How much does it cost to hire an entry-level Java developer?
The next important step in hiring an entry-level Java developer is to define the approximate recruitment costs. The table below provides the average annual salary of a Java developer across five continents, based on location and seniority level.
Moreover, based on Indeed research, the average Java programmer salary in the US is $96,143, ranging from $81,377 to $108,416 per year, depending on the candidate’s qualification level, educational background, and experience.
At the same time, Switzerland holds the record for Europe’s highest Java developer salary, which reaches $95,093 per year. Israel comes second with $85,793, while Denmark has a top 3 podium finish with $76,077.
Without previous working experience in IT, it’s almost impossible for an entry-level Java engineer to reach the highest salary level.
However, even a Java coder with less experience can receive good compensation. According to PayScale, most entry-level Java developer salaries range between $37,382-$89,618. The sum varies greatly depending on the country. The highest rate is in Australia and USA, while the most cost-effective regions are Eastern Europe and India.
A certain set of competencies can increase the final payment for the job:
- Full understanding of Java programming language;
- A course degree in computer science or related technical field;
- Experience with Java frameworks, data structures, databases, algorithms, and more.
The Java developer salaries depend on the following factors:
Senior and architect developers earn more as they bring more value to a company and, as a result, more revenue. On the contrary, an entry-level or a junior developer needs more guidance from the team members and, thus, is likely to be less effective.
Location is the key player in determining the salary of a Java programmer. The US remains one of the most expensive markets for hiring Java developers. Though, if you consider reducing the cost of your project, you should think more about outsourcing talents with the same expertise but at a lower rate, such as Ukraine, Poland, Albania, Serbia, Romania, etc.
The skillset of a candidate has a huge impact on the salary. Lack of expertise in Apache Struts, Eclipse Java IDE, J2EE, significantly affects an entry-level Java developer's salary.

Best tactics for a winning recruitment strategy
The whole hiring process is divided into several stages – from posting job descriptions to sending job offers. Thus, if you’re looking for an entry-level Java engineer for a Java software development project, you’ll need to get maximum value from the time and cost of hiring. Here is what needs to be done:
Specify the requirements & customize your job description
Start hunting Java freshers by clearly defining what you need to get your project through to the finish line. A concise job description that lists specific tasks, skills, project duration and scope of work is a must-do to attract the right candidates to your organization. Make sure to:
- Prepare a detailed job description based on your project requirements;
- Determine the tech skills required for our project;
- Decide what level of competency is enough for you.
Advertise your vacancy
You’re all set to post your vacant position on different job boards like Indeed, Glassdoor, LinkedIn or Crunchboard and Java community platforms. Don’t promise the moon to get your entry-level Java engineers hooked. Instead be realistic and authentic. Plus, make as many announcements that a job is available as possible, to increase the chances of finding the right fit.
Make the right decision
After you’re done with job posting and advertising, your next step is to study each of the resumes you’ve received in your email. Your task is to decide what entry-level Java candidate is more suitable for your project. Read carefully each point - education, certification, experience, skills and underline those points that are unclear and need to be discussed in detail.
Conduct one-on-one interviews
Is anyone shortlisted in your mind? Conducting one-on-one interviews with selected candidates allows you to identify their hard and soft skills and understand what kind of person the candidate is. During an interview, it’s crucial to evaluate the candidate. How to do it? Ask technical and insightful questions and put the applicant’s skills to the test. Ask them to write a little code or a simple program. Identify their soft skills by suggesting some possible situations they may face while working on the project and ask them what they’ll do. This will help you find out how communicative and cooperative your prospects might be, to see how they can align with your project. Keep in mind that the quality is paramount here.
Additionally, it’s worth noting that If you’d like to skip the screening and interviewing processes of the potential candidates, you should consider ordering outsourcing services and trust it to the company’s recruiters.
Weigh up the pros and cons of all the candidates
Whether it’s important to stick to timeframes, don’t rush to hire the first prospect who impresses you. Take your time and ensure you find the right candidate based on the selection criteria. Come back to the job description and look through it again. Consult other recruiters in the field, if you have troubles judging the candidate’s abilities on your own. And, most importantly, don’t forget to keep your hiring budget in line. Know the average annual salary and hourly pay rates of entry-level Java developers and be ready to pay accordingly.
Top 13 entry-level interview questions
