Scala is actively used in the implementation of projects of Siemens, LinkedIn, Novell, Foursquare, Twitter, and Huawei. However, it is not widespread. This is due to the rather complex implementation of the object-oriented language paradigms. At the same time, its compatibility with Java libraries is a significant advantage.
There are not many job openings on the technical market, or job seekers specializing in this programming language. This situation can be explained by the peculiarities and complexity of the language, which is optimal for implementing large-scale projects. However, Scala is gaining momentum and, in the foreseeable future, the demand for programmers of this specialization is likely to increase significantly.
It’s optimal to entrust a Scala Developer with creating server and enterprise applications, because, the more complex the task, the easier it can be handled using this language.
A Scala programmer should be fluent in IntelliJ IDEA, SBT build tool, Gradle, and have excellent skills in working with Java, algorithms, and data structures. In addition, they need personal qualities such as communication skills, perseverance, responsibility, curiosity, and flexible thinking.
For those who have decided to study Scala on their own, a training course of the Scala developer Martin Odersky, posted on the Coursera service, would be a good place to start. The obtained certificate and experience with Java can be a significant advantage for the applicant and a positive signal to the employer.
