  • Implement infrastructure upgrades, including hardware replacements, patch management, and scheduled system updates.
  • Formulate disaster recovery mechanisms, including failover systems, data backup strategies, and business continuity planning.
  • Manage and support virtual and hybrid cloud networking environments across AWS, Azure, or other cloud providers.

Your Skills and Experiences:

  • Solid, production-proven experience in enterprise network engineering, with in-depth knowledge of TCP/IP, dynamic routing protocols, Spanning Tree, and HSRP.
  • Hands-on expertise with enterprise networking hardware from providers such as Cisco Meraki, Cisco, Aruba, Fortinet, or Juniper.
  • Practical scripting capabilities using Python, Terraform, or Ansible to automate repetitive infrastructure tasks.
  • Experience with network monitoring systems such as SolarWinds, Cacti, or PRTG.
  • Strong working knowledge of core network services, including DHCP and IP address management (IPAM).
  • Familiarity with agile frameworks at scale (Scrum, Kanban) and experience supporting agile transformation.
  • Strong root-cause analysis skills for resolving high-pressure, business-critical outages.
  • Fluent in English, both spoken and written, with the ability to explain complex infrastructure topologies to non-technical stakeholders, and an autonomous, collaborative, problem-solving mindset.
