Purpose of the job

You will be part of a team of several quality of service and radio optimization engineers, where you will be responsible for carrying out RAN engineering studies (quality monitoring and optimization) for subsidiaries involved in the REC, and ensuring the consistency of the configuration and activation of 2G, 3G, 4G, 5G (and soon 6G) radio features over time. You will also provide support to subsidiaries involved in the REC to ensure the technological evolution of existing radio sites through the management of technology trials and the implementation of group recommendations to meet our customers' expectations in terms of improving radio quality of service. In terms of ongoing activity for our customers, you will participate in the analysis of drive tests and the operation of automatic optimization tools (C-SON) to continuously improve radio performance.

Duties and responsibilities

As a quality of service and radio optimization engineer, the main activities will include:

• Analyzing the network's key performance indicators and proposing solutions to resolve the problems detected.
• Implementing the engineering rules and recommendations in terms of configuration and group features in the subsidiaries on an annual basis (audit and then support for trials and implementation).
• Supporting the subsidiaries in local trials on the technological developments of the radio network.
• Analyzing drive tests and call traces periodically as part of QoS campaigns, or on request as part of cluster acceptance (new sites, trials, swaps, etc.).
• Regularly auditing the radio configuration (including MSP operational audits) and implementing radio optimization automation functions (operating C-SON tools in accordance with group recommendations).
• Level 1 support for the subsidiaries for radio optimization, to assist the local teams with local optimization.

Job specification
