If you are looking to hire Scala developers, you have probably considered the benefits of this programming language and, maybe, even chosen it for your project. Indeed, Scala allows achieving impressive scalability. Its complexity promotes better coding practices, and it is a great technology for enterprise-level solutions.
However, hiring Scala engineers is not easy, especially in such hot markets as the USA, the UK, and most of Western Europe. A lot of companies that have difficulty hiring Scala programmers locally explore other talent pools, such as India and Eastern Europe. So where to find the best Scala experts? Is it worth outsourcing Scala development? And how much would it cost?
Interest in Scala as a programming language
Scala was first introduced to the general public in 2004, with the second version (2.0) released two years later. Since then, Scala has got its fair share of followers and a growing developer community. The TIOBE Index shows that Scala’s popularity has increased five times since 2006.
Global demand for Scala developers
Excluding several spikes in the search volume back in 2004 and 2005, Google Trends show that the interest in Scala specialists emerged in 2007 and was growing ever since. ITJobsWatch reports a similar situation in the interest in Scala engineers in the UK. The number of job postings mentioning Scala on their website went up four times since 2012 .
Demand for Scala developers worldwide
As of April 2022, LinkedIn.com lists over 60,000 Scala jobs available worldwide. Most of them are in the US (over 27,300 jobs), the European Union (15,300 posts), and the United Kingdom (almost 2,500 positions). Another 4,700 Scala developers are needed on the Chinese IT market (according to Indeed.com). Nearly 43% of all jobs are open for the mid-level engineers, and another 25.4% of all positions available are listed for senior Scala specialists.
The number of Scala engineers worldwide
As of 2020, there were nearly 28M software developers in the world. Stack Overflow claims that approximately 4% of professional engineers use Scala . If we search LinkedIn for a ‘Scala developer’, we will see that the top three locations by the number of Scala experts are the USA, India, the UK, and France.
However, the number of tech giants in these countries is high, as well as the competition for the tech talent. Companies can wait for months to hire a single Scala developer for their project.
On the other hand, the European tech talent pool is smaller, compared to the USA, yet the competition there is lower.
France and Germany are the leaders in Western Europe by the number of Scala engineers. As for Eastern Europe, Poland has over 3,500 professional Scala engineers. Ukraine has the second-largest Scala pool in CEE.
What is the average Scala developer salary?
So how much do you pay a good Scala expert? Here’s a brief comparison of the average Scala developers’ salaries in the USA, Great Britain, and Europe.
The US and Switzerland are the top-paying countries in terms of Scala development, with the average annual salary of $130,000+. A similar situation is in the UK, where Scala engineers earn around $125,000 a year. On the contrary, Eastern European countries offer much lower rates, for example, Poland offers an average annual payment of $60,000.
As seen from the graph above, Eastern Europe offers lower rates for Scala development. The average Scala developer salary is 25-40% lower compared to the US, which significantly reduces the cost of the project. Moreover, companies in this region have vast experience in outsourcing, top quality of services, and highly-skilled developers. Therefore, many companies choose to outsource Scala development or hire Scala developers to extend their local teams.
