WE ARE HIRING Senior Ruby developers NOW!

If you're an engineer and would like to work in a quality-oriented software house talk to us.



We are looking for passionate software engineers to join our company to work on challenging ongoing projects.

We work in small teams, we do Test Driven Development and use Agile methodologies.

We focus on long-lasting partnerships with ongoing projects rather than short term cooperation with startups.

We really focus on delivering quality solutions, quick and dirty is not an option most of the time and our clients do understand that.

Apart from clients' projects we also spend time on our internal projects, tools and open source.

You should definitely talk to us if you have extensive knowledge of computer science, web development and other related topics (algorithms, database systems, optimization, internet protocols, devops etc.).
Additionally excellent coding skills and very high productivity are required. You should be able to deliver code in much shorter time than Ruby Developer. The code should have excellent quality, according to our best practices and set standards. It must be very easy to understand, maintain and all related aspects must be taken into consideration (such as general application performance, data migration, deployment process, security and impact on other features).

Senior Developer is very responsible, self-reliant and can move whole project on this own taking care of not only developing new tasks but also making sure that it is working without any problems all the time.

You should be an expert in one or two categories like optimization, database systems, devops, Ruby on Rails etc.


  • preferrably technical education (we hire software engineers mostly)
  • excellent knowledge of Ruby and Ruby on Rails
  • excellent knowledge of Javascript
  • excellent knowledge of SQL and database systems
  • excellent knowledge of performance optimization
  • very good knowledge of algorithms and data structures
  • very good knowledge of git
  • good knowledge of devops
  • very good english (we work with foreign clients only)

  • implemented uploading of large files with high throughput
  • implemented integration with various apis using different protocols (SOAP, REST, json)

What would be your responsibilities:

  • deliver new features (fast)
  • perform code reviews

  • research different solutions for tasks


  • 12 500 - 20 000 PLN nett on vat invoice (other forms possible) depending on your experience
  • Great open minded team and superb work environment
  • A lot of learning capabilities

is the key

Everyday work is an excitement here, at Visuality. Nevertheless, we try to make it even more interesting by organising extra activities. Once a month we put the projects aside and organise an investment day to make sure that we all learn something new. We go to conferences, mentor at workshops (RailsGirls - we love you!) and try to contribute to the coding world with our open source projects.
