3 ways to hire Java Developer in your company

Finding a qualified Java Developer can be more complicated than you think. It’s usually not enough to add a job listing to the “Careers” page on a company’s website and wait for applications. So, what can you do to have a Java Developer in your team? Here are five tips that can help:

1. Write a job offer tailored to your candidate’s needs

A good job ad is your business card and often the first contact with a candidate. Therefore, you should write it in a way that will interest him and encourage him to work in your team. How to do it? First of all, respect your candidate’s time. Software developers don’t want to waste their time and expect to find all specific information in the ad. You should include information about salary, tech stack, possible forms of cooperation, equipment, used tools, project, team, and everything important from the candidate’s perspective. You can ask programmers from your team what information is crucial for them or publish an ad on the job board for the IT industry that has tailored ads for the candidate.

2. Search for developers in the right places

​​Contrary to what you may think, LinkedIn may not be the best place to find an IT professional. If you are concerned about finding a qualified developer, you need to find other sources as well. These can be Java-related topic forums, but also GitHub or StackOverflow. In these services, you will find profiles of software developers, which can give you more information than their LinkedIn or even CV. How is this possible? For example, on GitHub, developers like to share their projects, so you will assess the quality of their work and whether they are involved in the Java community. You can also add job offers on specific groups on Facebook. Some of the most popular ones in Poland are: IT Jobs in Poland, Praca zdalna IT, and Praca szuka specjalistów z branży IT.

You can choose another form, such as staff augmentation, managed team or body leasing.
