Why You Need a Java Developer

This means that companies who use Java can save money by not having to develop separate versions of their software for different operating systems. Java is widely used across the industry for mobile apps, game development, enterprise applications, web, and desktop applications. Due to its popularity, there are many freelance Java developers of varying ability levels available, so make sure you know exactly what skills you need before hiring.

Do You Need a Junior or Senior Java Developer?

When it comes to Java development, there is a big difference between junior and senior developers. Junior developers are cheaper but tend to be less experienced. They are ideal for faster, less complicated tasks but have less knowledge of best practices.

Senior developers, on the other hand, are usually more experienced and have a better understanding of how to write efficient and maintainable code. Senior developers also have the skills to lead teams of less experienced developers.

Where to Hire Java Developers

Once you are clear on what type of developer you need it’s time to advertise. There are several ways to find the right person for your team.

Freelancer Sites

Post your freelance Java developer job opening on a site such as Upwork, or Freelancer.

Pros: Freelancer sites are great for finding short-term workers for a low price.

Cons: It’s harder to find quality long-term freelance Java developers, and you may experience international HR & legal complications.

Recruiters

Hire a recruiter to find candidates.

Pros: Recruiters are excellent at finding highly specialized developers.

Cons: Recruiters are less likely to find international candidates and can’t help with the problem of employee retention.

Outsource all aspects of building a remote development team to a third party like Terminal.

Pros: All aspects of hiring and employment can be left to the service. Vetting and sourcing candidates from across the globe, onboarding, payroll, HR support, and termination can all be handled by a team of professionals. This leaves you free to quickly get on with the job at hand, with the best developers on your team.

Cons: Some third-party management companies don’t offer a full range of services. Be sure to pick a full-service provider.
