L2 Support Specialist

Vedoucí týmu L2/L3, který podporuje síťové prostředí. Tým pracuje převážně s technologiemi CISCO, kde podporujeme SDWAN, SDLAN (SD ACCESS) a SDDC infrastrukturu. Denní odpovědností je práce s týmem, účast na eskalacích a účast na incidentech s vysokou prioritou. Tým se skládá z 19 lidí, kteří pracují s těmito novými technologiemi. Vzhledem k tomu, že zákazník prochází transformací, je v tuto chvíli před ním mnoho výzev, protože je třeba tým proškolit, naučit novou strukturu a topologii sítě a navíc je třeba udržet služby pro zákazníka bez problémů.
