If you are looking for 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 developers 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 developers? 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 gained its fair share of followers and a growing developer community. TIOBE Index shows that Scala’s popularity has increased five times since 2006.

Google trends show the growing interest in this programming language as well. Since August 2006, the overall interest in the technology has gone up three times.

Besides several spikes in the search volume back in 2004 and 2005, Google Trends shows that the interest in Scala developers has been growing steadily since 2007.

ITJobsWatch reports a similar situation in the interest in Scala developers in the UK. The number of job postings mentioning Scala on their website went up four times since 2012 [3].

Scala developers worldwide

As of 2018, there were nearly 22.3M software developers in the world [1]. Stack Overflow claims that approximately 4% of professional engineers use Scala [2]. If we search LinkedIn for a ‘Scala developer’, we will see that the top three locations by the number of Scala developers are the USA, India, and the UK.

However, the number of tech giants in these countries is high, as well as the competition for 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.

Number of Scala developers in Europe

Germany and France are leaders in Western Europe by the number of Scala engineers. As for Eastern Europe, Poland has over 2,900 professional Scala engineers. Ukraine has the second-largest Scala developers pool in CEE.

Demand for Scala developers worldwide

As of July 2019, LinkedIn.com lists over 66,600 Scala developer jobs available worldwide. Most of them are in the US (over 34,800 jobs), the European Union (12,800 posts), and the United Kingdom (4,500 positions). Another 1,700 Scala developers are needed in the Chinese IT market (according to Indeed.com). Nearly 90% of all jobs are open for the associate and entry-level engineers, with only 8% of all positions available for mid-senior Scala developers.

What is the average Scala developer salary? 

So how much do you pay a good Scala developer? Here’s a brief comparison of the average Scala developers’ salaries in the USA, Great Britain, and Europe.

Switzerland is the top-paying country in terms of Scala development, with the average annual salary of $92,000. A similar situation is in the UK, where Scala engineers earn around $90,000 a year. On the contrary, Eastern European countries offer much lower rates, for example, Poland offers an average annual payment of $55,000.

As seen from the graph above, Eastern Europe offers lower rates for Scala development. The average salary of a Scala developer is 30-25% lower compared to the US, which significantly reduces the cost of the project. Moreover, companies in this region have vast experience in outsourcing, quality services, and highly-skilled developers. Therefore, many companies choose to outsource Scala development or hire remote Scala developers to extend their local teams.

Success stories of outsourced Scala development

Outsourcing has many benefits: shared risks, reduced costs, a wider pool of experienced developers with the needed expertise, and much more. Therefore, many companies choose to outsource Scala development, and Eastern Europe is becoming a more and more popular destination. Eastern European software development providers have helped numerous businesses build secure, scalable, and efficient solutions using Scala.

We have selected several examples of successful Scala software development outsourcing. The featured companies are of different size and come from different industries. But they all successfully outsourced Scala development to Eastern Europe.

  1. MASMOVIL: Outsourced Scala development for telecom

MASMOVIL, a Spanish telecom provider, was growing fast and needed to scale up their software development team. They partnered with N-iX, an Eastern European IT company, to set up a dedicated development team in Ukraine. Together, the companies created an efficient and secure software solution for streamlining document management workflow. Scala was one of the key technologies used on the project, along with Java and JavaScript. As a result of successful collaboration, the company launched two products which enabled them to manage customer relationships more effectively.

  1. Knip: Scala development as a part of the Big Data solution for insurance

Knip, a Swiss-based digital insurance platform, partnered with a Polish software development company to work on their analytic application for the existing data warehouse [5]. Scala was one of the primary technologies on this project. An outsourcing vendor successfully developed a module that connects the warehouse to a mobile application.

  1. Mercanto: Outsourcing Scala, AI, and ML engineering

Mercanto is another company that benefited from hiring Scala developers in Eastern Europe. Together with its outsourcing partner, N-iX, Mercanto developed an AI-powered digital marketing platform. The solution uses machine learning algorithms and natural language processing to deliver personalized and relevant content to consumers, which increases conversion rate and boosts revenue. Since the solution had to process large volumes of data and needed to have good performance, Scala was chosen as the core technology.

  1. Adstream: Software product development for advertising

Adstream partnered an IT outsourcing partner from Poland to tap into their expertise in Scala, AWS, and Angular [6]. Scala engineers were directly involved in the development of core features, refactoring of the products, and migration to the cloud. Moreover, the outsourcing vendor helped Adstream to improve CI processes and reduce the number of faults within the system. 

  1. Telefónica Germany: Big Data platform for telecom built with Scala

Telefónica Germany needed to scale up the Big Data platform they already had [4]. An Eastern European outsourcing partner augmented the client's team with experienced software engineers, including Scala developers. Among several prototypes, the one that included Scala stood out. Once the solution was implemented, it allowed the company to process large amounts of unstructured data ten times faster than before.

  1. Gogo: Outsourced development of a Big Data platform used in aviation

Gogo is a global inflight internet provider that uses Data Science for predictive maintenance of its equipment installed on thousands of commercial and business aircraft. The company needed to expand its Data Science team and partnered with N-iX, and Eastern European software development provider.

N-iX helped Gogo build a team of over 30 software engineers with expertise in Big Data, Data Science, AI, Business Intelligence, and Cloud Solutions. Together with Gogo's in-house team, software developers at N-iX, including Scala engineers, developed a unified data platform in the cloud that helped their client significantly improve the performance of their equipment and the maintenance teams.

Afterword

Hiring Scala developers in a competitive market is a complicated and time-consuming process. Considering the deficit of Scala developers, finding a skilled engineer locally can be hard. That is why many companies decide to outsource Scala development. New tech talent pools, wide-ranging expertise, lower rates, and a wide choice of trusted outsourcing partners make more and more companies worldwide choose Eastern European vendors.
