Ruby / Rails

Rails is closely related to Ruby, but the difference between them is significant: Ruby is a programming language, and Rails is a framework created for Ruby.

One of the fastest-growing programming languages, Ruby is characterized not only by multithreading and open - source code, but also by the ability to create cross-platform apps, typification, garbage collection, and ease of writing and reading syntax. Its use in IT technologies is inextricably linked to the framework that can significantly simplify the process of creating a modern web application, called Rails. Shopify, GitHub, Airbnb, SoundCloud, Zendesk, Twitter, and Cookpad were created using Ruby on Rails (abbreviated as RoR). The distinctive feature of this framework is that you can extend it by contributing your own code, therefore adjusting it to the project’s requirements.

Working with Ruby allows you to save time and reduce code volume without losing functionality. It provides a set of powerful tools in the form of dynamic typification, which significantly speeds up the programming process. The Ruby / Rails combination is optimal for the large project development process at the testing stage, as it contains a base of ready-made solutions for both integration tests and unit tests.

Ruby is one of the top ten most popular programming languages among developers ( and one of the top ten languages that developers would like to learn) . However, it's not as popular as JavaScript, Java, Python, or PHP. The same is true about the Ruby on Rails framework in comparison with other widely used frameworks.

You can entrust a Ruby on Rails developer to:

  • create web applications 
  • improve the functionality of online stores 
  • automate tests automation 
  • perform a database architecture project 
  • write structured code 
  • debug and perform further maintenance of software.

Such specialists are in demand in IT companies, banking, E-commerce, and advertising agencies.

Ruby programmers must know English (Intermediate level or higher) and have at least 2 years of programming experience . They should also be proficient in MySQL, JSP, UnitTest, Grails, HTML, CSS, PostgreSQL, and technical documentation development skills. Many employers also want an employee to know an additional programming language: PHP, Java, C++, or JavaScript. Personal qualities are also important: a creative approach to tasks, communication skills, and ability to work in multitasking mode and emergency mode.


We have collected answers to the most common questions for companies looking for Ruby on Rails developers. If you still have any questions, our experienced INDIGO Tech Recruiters will be happy to answer them.

1. What are the job responsibilities of a Ruby programmer?

Developer responsibilities include: · development using Ruby tools with mandatory planning of the technical specification · testing and debugging all created modules and their relationship · implementation – bringing to the stage of practical application · maintenance – including not only monitoring for correct operation, but also the development of technical documentation for the created application.
The most common vacancies are Ruby Developer, Ruby/Rails Developer, RoR Developer, and Ruby Engineer. A general requirement is to have at least an intermediate level of English. Employers also demand proven experience (at least 2 years) in Ruby programming, as well as working with Rails or Grape frameworks, PostgreSQL or MySQL database management systems. Bonuses and advantages for the applicant are ReactJS and Docker development skills, and Git team development.
There are fewer IT specialists than PHP programmers, and thus there is more demand . This explains the higher salaries of Ruby developers.
Employers' requirements for Ruby developers of mid and especially senior levels may include: • strong teamwork skills - the ability to get along with other people and cross-functional teams; • tolerance for stressful situations ; • ability to work in a company without a rigid hierarchy ( an especially important requirement for many startups); • strongly developed written and spoken communication skills; • proactivity; • responsibility; • ability to meet deadlines; • an entrepreneurial, product-oriented mindset.
