers) require at least some formal training to acquire the basic skills. Many have degrees in computer science or advanced mathematics; others have courses related to the career itself.
The skills change depending on the job demands as backend development takes care of different aspects and parts. However, apart from the languages mentioned, there are other skills every backend expert needs to have, such as:
- Deep understanding of deploying or hosting.
- Knowledge of version control (Git and GitHub).
- In-depth understanding of accessibility and security compliances.
- Ability to manage a hosting environment along with database administration.
- Understanding of scaling applications to handle the load changes that is a large amount of data traffic.
- In-depth understanding of algorithms and data structures.
Back-end Engineer vs Back-end Developer: Main Differences
The backend engineer vs. backend developer discussion takes place because they have similar tasks and responsibilities, as seen above. However, the main difference relies on the fact that a backend engineer is mainly responsible for communicating with the company’s leaders to understand the end-user necessities. This helps them have a more comprehensive panorama into what the application’s development should be and should look like.
On the other hand, a backend developer is mostly responsible for executing the backend engineer’s plans. They have single tasks, and features that combined made the development of software applications possible.
In other words, developers are not responsible for designing the entire development system, while engineers are. Backend engineers have to demonstrate that the design and methods they’ve made for the project are viable.

As in most careers, a back-end developer’s salary depends on two main factors:
1) Their level of expertise
In the United States, IT professionals tend to charge expensive salaries, even when it comes to junior roles. For instance, PayScale data reports that an entry-level end developer in the U.S. earns around $61,042 per year. A backend developer with 1 to 4 years of experience earns $70,965 per year. And an experienced backend developer with 5 to 9 years of experience can expect an average of $87 500 per year.
Remote backend developers’ salaries tend to be lower. As mentioned, it depends on the area they live in, but for example, according to Glassdoor, a senior backend developer in Argentina can expect to earn between $31,913 to $42,180. In other countries such as Germany, a senior backend developer makes an average of $64,450 per year.
In regards to hourly rates, a backend developer ranges globally from $ 65-100.
Like backend developers, a backend engineer’s salary depends on their skills and experience and their location.
According to PayScale and Ziprecruiter, a junior backend engineer in the U.S. can expect a salary of $68,388. A mid-level backend engineer earns an average of $95, 864 per year. And a senior backend engineer earns approximately $137, 369. In other countries the salary changes. For example, a senior backend engineer in France earns $77,950 per year.
While it depends on the type of website or application you want to build, overall, the top 8 languages for backend development are:
Python – Used in Instagram
Ruby – Used in Github
C# – Used in Microsoft Visual Studio
PHP – Used in WordPress
Java – Used in Twitter
Perl – Used in BBC
C++ – Used in Adobe Photoshop
One of the most common perceptions is that learning frontend development is easier than learning backend. The truth is that on a beginner’s level, the front end tends to be easier. But when it comes to an in-depth understanding, both can have the same difficulty and complexity as they require patience and discipline.
