  • Have worked on projects with an active production environment
  • Have had the opportunity to participate in the development of scalable dispersed applications
  • Understand the algorithmic complexity of solutions
  • Get along well with people and embrace teamwork
  • Have no fear communicating with clients (calls and emails)
  • Are familiar with at least one web framework and ORM (we use Flask and SQLAlchemy, so knowledge of these topics is a big plus!)
  • You are able to run a variety of tests and know how to optimize them and are familiar with py.test
  • Are aware of cloud solutions and know a bit about monitoring dispersed infrastructure (AWS rules in our team)
  • You know in and outs of developing and documenting REST APIs
  • You know PostgreSQL, MySQL or other RDBMS (knowledge of AWS Redshift is a big plus)
  • You feel comfortable using Linux (Debian) both as a user and sysadmin

It would be awesome if you also:

  • Have previous experience in building web applications
  • Have had a chance to use e2e testing tools (Selenium, Cypress) in the past
  • Know the tools to user interface creation (JS, React, Redux)
  • Are familiar with cloud solutions (AWS rules in our case)

What can you expect from us?

  • Flexible cooperation
  • An attractive salary (11000-14000 PLN net on a VAT invoiced B2B contract) and a chance to receive company shares (a bonus for the chosen ones)
  • A development tools package with a regularly updated resource library, English classes, regular events with lectures given by our colleagues, knowledge-sharing (tech and business) groups
  • Private health insurance
  • A MyBenefit card
  • A lunch card
  • Flexible working hours
  • The possibility to work remotely, provided you are able to come to the office if and when required

About Team

Tomek Chmielewski - Python PM

How do we work?

Currently, we are organized into two teams: one Feature Development Team, which focuses on developing new features and one Maintenance Team, which provides additional tools and optimizes already-implemented solutions. We’re mostly generalists, but team members are semi-specialized in their domains. We do unit tests, functional tests, and “blackbox” testing, using the py.test (with Selenium) and Mocha testing frameworks. Feature Development Team works in Scrums, while the Maintenance Team works in Kanban. Roles within the teams include: Developer, DevOps, Project Manager and Tech Lead.

What makes us special?

We are developing one of the most challenging project in Wrocław (seriously!) and we love to celebrate achieving our sprint goals with cakes!

We welcome people who:

  • Think both logically and outside the box
  • Are creative
  • Are not afraid of being confronted with a variety of problems and opinions
  • Are able to effectively manage their time

We mostly use:
