Ruby Developer


Ruby Developers utilize Ruby to develop back-end components of a web application utilizing the Model-View-Controller framework. This can include anything from designing plug-ins to building command line utilities on a computer. Ruby Developers are also responsible for supporting front end developers by integrating third party web services into applications. 

Ruby on Rails is quickly gaining popularity, creating a demand for Ruby Developers. Although Ruby contains properties found in many general purpose programming languages, a solid understanding of Ruby syntax and common libraries within Ruby such as RSpec and Resque is required to effectively utilize the code.


Ruby Developer responsibilities may include:

  • Build data processing scripts.
  • Maintain code integrity.
  • Automate processes within the application.
  • Design command line utilities.
  • Design scalable applications.



Ruby is quickly becoming a popular programming language due to its easy-to-learn framework. In order to utilize Ruby to create the best products possible, a skilled Ruby Developer will:

  • Possess an eye for detail in order to spot errors in code.
  • Possess a general knowledge of common programming fundamentals.
  • Be committed to delivering the highest quality product possible.
  • Think spatially in order to design effective applications
  • Familiarize themselves with the Ruby framework.



Entry-level positions typically prefer that candidates have a Bachelor’s Degree in computer science or a related field. Employers will tend to look for candidates with experience in full stack web development as well as other common programming languages such as Java and CSS.
