Transatel recently joined NTT Group, the 5th largest telecom operator in the world, with a turnover of over 92 Bn. euros. Transatel now combines the agility of a headcount of 200 with the firepower of a multinational group: backed by this powerful framework of economic ties, Transatel is now in a position to further extend its business development, on a massive and global scale.

This can only be achieved if Transatel’s know-how and track record is known and integrated as a key component of the Group’s product portfolio.
Within the Telecom department, you will be a referent and expert on Transatel’s mobile data core network.

In close collaboration with the architectural team and within a team of expert engineers, you will develop and document the engineering solutions for routing data on our network. This applies to both new services and the consolidation of existing infrastructures.

  • design technical solutions that meet the needs of the projects, while maintaining the operability of the platform
  • document each topic and transfer knowledge to the operation and support teams
  • (possibly) collaborate on the platform support

Your profile

With a degree in Software Engineering, Telecom or equivalent, you have at least 5 to 8 years of experience in telecommunications, including GGSN / PGW.

Technical skills required:
  • Working knowledge of IPv4 routing and related protocols (BGP, OSPF, etc.)

Your natural curiosity and zest for innovation compels you to keep up to date with the telecoms industry.

Able to communicate with all levels of the company (both orally and in writing), you are organized, rigorous, and comfortable in a very dynamic environment.

English fluency is essential. German is a plus.
