Java is a highly popular programming language that is widely used in the IT industry. Hiring Java developers is crucial for many organizations as Java is in high demand among employers, with more job listings on Indeed seeking Java skills than any other language. How to recruit Java developers is a question many companies face as they search for talented individuals to fill these roles. Java is a computing platform used for creating portable codes for desktop and server environments, making it easier to develop and share applications across platforms. Java is an object-oriented programming language that includes the unique feature of a just-in-time compiler.

Despite being a popular programming language, recruiters and companies often struggle to find skilled Java developers. In this article, we will share effective hiring techniques for finding expert Java developers. Whether you need to hire an individual developer, a team of developers for a new project, or augment your existing team, this article will help you find the most talented Java developers available.

What Does a Java Developer Do?

Java Developers are professionals who are responsible for managing the entire lifecycle of applications, from initial design to implementation and testing. They typically work for large enterprises that require complex applications.

In addition to their broader responsibilities, Java Developers perform a variety of day-to-day tasks. These include writing and debugging Java code, gathering the requirements needed to develop a software application, collaborating with colleagues to find the most efficient ways to complete tasks, and creating documentation to support implemented code.

To further elaborate, the role of a Java Developer can be broken down into various phases of an application’s lifecycle. During the design phase, Java Developers are responsible for developing a software application’s architecture and creating a detailed plan for the application’s development. In the implementation phase, they write the code required for the application to function. During the testing phase, Java Developers are responsible for testing the application’s functionality, detecting and fixing any bugs, and ensuring that it is ready for release.

Java Developers are critical members of the software development team, and their expertise is vital in ensuring that complex applications are built efficiently and effectively. They need to be able to work independently and as part of a team, as well as possess excellent communication skills, as they often collaborate with colleagues across multiple departments.

Skills To Look For In Junior Java Developers

It’s important to note that years of experience is not the only factor in determining a junior Java developer’s skill level. Some may have fewer years of experience but strong skills, while others may have more years of experience but weaker skills. You need a checklist to assess a candidate’s overall competency in Java development. Here’s a list of skills and knowledge you should look for when you recruit Java developer:

  • Writing clean and readable Java code
  • Strong knowledge of Java, Servlets, Servlet methods, and parameters
  • Understanding of Object-Oriented Programming (OOP) analysis and design patterns
  • Familiarity with Enterprise Java Beans (EJB)
  • Strong grasp of data structures and algorithms
  • Knowledge of Java-based web services
  • Practical knowledge of Relational databases, SQL, and ORM
  • Understanding of JVM and Memory management
  • Understanding of multithreading and synchronization

Skills To Look For In Senior Java Developers

To recruit Java developer on senior level, it’s recommended to look for someone with 3 to 6 years of experience in Java programming, who possesses the following skills and knowledge:

  • Writing optimized, readable, and clean Java code
  • Strong understanding of Object-Oriented Programming (OOP) concepts and deep knowledge of J2EE
  • Strong expertise in error handling and debugging techniques
  • Hands-on experience with query handling and the ability to write complex SQL queries
  • Good understanding of runtime and garbage collection to address memory-related problems

Additionally, the following points from the junior Java developer checklist are also important for a senior developer:

  • Knowledge of Java/J2EE
  • Familiarity with Enterprise Java Beans (EJB)
  • Strong grip on data structures and algorithms
  • Know-how of Java-based web services
  • Practical knowledge of Relational databases, SQL, and ORM
  • Concepts of JVM and Memory management
  • Understanding of multithreading and synchronization
  • Expertise in code optimization
  • Expertise in Servlet methods

It’s important to note that while years of experience can be a useful guideline, the skills and knowledge required for a senior Java developer may vary depending on the job requirements.

Recruit Java Developer With Qualifications

Classifying various job openings based on the candidates’ proficiency level is a typical practice. These levels include Junior, Mid, Senior, and Lead (Architect). The required skills, technical knowledge, and years of experience vary for each Java developer position. Let’s examine what qualifications are needed for each role.

When looking to recruit Java developers on junior level, companies typically look for 

  • Candidates with up to 2 years of experience in object-oriented programming with a focus on Java/J2EE.
  • Candidates should possess the ability to develop and improve software applications through coding and testing.

To be considered for Middle Java developer positions, most companies require at least 2 years of experience along with the following:

  • Middle Java developers are expected to be able to handle tasks independently, but know when to ask for help from their team members.
  • Applying relevant tech skills to deliver specifications, unit test scripts, and other requirements is also required.
  • However, these developers are not expected to have skills in predicting or planning for future software issues or inefficiencies.

If you’re looking to recruit Java developer on senior level, you should look for someone who can:

  • Solve more complex problems and perform faster and better than a mid-level developer.
  • Demonstrate extensive practical experience in Java development and be able to make relevant technological decisions in the project.
  • Possess excellent communication skills to convey important technical decisions to the team and project stakeholders.
  • Supervise and mentor junior developers, sharing their knowledge and expertise.
  • Take responsibility for the overall quality of the software and ensure that it meets the project’s objectives.
  • Stay up to date with the latest trends and developments in Java technology and use that knowledge to improve the project.

To hire a Java Architect, you should look for someone who can:

  • Ensure proper implementation of the software architecture and focus on its global development.
  • Possess excellent communication skills to provide technical leadership to the development team and translate client’s goals and needs into functional architecture.
  • Collaborate with other stakeholders to determine the project’s direction and ensure that the architecture meets their requirements.
  • Have experience in designing and implementing software architecture that is scalable, reliable, and secure.
  • Stay up to date with the latest trends and developments in software architecture and ensure that the team is also aware of them.
