Working as a technical architect for network design, optimization, and automation involves providing technical specifications, preparing the BoM for a new solution, following up on the roadmap, and updating the network, software, and licenses. Additionally, preparing for network automation using Python scripts and Ansible is essential. Continuous follow-up with vendors and customers for any new technology solutions, providing RFI, BoM, technical specifications, proof-of-concept tests, and preparing documents for field trials is also part of the role. Moreover, following up with the project team for new design and deployment is crucial.Providing advanced technical support and advice to NTG Technology Group during solution design and implementation.Undestanding emerging technologies and how to maximize their potential for the benefit of the NTG and advising on stragegic direction of the NTG Network and NTG Infrastructure.
