Senior Java Developers

Recruit Experienced Java Developers

Java is a popular and versatile programming language that has been used by numerous organizations of all sizes both nationally and internationally. Its portability and maintainability make it an excellent choice for building various applications, ranging from everyday tools such as the Wikipedia search engine to complex systems such as the Maestro Mars Rover Controller and Hadoop. Moreover, Java is known for its “write once, run everywhere” approach, enabling developers to compile code and run it on any platform that supports Java. This language is highly versatile, user-friendly, and entirely free, making it a valuable tool for businesses. Pursuing a career as a Java programmer can also offer stable and lucrative employment opportunities. Besides, as more companies choose to outsource their expertise, the demand for remote senior Java developers is continually increasing.

What is the extent of Java development?

Java is a versatile and robust programming language that can be used in various contexts, ranging from laptops and supercomputers to mobile phones and other devices. Java is easy to learn, use, write, debug, and teach compared to other programming languages, making it an attractive choice for developers with varying levels of experience.

Despite being a programming language that has been around for over two decades, Java’s popularity remains high, and it is still widely trusted by developers. It is the go-to language for developing Android mobile applications as well as back-end services, making Java developers highly sought after by corporations worldwide and creating numerous employment opportunities.

What are the responsibilities and duties of a Java developer?

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

  • Developing, deploying and overseeing Java applications with high volume and low latency.
  • Ensuring high performance and uptime.
  • Contributing throughout the entire development life cycle.
  • Developing reliable and tested software that meets the required standards.
  • Debugging, programming, testing, and analysing software.
  • Overseeing the development and deployment of Java and Java EE applications.
  • Ensuring that the design meets the specified requirements.
  • Developing and distributing software component releases.
  • Transforming customer or business requirements into specifications.

What are the steps to becoming a Senior Java Developer?

Competition for employment as a Java developer is intense, given the high demand for such roles. While candidates with degrees in engineering, computer science, or related fields tend to be favoured by employers, a college degree is not always mandatory, as suitable certificates from reputable non-traditional colleges can be accepted. Candidates looking for remote Java developer positions should have hands-on experience in software development, as well as a thorough understanding of relational databases, Java-based web services, SQL, and test-driven programming. In addition, commitment and hard work are crucial for success in this area.

As a Java developer, proficiency in Java Standard Edition (SE) and an in-depth understanding of its key features and terminology is essential. It is recommended to start with free online lessons to gain a good grasp of the fundamentals. After that, a thorough knowledge of Java Enterprise Edition (EE) or Advanced Java is highly beneficial. Java Server Faces and Servlets are necessary for developing mobile and internet applications. Given the multitude of components and technical terms involved in Java, 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.

Here are all the skills required to become a successful remote Java developer.

Requirements for becoming a Senior Java Developer

To be successful as a Java Developer and stand out in their field, professionals should possess the following skills:

  1. Proficiency in Java

    As a Java programmer, it is vital to be capable of developing various software, such as web applications, desktop programs, mobile applications, and cloud systems. Additionally, you should have knowledge of using Java to create Big Data applications based on Python. You must have a sound understanding of object-oriented programming principles, relational databases like PostgreSQL, MySQL, and MariaDB, and popular version control systems like Bitbucket and Git. To streamline the development process, you must utilize an integrated development environment (IDE) such as IntelliJ IDEA. Having knowledge of front-end web development technologies, such as HTML, CSS, and jQuery, is also essential.
  2. Software Architecture and Design

    Software design and architecture are critical elements of software development projects. As a Java developer, it is crucial to effectively identify and deploy the most appropriate technology stack and architecture for the application. Having expertise in software architecture can set you apart from other developers and contribute to your career advancement.
  3. Spring Framework

    In 2020, over two thousand sites used the Spring framework to create Java applications. The framework is founded on the Model-View-Controller (MVC) architecture, which provides dedicated layers for business, operations, and presentation. Spring is popular for its user-friendly and enticing syntax, as well as its capability to support object injection and automated testing using tools like JUnit 5. Furthermore, the framework uses explanatory annotations to minimize tight coupling between classes and interfaces.
  4. Kotlin + Android

    Many Java developers start creating mobile applications even before completing web applications. Having knowledge of Kotlin while developing Android applications can give you an edge and help you stand out. The Android platform is gradually shifting to Kotlin, which is an improved version of the Java programming language.
  5. Unit Testing

    As the complexity of a Java program increases, the amount of effort required to implement automated tests such as integration tests and unit tests also increases in order to launch the application. Since developing and assembling a Java program can take a considerable amount of time, technologies like TestNg and JUnit are extremely beneficial. These frameworks facilitate the creation of automated tests, provide immediate feedback for successful tests, and have simple syntax. JUnit follows a “testing first” approach that improves the stability of the codebase while also increasing the productivity of the developer by reducing the amount of effort and debugging required.
  6. SOLID Principles

    Object-oriented programming has brought significant advancements in application design since its inception. Robert Martin introduced the concept of SOLID, which comprises 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 Principle prescribes 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 mandates that interfaces should be designed with specific clients in mind and that clients should not be dependent on interfaces that are not utilised; finally, the Dependency Inversion Principle directs higher-level modules should not be dependent on lower-level modules.
  7. DevOps Tools

    Senior Java developers are required to adhere to coding best practices and develop scripts and manuals. It is therefore essential for them to have a thorough understanding of DevOps concepts and technologies including continuous deployment, continuous integration, and the role of Jenkins in these processes. Popular DevOps technologies like Kubernetes, Maven, Chef, Docker, and Jenkins are necessary for Java developers to master in order to excel in their field. DevOps expertise is therefore an indispensable component of the top Java skills.
