Global Video Area aims to lead the development, engineering and deployment of video services in all the countries where Telefonica is present, meaning a significant percentage of the network occupancy.

Those services are mainly distributed in IPTV and OTT, with a live, vod or advanced tv user experience, what demands a cutting-edge, robust and competitive video platform.

Precisely, the group for this vacancy, so-called Video Core Technologies, is in charge of the pure video technology underneath those services.

We dive into the tecnology to establish criteria in the architecture of video headends, homologate third-party components such as encoders, packagers, muxers, scramblers or managers and, even, implement in-house solutions to solve the interoperability issues of a complex E2E ecosystem.

The exposure to video knowledge and troubleshooting low level problems are true relevant on the daily basis of the group, enriched with a laboratory of tools for analysis and conformance of video standards.


We are looking for a candidate to lead the software capabilities of the group, able to impement our own components to resolve interoperability issues, design a low-level infraestructure of testing for video headends (encoders, packager, muxers among others) and cloudify our solutions leveraging microservices in Kubernetes.

The expasion of video in more and more countries make new challenges that require a candidate to join the team with real passion and seniorty in the video industry to keep up the group as a refrence in the video knowledge.


The candidate will be involved in a wide variety of tasks focused on mastering the sofware capabilities in video technology of the group :

  • Implement components to solve interoperability issues of the particular Telefonica's video ecosystem in :
  • Protocols such as Smooth Streaming, HLS and DASH
  • ISOBMFF and MPEG2-TS containers
  • Video / Audio / Subtitles / Thumbails streams.
  • DRM Encryptions for systems such as Widevine, PlayReay and Fairplay.
  • Implement conversion between different video packaging protocols.
  • Cypher and decypher of common encryption algorithms (cenc and cbcs).
  • Extend the video tools of the group with ad-hoc components for specific use cases in production.
  • Automate testing of third-party components by using the common SOAP / REST / Swagger interfaces, video probes and conformance tools.
  • Design a microservices architecture based on Kubernetes workflows to conduct test plans.
  • Cloudify the current video-headend architecture in a private and / or public scenario. Experience in AWS, Google Cloud and Microsoft Azure will be valued.
  • Assure the software madurity of the group with Continous Integration and Continuos Delivery practices.
  • All the sofware skills above must be connected to a depth knowledge on video technology, so that the candidate can detect conformance issues and contrast with standard expectations.

    A intense collaboration is needed with other groups of the video chain : CDN delivery, Players and backend Platform.


    Being a software reference of the group and mastering the video technologies is the main challenge for the candidate. It is expected that he / she can contribute on the two main lines of activity : video head-end analysis and video components implementation.


    Master of Science (MSc). Preferred Tecommunication Engineering, but any other branch will be considered as long as video expertise is demonstrated.


  • Double profile : video technolgy and software engineer.
  • Analythical criteria to detect issues on video compliance, quality issues and transport information.

  • Software : Python, C#, C++, Docker, Kubernetes, Jenkins, Ansible, Vagrant, Swagger.
  • Encoding : AVC, HEVC, AV1, AAC, Dolby, DVB-SUB, DVB-TXT,...
  • Packaging : Smooth Streaming, HLS, MPEG-DASH, MPEG2-TS, ISO-BMFF, CMAF.
  • DRM : PlayReady, Widevine, Fairplay.

    At least demonstrated 4 years experience on video head-ends, involved in development and engineering activities.
