Senior Ruby on Rails Developer

11000-18000 PLN + VAT (B2B)

We are looking for a Senior Ruby on Rail Developer. Partially remote work possible. If you recommend us someone whom we later hire, you will get 1,000 PLN.

We are looking for someone who has already worked in Ruby on Rails for at least 3 years and who because of their experience can bring new solutions to the project, which contributes to the technological development of our company and our products.

At JohnnyBros we develop products for an internal customer, which gives us freedom when it comes to making decisions regarding the process of creating these products. It also means that we do not look for new assignments. Thus, the ability to talk to business clients is not required. We also do not require more advanced English skills than it is necessary to read technical documentation.

The applications we develop are visited by ca. 500,000 users per month (there are months when the number of users is multiple times higher) and this number is still growing. Because of that the job primarily focuses on solving optimization problems, refactoring, and launching new technological solutions, while creating new functionalities is a secondary task. During the recruitment process we will be happy to present more details regarding our work and projects we carry out.

We require:

  • Ruby on Rails >=5;
  • RSpec;
  • MySQL;
  • Git.

We appreciate the knowledge of:

  • JavaScript;
  • Bash.

What you can expect from us:

Most importantly, a positive atmosphere and a relationship based on trust and respect. The company is our second home where we gladly come back on Monday morning.


  • cooperation with experienced web developers and full code review:
  • private medical care;
  • paid vacation leave;
  • Benefit System;
  • flexible working hours;
  • influence on improving your and your team’s work;
  • financing hobby courses - to help you develop your hobby, we will pay 70% of the price of hobby courses chosen by you;
  • paid sabbatical - JohnnyBros veterans are given an additional two-month paid sabbatical;
  • integration trips - we build a positive atmosphere in our team also outside the office;
  • tourist Fridays - once a month we go out together to get to know each other better;
  • foosball - we know that taking breaks from work has a positive impact on the employee’s condition;
  • workplace with Mac OS;
  • tasty sandwiches, tee, and coffee;
  • and many, many more.

Salary 11,000-18,000 PLN + VAT (B2B) or 9,000-15,000 gross (employment contract)
