It is the language of choice for developing Android mobile applications as well as back-end services. This has made Java developers highly sought after by large organisations around the world, creating numerous employment opportunities.

What are the duties and obligations of a java developer?

Becoming a Senior Java Developer requires more than what initially meets the eye. The primary role of a Senior Java Developer is to develop user interfaces for both intranet and internet applications. This includes designing Java applications, creating testable code, debugging software and examining program architecture. Although the exact duties of a Senior Java Developer may vary depending on the company and position, some of the most common responsibilities include:

  • Developing, deploying, and managing high-volume, low-latency Java applications.
  • High performance and uptime are provided.
  • Contribution throughout the development life cycle.
  • Creating competent, dependable, and tested software.
  • Software debugging, programming, testing, and analysis.
  • Supervise the creation and deployment of Java and Java EE applications.
  • Ensure that the design adheres to the requirements.
  • Create and distribute software component releases.
  • Convert the customer or businesses into specs.

How do you get to the position of senior Java developer?

The demand for Java developers is extremely high, making competition fierce for those seeking employment in this field. While many employers prefer applicants with a Bachelor’s degree in engineering, computer science, or a related field, a college degree is not always necessary as certificates from reputable non-traditional colleges are often accepted. Those hoping to obtain remote Java developer employment should have practical experience in software development, as well as a thorough understanding of relational databases, Java-based web services, SQL, and test-driven programming. Furthermore, commitment and hard work are essential for success in this area.

As a Java developer, proficiency in Java Standard Edition (SE) and thorough knowledge of its key features and terminology is a must. To get a good understanding of the fundamentals, it is recommended to start with free online lessons. After that, studying Java Enterprise Edition (EE) or Advanced Java is highly beneficial, as it contains features such as Java Server Faces and Servlets, which are essential for developing mobile and internet applications. It is quite difficult to keep track of all the components and technical terms involved in Java; therefore, online courses and coding boot camps can be extremely helpful in guiding and comprehending the essential concepts and information needed for becoming a successful Java developer.

All of the abilities required to become a successful remote Java developer are listed here.

Qualifications for becoming a senior Java developer

Java developers must be competitive in their jobs, and the following abilities will assist them in becoming in-demand professionals:

  1. Java skills

    As a Java programmer, you are capable of developing a wide variety of software, including web applications, desktop programs, mobile applications, and cloud systems. Additionally, you can use Java to create Big Data applications based on Python. It is important to be familiar with object-oriented programming principles, relational databases such as PostgreSQL, MySQL, and MariaDB, and popular version control systems like Bitbucket and Git. To make the development process easier, you should also make use of an integrated development environment (IDE) like IntelliJ IDEA. Finally, you should be knowledgeable about front-end web development technologies, such as HTML, CSS, and jQuery.
  2. Software architecture and design

    Software design and architecture are essential aspects of software development projects. As a Java developer, it is essential to be able to rapidly identify and deploy the best-suited technology stack and architecture for the application. Being knowledgeable in software architecture can help differentiate you from other developers and will be beneficial for your career progression.
  3. Spring Framework

    In 2020, more than two thousand websites leveraged the Spring framework to build Java applications. The framework is based on the Model-View-Controller (MVC) structure, which provides separate layers for business, operations, and presentation. Spring is renowned for its ease of use and attractive syntax, as well as for its ability to support object injection and automated testing with tools such as JUnit 5. Additionally, the framework’s use of explanatory notes helps to reduce tight coupling between classes and interfaces.
  4. Kotlin + Android

    Most Java developers begin creating mobile applications before they finish developing web applications. Acquiring an understanding of Kotlin while designing Android applications gives you an advantage and helps you to stand out. With Android, the platform is transitioning to Kotlin, which is an adapted version of the Java programming language.
  5. Testing of Individual Units

    As the complexity of a Java program increases, so too does the amount of labour required to support and implement automated tests, such as integration tests and unit tests, in order to launch the application. Developing and assembling a Java program can take a considerable amount of time, which is why technologies such as TestNg and JUnit are so useful. These frameworks provide support for the creation of automated tests, immediate feedback for successful tests, and have straightforward syntax. JUnit advocates a “testing first” strategy that not only enhances the stability of the codebase, but also increases the productivity of the programmer by reducing the amount of effort and debugging that needs to be done.
  6. SOLID Principles

    Object-oriented programming has revolutionised application design since its inception. Robert Martin, in his seminal work, introduced the concept of SOLID, which consists of five distinct principles of object-oriented programming. The Single Responsibility Principle states that each class should have a single, well-defined purpose; the Open-Closed Philosophy holds that classes, modules, and functions should be extensible but not modifiable; the Liskov Substitution Principle asserts that subclasses can be used as a substitute for their parent classes; the Interface Segregation Principle stipulates that interfaces should be designed with specific customers in mind and that clients should not be dependent on interfaces that are not utilised; finally, the Dependency Inversion Principle dictates that higher-level modules should not be dependent on lower-level modules.
  7. Tools for DevOps

    In order to fulfill their duties of adhering to coding best practices and creating scripts and manuals, senior-level Java developers must have a comprehensive understanding of DevOps technologies and concepts. This includes having knowledge of continuous deployment, continuous integration, and the role of Jenkins in both processes. Popular DevOps technologies such as Kubernetes, Maven, Chef, Docker, and Jenkins are necessary for Java engineers to master in order to be considered proficient in their field. Therefore, it is evident that DevOps expertise is an essential component of the top Java skills.
