4 Types Of Java Developers

Image describing the different levels of Java Developers

The level of the Java software’s complexity and scope of work involved calls for different levels of competency. It’s important to know the complexity of the work so you can hire the right type of Java developer and maximize the pay you offer.

For example, say you hire a Senior Java developer but the scope of the work can be done by a Junior Java developer, you’ll be paying too much for the expertise you don’t necessarily need. For Java developers, there are 4 types you can choose from:

  • Junior Java developer
  • Mid-level Java developer
  • Senior Java developer
  • Lead (Architect)

I. Junior Java Developer Qualifications

Junior Java developers ideally have 2 years of experience with OOP or object-oriented programming on J2EE or Java. They know how to develop or improve Java apps by coding and testing. When considering Junior Java developers, you should look for the following skills:

  • Java programming language
  • CSS and HTML
  • SQL and ORM
  • JVM
  • API
  • JavaScript
  • Web Services
  • Memory Management

II. Mid-level Java Developer Qualifications

A mid-level Java developer ideally has more than 2 years of experience. They should be able to work on tasks with minimal to zero supervision. Upon reaching this rank, they should have exceptional mastery of the skills required from Junior Java developers. They should be able to deliver specifications and test scripts. In addition to their skill set, they should have experience working with:

  • Spring
  • REST and JSON
  • Hibernate
  • TomCat
  • Maven
  • Unit testing

III. Senior Java Developer Specifications

As for Senior Java developers, apart from the mastery of the skills attained by mid-Java developers, they should be able to solve complex problems easier than mid developers can. Ideally, they should already have extensive experience in Java software development and can already make technological decisions in the Java projects they are handling.

They should also have excellent communication and leadership skills since they will work closely with stakeholders, conveying vital technical decisions needed for the project and guiding their Java development team members. At this rank, they can supervise the full project development phase and mentor Junior Java developers on their way to skill mastery.

For Senior Java developers, you need to be on the lookout for skills like:

  • Mastery of Spring MVC and JSF
  • Mastery in the Principles of Solid
  • Integration and functional testing
  • Mastery of patterns of development
  • Mastery of the agile development methodology
  • Exceptional knowledge of data structures and algorithms
  • Years of experience with multithreading and synchronization

IV. Java Lead/Java Architect Qualifications

The major responsibility of a Java Lead or a Java Architect is to ensure that the client’s vision is translated into functional Java architecture. For this, they should have the skills that assure proper implementation and global development of the Java software project. They should also have excellent communication skills especially since they have to communicate closely with the client to ensure each functionality and the design of the project goes in line with what they expect.

Just like a Senior Java developer, a Java Architect should also possess exceptional communication skills plus:

  • Mastery of architectural patterns
  • Mastery of clustering architecture skills
  • Mastery in service-oriented architecture
  • Extensive experience with legacy platform integration skills
  • Can create scalable, high-performance, and maintainable Java applications

If you still can’t determine the exact type of Java developer or the tech skills you would require for your Java candidates, here is a list of the general skills each Java developer should have regardless of their rank and years of experience.

  • ORM (object-related mapping)
  • OOP (object-oriented programming)
  • IoC (inversion of control)
  • Java tools (Gradle and Maven)
  • Java application containers (JBoss and Jetty)
  • HTML, SQL, JavaScript, Python, C#, PHP
  • JSON and XML
  • Oracle
  • Can design, develop, implement, and test Java software in at least one framework (TomCat, Hibernate, Spring, or JavaEE)
  • Can ensure full compliance with the Java solution’s design and specs
  • Can ensure client requirements are translated into the Java-based solution
  • Can debug and solve basic technical problems
  • Collaborate well with team members and recommend ideas for existing Java apps or solutions

No matter the level of expertise, an excellent Java developer should have some familiarity and experience that allows them to easily explain the following:

  • Basic data types and wrapper classes
  • Interfaces, inner classes, and abstract classes
  • Different levels of class protection and member variable
  • Collection framework

While not necessary, you can also consider it “nice to have skills” for Java coders like AWS, Google Cloud, and microservices. For soft skills, an excellent Java developer should at least have:

  • Good problem-solving skills
  • Analytical mindset
  • Strong attention to detail
  • Ability to implement quick adjustments in a testing environment
  • Ability to work productively with the Java team they are part of
  • Good English communication skills

How Much Should You Pay A Java Developer?

