  • Very good knowledge of fundamental Internet protocols and technologies (DNS, HTTP, cookies and others)
  • Good knowledge of basic methods of creating concurrent programs and distributed systems (from thread level to geo-distributed clusters level)
  • Practical ability to observe, monitor and analyse the operation of production systems (and draw valuable conclusions from it)
  • The ability to critically analyze the solutions created in terms of performance (from estimating the theoretical performance of the designed systems to detecting and removing actual performance problems in production)
  • General knowledge of issues (typical problems and methods of solving them) in the areas of 'high scalability' and 'high availability'
  • C1 level in English and Polish

Nice to have:

  • Experience in the AdTech/Real Time Bidding space

What we offer:
  • Projects focused on extreme performance and high code quality – solid code reviews are our standard
