  • Ability to lead the design and implementation of a solution
  • Experience in leading project teams
  • Willingness to be involved in topics that go beyond programming and design, such as responsibility for technical areas or communication with other teams
  • Proactive attitude, independence in taking action
  • Extensive experience in programming and readiness to implement key system elements as well as involvement in code reviews
  • Good knowledge of methods of creating concurrent programs and distributed systems
  • Ability to critically analyze created solutions in terms of performance (from estimating the theoretical performance of designed systems to detecting and removing actual performance problems in production)
  • C1 level in English and Polish.

What we offer

  • Projects focused on extreme performance and high code quality – clean code and solid code reviews are our standard
  • Collaboration within an interdisciplinary, self-sufficient team (including DevOps, database experts, backend developers, product designers, and QA engineers)