There are a few factors to consider when deciding how much to offer a Java developer candidate. Two factors affect it the most: location and expertise. This is not a conclusive pricing list but just ballpark pricing that’ll get top Java developers interested in your offer.

  • United States: Junior-$54,000/year, Mid-level-$160,000/year, Senior-$93,000/year
  • Canada: Junior-$30,000/year, Mid-level-$84,507/year, Senior-$165,000/year
  • United Kingdom: Junior-$19,673/year, Mid-level-$69,454/year, Senior-$145,510/year
  • China: Junior-$11,039/year, Mid-level-$19,542/year, Senior-$52,511/year
  • India: Junior-$2,643/year, Mid-level-$6,385/year, Senior-$14,447/year

Right off the bat, you’ll see the striking difference between the rates of Java programmers from the United States from those living in India. Keep in mind the rates don’t necessarily affect the quality of the Java software. You can still find the best Java developers in India with the right screening process and conversely, not every Java software engineer in the US produces exceptional results.

However, with the stark difference in pricing, many businesses opt to outsource the software development or work with remote nearshore or offshore Java programmers. The quality of the Java software might be in question, but by working with us at Aloa, you’ll take advantage of fully-vetted Java developers so no matter where they’re from, you’re assured to get the Java software you expect when you need it.

3 Hiring Models To Choose From

When hiring a Java developer, there are several work formats you can consider.

A. In-house Java Developer

As the name suggests, these are the Java programmers that are willing to work on-premise. This allows for easy communication and feedback when decisions need to be made or ideas need to be generated.

The downside is, that this will require you to spend on resources to accommodate the Java developer working in the office. In most cases, they would be working on a full-time basis, this means they are hired as employees that get the same benefits as other full-time employees working with you in other departments.

B. Remote Java Developer (Nearshore Or Offshore)

These Java programmers are given the liberty to choose where they want to work. Since they don’t report on-premise, you won’t need to provide them the equipment and space you’d otherwise need to give when they work in-house.

This also allows you to take advantage of Java experts around the world. On the flip side, since they’ll be working remotely, you’ll have to work on providing a communication tool to be kept in the loop and get quick feedback when needed.

C. Outsourcing The Entire Java Development

Outsourcing the whole Java project means you hire Java developers from an outsourcing company like ours at Aloa. The great thing about this arrangement is that you won’t need to constantly monitor the progress of the project giving you more time to focus on other important matters about the business. We take care of the whole project from design to testing and initiate providing you the progress ourselves.

If you choose to work with us at Aloa, you’ll be able to leverage our fully-customizable project management platform. This allows you to have full transparency on the progress of your project without having to ask us first. We also do constant re-evaluations to ensure our Java developers are constantly up-to-date with the latest tech updates and development best practices which will translate to the quality of their output.

Now that we’ve covered the types of Java developers, some suggested developer salary rates, and hiring options you can choose from, let’s put everything together in a step-by-step hiring process you can follow to get excellent Java developers.

5. Upwork

Upwork is a freelancing site for all types of jobs including Java developers. While Upwork can add some references to past clients for the Java developer you’re interested in, you can’t vouch for their expertise completely because Upwork doesn’t have a thorough vetting process in place.

6. Dice

Dice is a job hiring platform specifically created for tech candidates like Java developers. Like Upwork, Dice doesn’t have a strong vetting process in place, so you’ll have to do extra work in ensuring you’ll be working with a qualified candidate.

7. LinkedIn

While not a job listing platform, LinkedIn is a social media platform for professionals. You can search for Java developers and you’ll be provided with a full profile including work experience and certifications received by the candidate. Still, there’s no vetting process in place so the screening process will take much more effort.

8. Freelancer

If you’re looking to hire remote freelance Java developers, this platform is one place to consider. Their large network of freelancers affords you access to hundreds of tech talents. However, Freelancer doesn’t have a rigorous vetting process in place and a project management platform you can leverage.

9. AngelList

AngelList is home to 8 million tech talents. You can also explore this platform if you haven’t found the perfect candidate yet. They offer an optional vetting process and highlight new top-performing talents every 2 weeks for you to choose from.

