OpenX is focused on unleashing the full economic potential of digital media companies. We do this by making digital advertising markets and technologies that are designed to deliver optimal value to publishers and advertisers on every ad served across all screens.

At OpenX, we have built a team that is uniquely experienced in designing and operating high-scale ad marketplaces, and we are constantly on the lookout for thoughtful, creative executors who are as fascinated as we are about finding new ways to apply a blend of market design, technical innovation, operational excellence, and empathetic partner service to the frontiers of digital advertising.

Who we are looking for:

At OpenX Poland, we’re looking for talented, communicative, and curious engineers to join our amazing team in Cracow, Poland. Currently, we’re looking for a Software Developer in Test (Python) who will join our Full-stack team.

You will have a chance to work in some aspects of agile application development, including our highly efficient and available serving platform, and your opinions will be considered in certain phases of product development, starting from requirements to validation and deployment. You will assist other engineers to ensure that our processes are defined, documented, tested, and easy to use.

The team is using the following technologies:

Frontend: JS/TS, React, Material UI

API: Python

Backend: Java, Go, Erlang, Elixir

CICD: Cloudbuild, Spinnaker

On daily basis, we are using the Scrum framework with an open-minded attitude to adapt the process to our needs. Within the team, you will have the opportunity to work closely with other SDETs focusing on different domains (both frontend and backend), as well as be a part of the QA Guild focusing on making impactful changes to our tools and processes.
