About The Position

Our client is an innovative, established global company with a start-up culture that provides a range of wireless communications solutions and specialize in mission critical infrastructure.

You will design (More optimization as the design is already completed), implement, and maintain network operations across our client's global offices and cloud deployments, with a strong DevOps mindset — automating workflows, managing infrastructure as code, and building repeatable, resilient processes. You will be responsible for maintaining comprehensive documentation of IT policies, procedures, hardware, and software.
