Our activities include, for example, the implementation and optimization of radio algorithms, performance analysis, and the development and optimization of functionalities related to data transmission or call handling.

  • possess knowledge of Git, Gerrit, Jenkins technologies,
  • use English at a communicative level (min. B2).
