Guide To Hiring Great Freelance Scala Developers
There are multiple challenges to hiring Scala developers. First, it is a high-demand field. The Bureau of Labor Statistics anticipates an astonishing 18% increase in employment for software developers between 2023 and 2033. While there are multiple programming languages, Scala has proven itself useful for some very specific tasks, such as working with big data.“Scala is the most popular FP language, and it has some of the best resources for practicing and learning FP. It’s also one of the most Python-like languages I’ve used. There’s no doubt in my mind that it will continue to be in demand.” — Alexandru Nedelcu
This raises another obstacle to finding Scala developers: it is a highly niche field. There are many more developers proficient in Python or Java than Scala, and the smaller talent pool means a more competitive hiring process. Additionally, it may be difficult to find programmers with the desired experience levels in this specific language.
This is especially problematic because of the complexity of Scala. It is generally considered more complex than other, more mainstream, languages. However, the growth of big data demands its functional and object-oriented programming. Scala engineers can solve complex programming problems and build data-oriented applications.
The high demand and limited number of programmers also raise the cost of hiring Scala developers. According to BLS data, the average May 2023 salary for a software developer was $132,270. Scala developers often command even higher wages. As a result, many employers must consider alternatives to traditional staff positions, such as hiring freelance Scala programmers.
While there are challenges to hiring Scala developers, you can overcome them. Here we look at some of the reasons you may want to hire a freelance Scala developer, how to create a solid job description and hiring plan, and tips for screening candidates so you find one who is a great fit for your organization.
