Scala is a general-purpose, high-level, multi-paradigm programming language. It is a pure object-oriented programming language that also provides support to the functional programming approach. Scala programs can convert to bytecodes and can run on the JVM. Scala stands for Scalable language and also provides JavaScript runtimes. The programming language is highly influenced by Java and some other programming languages like Lisp, Haskell, and many more. Scala provides language interoperability with Java so that libraries written in either language may be referred directly to Scala or Java code.

Unlike Java, Scala possesses several features of functional programming languages like Scheme, Standard ML, and Haskell, for currying, immutability, lazy evaluation, and pattern matching. It also has an advanced type system supporting algebraic data types, covariance, and contravariance, optional parameters, and other support facilities. Scala makes no distinction between statements and expressions. In simple terms, Scala language is designed to grow with the demands of its user, from writing small scripts to building a massive system for data processing. Scala language can be extensively used in data processing, distributed computing, and web development. It powers the data engineering infrastructure of several enterprises.

Types of Scala Jobs

According to some professionals, Scala is one of the most difficult programming languages to learn. But learning this programming language would provide an array of job opportunities in the top organizations, and in some of the most eminent positions. But this also makes it quite difficult for companies to find candidates who can efficiently utilize this technology and enable the organization to enhance its capabilities.

Enterprises mostly hire Scala developers who are highly skilled in designing, creating, and maintaining Scala-based applications. They are also responsible for producing code in line with application specs, performing software analysis, and collaborating with the software development team to verify application designs. Companies mostly hire Scala developers who can help them in creating highly scalable applications, and performing regular updates. In a nutshell, Scala professionals are some of the most well-paid professionals as it supports a wide range of development solutions. Starting from applications to machine learning, to webpages and Android development, Scala programming language can get almost any job done.

Besides becoming a Scala developer, professionals can also choose to become software developers, application developers, IT consultants, and software engineers, by learning the Scala language. Top companies like LinkedIn, Twitter, Netflix, Sony, Apple, AT&T, and Airbnb, to name a few use Scala programming languages for their daily operations. Hence, Scala professionals can get hired by some of the top tech companies after learning this language.

Salary of Scala Professionals

According to reports, Scala developers take up a hefty amount annually. Professionals have claimed that scala developers get around US$135,900 per year. Entry-level positions start at US$117,000 per year while most experienced workers make up to US$175,500 per year. The average salary of a software engineer is about US$111,162, and that of a software developer is around US$105,000. Various roles offer various payscales, but it is important for Scala aspirants to keep upskilling themselves to gain that stature that would pay even more handsomely.

Required Education

To acquire a job in Scala, professionals have to become an expert in an object-oriented and high-level language. They have to learn how to design, develop, and test technical solutions and components for enterprises and build applications on the cloud. Scala aspirants would also have to be proficient in other programming languages like Java, Python, and JavaScript. They would also have to study Spark, Hadoop, and MapReduce. Scala professionals must have experience working with ETL architecture as well as public cloud platforms such as AWS. They must also acquire a robust understanding of software development methodologies. In addition to these technical skills, Scala developers and engineers must have accurate communication and analytical skills.

Besides having thousands of colleges and universities offering courses on Scala, there are also offline courses offered by Udemy, Coursera, and Pluralsight, which are some of the best online course providers in the world.

Experience

Several employers look for candidates with professional experience. They can showcase their work experience through resumes, cover letters, and portfolios. The position in which they are hired depends on their education level, and professionals may have different experiences with fieldwork. Graduates with a master's degree might be subjected to enhanced financial compensation. Undergraduates can pursue internship opportunities while they pursue their degrees. Several internships allow students to find full-time employment at their companies. Professionals can focus on gaining more experience through programs and craft their resumes according to the requirements of their dream companies.

Skills

As obvious as it is, professionals need to possess proficiency in Scala, they should possess knowledge of other object-oriented programming languages such as Java and Python and experience building software solutions. They should have technical skills, and the knowledge of object-oriented programming concepts and patterns is also mandatory. They should acquire basic knowledge of Spark, Hadoop, and MapReduce, and experience working with ETL architecture and cloud platforms like AWS. A solid understanding of software development methodologies and, obviously, strong communication skills.
