The ideal candidate will possess strong expertise in RF backhaul technologies, enterprise networking, cloud (Azure) networking, Infrastructure as Code (IaC), and robust experience with both Fortinet and Cisco IOS platforms. You will ensure high availability, security, and performance for both office and field networking environments, often in remote or challenging locations.
Key Responsibilities
Design, deploy, and support enterprise network solutions across diverse operational environments (offices, remote field sites, drilling rigs, processing plants, etc.).
Implement and maintain RF backhaul networks (point-to-point/multipoint microwave, licensed/unlicensed links) ensuring reliable connectivity in remote oilfield locations.
