When it comes to object-oriented programming (OOP), nothing beats JAVA. A platform to make applications and share them across the systems, it is one of the most used programming languages in the IT industry.
Therefore, Java developers have become an absolute necessity for any organisation. However, Java’s changing nature and its prevalence in the industry can sometimes make it challenging for employers to hire remote Java developers for their development needs. For your Java needs, You can source your talents from social communities where the talent is waiting to be discovered.
Here, we have created a checklist, a complete guide, to pick the right person that caters to what you are looking for and promises sustained individual and organisational growth.
Who is a Java Developer?
More than 9 million developers use Java as their programming language thanks to its ease of use and its demand. Today, more than 7 billion devices make use of Java, including 3 billion mobile devices, according to the codeinstitute. The developers have built all the popular apps that we use.
A Java developer works in designing, developing, and building applications with dynamic elements of Java.
Skillset to Look Forward To
While hiring a remote Java developer, you may come across many profiles. Sometimes, it may get tough to filter who would be the perfect candidate for the skills your project would require.
Here is the skillset to look forward to when hiring the best remote Java developers. Remember, a Java Developer may not need to possess all these skills; it will completely depend on your project needs.
1. Fundamentals of Java
These would be the basic skill set of a Java developer. The core Java fundamentals include object-oriented programming concepts and static, nested and default interface methods. They should also be familiar with serialization and deserialization.
2. Web Technologies
3. Java Frameworks
Frameworks are templates for reference for Java developers. It helps developers create new applications without writing the code from scratch. Some popular frameworks include Spring; Java Server Faces, Hibernate, Google Web Toolkit, etc.
4. Design & Architecture
These are some advanced Java developer skills that an experienced candidate would possess. These skills include creational, structural, behavioral, and miscellaneous design patterns.
5. DevOps Tools
The DevOps tools are not limited to Java programming only. They help in the continuous integration and development of your project. Some of the handy DevOps tools your candidate may know about our Apache ANT, Git, Docker, Apache Maven, Jenkins, Docker, Chef, etc.
If you are hiring remote Java developers for a project that deals with Big Data, they should understand the nuances of database management systems. Some advanced skills would include SQL (structured query language), NoSQL, Oracle, Tableau, Apache Hadoop, etc.
7. Testing Tools
A developer writing code with any programming language should know how to test it once written. Tools like JUnit, Selenium, TestNG, and Mockito are some of the popular Java unit testing frameworks used for testing Java codes.
8. Class Design Principles
The core concepts of Java ensure that the application a developer has created is easy to understand, maintain, debug, refactor, and modular. It will save time and effort in development without compromising the quality. These concepts for object-oriented designs are represented by the acronym: SOLID. It stands for Solid responsibility, Open/Closed (expansion and modification), Liskov substitution, Interface Segregation, and Dependency Inversion.
9. Java Virtual Machine
Java Virtual Machine (JVM) allows Java applications to write once and run anywhere. This would make them platform independent. The JVM also analyses and executes Java bytecode. Understanding the functioning of JVM is not an essential skill to have, but at the same time, it is an added bonus.
10. Soft Skills
Last but not least, apart from these technical skills, the remote Java developer should also have some soft skills. With a remote work setup, communication and listening skills are a must. They should also be efficient in managing time working remotely. Lastly, they should be able to work in a team without physically being present with them. Now that you know the skillset to look forward to in your prospective remote Java developer, here are the different types of remote Java developers with different types of skills.
Types: Fresher and Experienced Remote Java Developers
Entry Level Java Developer
When hiring remote Java developers, the organization’s requirements make the candidate eligible or non-eligible. A basic yet solid understanding of the language and familiarity with classes, threads, and servlets would be enough for entry-level remote Java developers.
Intermediate Java Developer
For a more intermediate candidate with an experience of up to 2 years, all the skills mentioned above are necessary, along with the ability to write clean, readable Java code. They should understand J2EE, analysis, patterns of OOPs, and some of the web services based on Java.
Experienced Java Developer
Moving on, senior Java developers will not only possess the qualities mentioned above, but one of the advantages of having an experience of more than two years will also make them proficient in code optimisation. For example, they should be able to choose suitable algorithms to write with the minimum types of variables used.
You might need the best of the best for the roles requiring multiple algorithms with a higher number of exceptions, more data types, and platforms like Java Virtual Machine for memory management and safety. You may also need someone handy with design patterns and SQL (Structured Query Language).
