J2EE Developer Duties and Responsibilities

No two J2EE developers are exactly alike, as specific skills vary from employer to employer. However, after analyzing online job postings, we identified several core duties and responsibilities common to the job:

Manage Java Application Life Cycles J2EE developers have key responsibilities throughout the entire life cycle of application development. They help draft software concepts and technical designs to implement high-performing and highly scalable applications. They formulate and implement solutions based on specific business requirements. J2EE developers write application code for Java programs and also manage the software's overall architecture.

Test and Maintain Software A major responsibility for J2EE developers is to test, implement, and maintain all application software on the J2EE platform. At times, they interact with other teams impacted by the application they're working on to coordinate testing.

Analyze and Debug Java Software Performing software analysis, programming, testing, and debugging is key duty of this role. J2EE developers troubleshoot issues and make system changes as needed. They also recommend changes to improve established Java application processes.

Write Software Documentation Software documentation is an important part of a J2EE developer's job. Their documents serve as a reference for future maintenance issues and upgrades. J2EE developers write and maintain technical documentation that covers logic, coding, testing, improvements, and corrections made to their specific software applications.

Lead Technical Collaboration J2EE developers often collaborate with other engineers and work with team members in product management and quality assurance departments. They do this to make sure their software has the features and benefits that clients want. J2EE developers also ensure that any software they create integrates with the proper business tools.


J2EE Developer Skills and Qualifications

J2EE developers should have a proven track record of handling software development from conception to release, including design, debugging, and documentation. A bachelor's degree along with three-plus years of technical experience with J2EE is typically sought out. Employers also seek the following skills:
  • Java programming - J2EE developers need highly proficient Java and JavaScript programming skills to build the enterprise-level applications they work on
  • ETL design - "extract, transform, load" (ETL) is a useful skill for J2EE developers because it allows them to perform data mapping, configuration, and management of their enterprise applications
  • Agile development - J2EE developers need to be well-versed in test-driven development to make their projects successful
  • Writing skills - writing detailed design documents for new application features is a key task for J2EE developers
  • Experience with enterprise JavaBeans (EJB) - this server-side software component manages the business logic of an application and simplifies development
  • Communication skills - J2EE developers need interpersonal skills to lead the software architecture discussions and technical dialogue they have with colleagues
  • Problem-solving skills - analytical skills and conflict resolution are used by J2EE developers to complete assignments under pressure and build needed consensus in an organization

J2EE Developer Education and Training

It's common for J2EE developers to have a bachelor's degree in computer science, software engineering, or a related field. Additionally, employers prefer candidates with a technical background who have strong experience in several of the platform's technologies, such as Java, AngularJS, Spring, and Node.js and REST application programming interfaces.

J2EE Developer Salary and Outlook

According to the Bureau of Labor Statistics (BLS), the median annual salary for software developers like J2EE developers is $101,790. The highest 10 percent of earners make more than $160,100, while the lowest 10 percent earn less than $59,870. The BLS has predicted a job growth rate of 31 percent through 2026, which is much faster than average for all occupations.
