Java isn't losing its place and will still be in favour in 2023. Learn more about Java developers and what you can expect based on their level of hands-on experience.

Java programmers' qualifications and what to expect

Java developers' ability to categorize themselves, which is affected by their years of experience and knowledge, directly impacts the skills they should have. Let's look at the skills Java app developers should have at each level of experience.

Technical skills


Trainees are an entry-level group with little to no experience in developing commercial projects. They have little or no practical experience but only theoretical knowledge. The mentor is always assigned to them. The mentor can assign small tasks to trainees, such as fixing minor or relatively easy bugs.

Skill set

  • Years of Experience: 0-1 year
  • Knowledge: Java core, JDBC. Proficiency in building RESTful interfaces with Java (REST/JSON) and SQL. Spring, Hibernate, and Web technologies (HTML CSS, JavaScript, JavaScript) will all be a plus.
  • English proficiency: Pre-intermediate or higher


Junior developer works on the project and completes simple tasks assigned by the client or manager. These are novice developers and may make mistakes. Their code must be reviewed. These specialists are great for simple tasks and fixing bugs.

Skill set

  • Years of Experience:1-1.5+ Years
  • Essential knowledge: Java Core (Core), Spring (Core MVC, Security and Data), JavaServer Pages (JSP), and servlets. Version-control systems (GitHub, GitLab), Hibernate, Jdbc/Hibernate. Gradle/Maven, Design Patterns, SOLID, RESTFull, Java 8+, Spring MVC, SQL (MySQL/PostgreSQL), JPA/Hibernate, Angular/React.
  • English proficiency: Intermediate and higher


Middle-level Java developers are often already self-sufficient. They don't require a mentor to supervise their work. They are also able to support less-experienced programmers. They can also help less experienced programmers by developing a project from scratch and delivering the product.

Skill set

  • 2+ years of experience
  • Essential knowledge: Java Core, Boot, MVC Security Data Cloud, Integration, Jdbc/Hibernate/JPA SQL (MySQL/PostgreSQL), Message Brokers Docker, Gradle/Maven Design Patterns, SOLID DDD TDD, Docker RESTFull Java 8+, Spring Framework/Spring Boot Hibernate JWT, Angular/React.
  • English proficiency: Intermediate and higher


This category of developers can build, manage, and fully deploy a project. They can mentor junior and intermediate developers. As the leader of the team, the senior Java developer should be. This is up to the individual developer's skill and initiative.

Skill set

  • 4+ Years of Experience
  • Must-have knowledge: Java Core, Patterns, Spring Framework/Spring Boot (Core, Boot, MVC, Security, Data, Big Data, Cloud, Integration), Jdbc/Hibernate/JPA, SQL (MySQL/PostgreSQL/Oracle), NoSQL, Message Brokers, Docker, AWS, Multithreading, Microservices, CI/CD, DDD, TDD, Docker, Java 8+. Excellent knowledge of Java 8+ and the JVM. Excellent knowledge of the architecture and design of OO software. Expertise in the development and deployment of large-scale systems.
  • English: Intermediate and Higher

Team leader

Senior specialists who aren't only skilled in code writing; team leaders are also senior developers. They create requirements for code styling, architecture, and code reviews and supervise their team members. They do not write code daily, but it is an occasional part of their job.

The impact of experience on developer's salaries

Years of experience and solid skills are extremely valuable. This is why the average salary for a junior Java developer will be significantly lower than that of a senior one. Let's look at the average salary for a Ukrainian programmer. A junior Java developer will earn $700 per month, while a senior Java developer will make $3,500.

We hope you now understand the differences between Java developers at different levels. This will help you determine the type of Java programmer required for your project. You can also check the average hourly rate of Java programmers in the table below. We offer an example of US Java developer rates.

Let's look at the various developer hiring models so you can choose the best suits your needs.

Types of Hiring Models

This section will look at different recruitment models and compare their benefits and disadvantages to help you choose the best one for your project. Let's see how much it costs to hire dedicated java developers, depending on your hiring model.

Freelance Developer

You can always hire Java programmers by looking for them on freelancing platforms. This hiring model is growing in popularity because of the influx of dedicated developers who are free to work in the IT industry. Fill out the required fields on freelance websites and begin your search.

The most trusted and popular freelance platform:

  • Upwork is a free website that has many skilled developers and places a strong emphasis on collaboration. They might be located nearby and are looking for a full-time position.
  • UpStack aims to improve remote developer teams worldwide by using dedicated freelance workers.
  • Guru provides employment and knowledge resources that cover various topics. Still, the section for freelance developers is the most popular.


Average hourly pay for a Java developer







The main advantage of this hiring method is: It drastically lowers the price. Because freelancers have a lower hourly rate than in-house professionals, you can save on expenses such as labour, taxes, and office upkeep.

The main drawback of this hiring method is: It is possible to meet unqualified specialists. Freelancers can disappear if something goes wrong. Due to the lack of oversight, freelancers can miss deadlines frequently, which increases project risk. This can lead to additional costs, and you will need to find a replacement.

In-house Development

In-house developers are full-time Java developers employed by your company. The person who works for your company can be a remote worker or works in the office. This model of recruitment is still very popular. You can hire a developer through job posting websites like Dice or social networks like LinkedIn. Or through a recruitment agency.


Java developer’s salaries per year













The main drawback of this hiring method is the high costs. The salary of a full-time employee is not enough to cover the additional costs. You must consider a paid vacation, leave requests and insurance to create the right working environment. This model is best if you have a Java developer who will be working as part of your team for a long time. If you only need a Java developer for a specific time or a specific Java-based project, you should consider another option.

Outsourcing Services

These concepts often need clarification, which is not surprising, considering they are very similar. In both hiring processes, an outside employee is hired, or employees are brought in from a third-party software development company. These models are different, and we'll look at them more closely. Depending on your project requirements, you will need to determine which model you require more.

The outsourcing model presumes that you outsource java development to an outsourcing company. If you require object-oriented development, this is also an option. Your outsourcing partner will manage the whole process and team and be responsible for the final result. There are many benefits to outsourcing for small and large businesses. According to Deloitte's model, the main benefits of outsourcing are cost reductions, flexibility, and a shorter project launch.


Outstaffing is another form of outsourcing where you apply to third-party development companies. You want to delegate only a little work, so hire offshore software developers to augment your team. This model is superior to outsourcing in that you can control the app development and management of your team. By having a clear view of the product's implementation, you can influence the pace and flow of the project. Let's look at the table that shows the rates for java development partners in the most sought-after destinations for outsourcing.

For good reasons, outsourcing and outstaffing have been rapidly gaining popularity in recent years. Both are business processes that allow companies to hire java developers at a lower development cost for a set time without sacrificing the quality of their work. Outstaffing is more appropriate for business owners who require more flexibility and control and are looking for a quick and trouble-free extension of their existing team. Outsourcing is better suited for clients who require a complete package of Java development services and want to delegate all development and project management to their chosen vendor.

Every business model has its pros and cons. But the important thing is to choose the best one for you and your project.

Final Thoughts

The performance of Java developers and programmers is key to the firm's growth. Technology advances make it more important to have skilled software engineers who can also understand older code.

Java is a popular global language, and many engineers only learn it to get a job in coding. Java development is a challenging task. Talented developers require a keen eye.
