We expect you to work on both Railsware products and solutions designed for our clients:

  • Mailtrap.io - our headliner in the world of safe email testing (with over 1M users)
  • Coupler.io - a tool for data import between different systems to build smooth data flows
  • Titanapps.io - a set of productivity tools for Jira and monday.com designed for professional teams
  • Tradezella - №1 trading journal and analytics platform

Check other examples of the products we built.

We write Ruby and ReactJS code a lot; however, our codebases are often polyglot, and we keep on experimenting with technologies like Elixir or Go in real production. Therefore, additional experience in other languages and frameworks is, of course, a plus.

  • End-to-end product development
  • Write clean, reusable, and maintainable code 
  • Write tests to validate the correctness of your code thoroughly 
  • Actively contribute to the identification of the problems and their solutions 
  • Collaborate in a cross-functional team to ensure the project meets business objectives and compliance standards
  • 5+ years of experience with Ruby development
  • Excellent general programming skills, ability to work with complex codebases
  • Extensive knowledge of Ruby, Ruby on Rails, and its testing frameworks
  • Extensive experience with ReactJS 
  • Practical experience in different DBs (e.g., RDBMS, Key Value / Tuple Store, Wide Column Store / Column Families, Document Store)
  • Experience with cloud hosting providers (e.g., AWS, Google Cloud, Digital Ocean, Heroku) 
  • Comfortable with the UNIX/Linux command line
  • Spec-driven, AI-orchestrated development: you plan deeply and know how to work with AI agents effectively 
  • Proficiency in test-driven development 
  • Comfortable taking the lead on projects and working without lots of oversight
  • Product-oriented mindset
  • Good English (both written and spoken)

Will be a plus 

  • Experience with pair programming
