Task Description

You will join a small team of Networking/IT experts responsible for the network monitoring layer of BICS. 

>Take the responsibility to maintain and further develop a home-grown mediation platform that decodes, enriches and performs statistical processing in real-time on high volume flows of network signaling data (coming from probes and active testing components) used for customer-facing reporting and monitoring.
>Initiate and lead technical projects to implement new data processing pipelines or adapt the existing ones, involving the required technical resources: Python developer, business analyst, network engineer, system administrator, etc. Co-ordinate their activities and take an active part to the development and analysis tasks.
>Interact with business analysts and technical experts to translate business requirements into algorithms to process the network data and generate the expected analytical results, e.g. in terms of subscribers behaviour patterns like spam or fraud.
>Implement the data processing logic in Python (together with other Python developers in the team) and deliver the outputs to various downstream consumers (e.g. the data science, BI and Hadoop teams) for further processing, longer term storage and presentation.
>Validate the implemented logic by testing with real network data, looking into the Python source code, message per message call traces, statistics stored in various databases and the final reports as presented to the users (based on QlikView).
>Maintain a clear documentation of the whole platform: components, data flows, algorithms, etc.
>Perform the day-to-day support for the mediation platform, investigating tickets opened by internal or external customers. 
 >Develop following best-practices and company standards:
•Keeping code up-to-date in Git
•Developing unit tests
•Automating deployment process as much as possible
>Take ownership of the probing platform for the engineering and vendor management activities. Interact with the vendor to plan the future evolutions of the platform (new features, upgrades, capacity planning) and to track the open issues, together with the BICS Assurance personnel.
