We are looking for a great Software Engineer to join our team! The position will include building great products, tackling interesting challenges, and contributing to our engineering culture. We expect you to work in pairs, use test-driven development a lot, be experienced in building complex web and mobile applications, and write both clean and maintainable code.

Once you join us, you will build one of the next products:

  • Mailtrap.io - our headliner in the world of safe email testing (with over 550,000 users)

  • Calendly - one of the most popular scheduling tools in the world
  • BrightBytes - a platform for educators that empowers school-wide improvement through data-driven insights
  • OfficeSpace - a powerfully simple facility management software used by well-known companies in Silicon Valley and outside of it.

Check other examples of the products we built.

We write Ruby and JS 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.

Required skills & experience

  • Excellent general programming skills
  • Extensive knowledge of Ruby, Ruby on Rails and its testing frameworks
  • Experience in writing JavaScript applications using modern client-side frameworks/libraries (React & Redux, Angular, Backbone, Vue etc.)
  • Practical experience with different DBs (RDBMS, Key Value / Tuple Store, Wide Column Store / Column Families, Document Store)
  • Comfortable with the UNIX/Linux command line
  • Experience in Test-Driven Development and pair programming (good to have)
  • You have strong technical expertise and can work with complex codebases
  • Good English (ability to communicate fluently)

Responsibilities and expectations

  • End-to-end product development
  • Write reusable and maintainable code 
  • Write tests to thoroughly validate the correctness of your code 
  • Actively contribute to identification of the problems and their solutions 
  • Be able to collaborate in cross-functional team to ensure the project meets business objectives and compliance standards
