Java Web Developer Duties and Responsibilities
Java web developers' duties depend on their work environment, but most share several core responsibilities:
Build Server-side Logic and Architecture In general, Java web developers design and code server-side elements of a website or application, including the logic and architecture that support user-facing activities. Java developers work with other web programmers to determine functional needs and how to deliver a high level of reliability and speed to the end user.
Optimize Server-side Code Speed Java web developers also constantly try to improve the speed of delivery and data handling by improving their back-end code. This part of the job requires the developer to keep up with developments in the coding language, along with extensions and improvements that provide greater responsiveness and flexibility to speed up common requests and frequently-repeated blocks of code.
Implement Data and Information Security Java web developers ensure that their data and that of their users are secure at all times by integrating the latest data and information security protocols into their code. In many cases, this includes performing periodic audits and updates of security protocols to prevent intrusion or data loss and to ensure that information submitted by users is correctly handled and encrypted while they use the site or application.
Manage Back-end Data Storage and Handling Another major duty of the Java web developer is designing data handling, storage, and processing logic on the website's back end. This requires extensive familiarity with data structure, along with some experience with relational database systems such as SQL. The Java web developer also needs to have an excellent grasp on how the server handles data requests and often needs to write code to ensure that queries occur in the proper order.
Maintain Code Libraries and Documentation Finally, Java web developers support future development efforts and cross-functionality by maintaining code libraries and detailed documentation. These code libraries can help save time and effort while programming future versions or similar websites or applications since they can provide a solution or a starting point for another developer on the project. Documentation also helps with this, particularly since Java is an open-source language.
Java Web Developer Skills and QualificationsJava web developers program server-side environments and elements for websites and applications. Most workers in this role have at least a bachelor's degree and the following skills:
- Programming - excellent programming skills are a necessity in this role; Java developers should be able to write clean, responsive, and scalable code to make websites and applications function
- Database - Java web developers rely on their familiarity with relational databases, so experience with data management and organization is helpful
- Troubleshooting - debugging websites is also important in this role, so Java web developers should have effective troubleshooting skills and be able to track down bugs through close examination and testing
- Team coordination - Java web developers need to work with teams of programmers, so effective collaboration and coordination are vital, especially to ensure that back-end and front-end elements work together seamlessly
- Problem-solving - Java developers often need to find answers and solutions to coding issues and software problems
- Communication - effective written and verbal communication are necessary, both to interact with team members and to prepare usable documentation throughout the development cycle
Java Web Developer Education and TrainingJava web developers typically have at least a bachelor's degree, often in computer science, engineering, or a similar field. More importantly, Java web developers need to have a strong foundation in programming principles and solutions. There are many opportunities for on-the-job training in this role, especially as Java web developers frequently need to seek out answers to software and coding issues and examine documentation and community resources to solve code problems.
Java Web Developer Salary and OutlookJava web developer salaries can vary depending on the region and organization. The Bureau of Labor Statistics (BLS) estimates that software developers for applications, including Java web developers, earned a median annual salary of $107,790 as of May 2017. The lowest-paid software developers earned less than $59,870 per year, while the highest-paid 10 percent of workers in this role earned more than $160,100. Employment in this field is expected to grow at a much faster-than-average rate between 2016 and 2026, with the BLS projecting 24 percent employment growth.
