As an IT Infrastructure Architects design and implement information systems that support an enterprise infrastructure. You will provide the necessary technical infrastructure for the development of new and existing infrastructure technologies and system requirements. 

Improve efficiency and streamline operations. enhance design specs, create technical documentation, implement control concepts and deliver expected outcomes. Collect performance data to monitor systems resource usage and failures rates and provide solutions and recommend changes. ensure scalability and anticipate capacity growth through careful planning and awareness of industry, business and client’s growth trends. Design activities rely on accurate data, sensible KPIs and performance metrics to improve processes and bridge gaps

Primary Responsibilities:

Conducting research on emerging and existing technologies. Recommend system alternative technologies and infrastructure development efforts that increase infrastructure flexibility, reliability, stability, scalability, resilience, availability, performance and cost effectiveness. All collective research efforts will contribute to the creation of architectural road maps that leverage software and cloud technologies. Research customer interaction, policy adherence, enterprise processes. May act as the subject matter expert of architectural virtualization.