10. Guru

Like Upwork, Guru is home to all kinds of freelancers. The downside is the same as well, there’s no standard vetting process in place so only a well-crafted job description will help you narrow down your search to only the qualified candidates you can consider.

5 Steps In Hiring An Excellent Java Developer

Following this process with the hiring elements discussed above in mind, shortly, you’ll be able to find the right candidates to work on the project you’re looking to build.

Step 1: Define The Java Project Scope And Hiring Essentials

The first step in hiring an excellent Java developer is to identify what your project is for and who its target users are. By knowing the answers to these two questions, it’ll be easier for you to define what functionality you want to include in your Java software. This way, you can gauge the complexity of the project and identify the right type of Java programmer to do the job.

Additionally, identifying your Java project’s goals and target audience will help in identifying Java app development requirements. At this point, you should be able to map out the software objectives, features, functionality, user requirements, conversion strategies, budget, and timeframes.

You should also be able to define where your Java project falls under. It can be:

  • Java web application development
  • Custom Java application development
  • Java game development
  • Java app maintenance
  • Java app update and migration
  • Enhancing the Java legacy system
  • Java product development

Step 2: Create A Detailed Job Description For Java Developer Candidates

This detailed job description can either be shown on Java job posting platforms or as a guide when reaching out to custom software development companies.

The detailed Java job description should include:

  • A brief intro to the Java project
  • Brief background of the organization and what the Java project will be used for
  • Responsibilities and roles
  • Required skills and “nice-to-have” skills (tech skills and soft skills)
  • Preferred work arrangements
  • Salary and benefits offer
  • Contact information

Filling up the parts listed will be much easier when you clearly accomplish the first step of defining the Java project scope. Once you know the scope of the project, you’ll know what type of Java developer to hire and what responsibilities and skills you can add to the requirements.

Step 3: Find The Java Developer

This involves going to the preferred Java developer sources. You can either post on Java hiring platforms, freelancing platforms, or on Java development outsourcing companies like us at Aloa.

By choosing us, you won’t have to worry about verifying the declared skill set of the candidates. Our thorough vetting process includes steps that test out the expertise and knowledge level of our candidates. We also check for references to ensure they are part of the project they claim to be or have the knowledge they declared to have.

Step 4: Review And Interview Shortlisted Java Developer Candidates

At this point, you can narrow down your list further by evaluating the expertise of the candidates by letting them undergo online skill tests if they haven’t yet and followed by an interview.

The interview won’t only confirm their skill set, but it’ll also give you a glimpse of how they communicate. Communication is vital to ensure the project goes accurately as expected by the client. Without clear communication, the chances of missing out on important design and functionality are higher.

Some of the questions you can ask are:

  • What is an abstraction in Java?
  • What are the Java access specifiers?
  • How does a Java thread work?
  • How are constructors different from methods?
  • What is Java’s final keyword?
  • What would you choose between REST and SOAP, and why?
  • What is the Spring MVC framework?
  • What are JSON objects>
  • How will you manage web services API versioning?
  • What are JSP implicit objects
  • What are JSP’s benefits?

After confirming their expertise, you can give added insight on what the job is about, the work, and salary arrangements to Java candidates with good potential of getting hired.

Step 5: Hire And Start Onboarding

After knowing each candidate deeper, you’ll now be able to distinguish the best one from the pack. As an etiquette, you can also inform others that a candidate was already hired so they won’t wait for anything.

After informing the chosen candidate that they are hired, you can now move to the onboarding process. This involves orienting them with the company's background and culture. It also includes introducing them to other Java team members and outlining the final roles and responsibilities they will handle within the team. You can also introduce organization standards and practices they need to observe.

Confirm your work arrangements and agree on the pay rate. Lastly, brief them on communication arrangements and meeting schedules.


Finding an excellent Java developer is a challenging task but not an impossible feat. However, by following the 5-step process above and considering the suggested criteria for each type of Java developer, you’ll find the right candidate knocking in your inboxes in no time, waiting to get hired.

To make the process faster and more efficient, choosing talent sources that have a strict pre-screening phase in place will make the hiring process a breeze for you. You’ll rest assured that while you don’t monitor their progress 24/7, the project will run as smoothly and reach your expectations once the building process is complete.
