Moderate understanding of service provider technology, protocols, and general troubleshooting (BGP, MPLS). Experience with network automation methodologies and tools (Ansible, scripting, and coding) Proficient in troubleshooting and fault isolation/resolution. Demonstrated experience with network documentation and diagrams (Draw io, Visio). Ability to work in a team environment, but self-driven to complete assignments while continually developing proficiencies in processes Strong written and verbal communications, team building and collaboration skills. Must be able to obtain and maintain a Secret Clearance. Must be able to obtain and maintain an active DoD IAT Level II cert (Security+ CE, etc) Preferred Qualifications. Proficient with Juniper SDWAN Juniper Certified or Cisco Certified (CCNP EI) Proficient with network automation Experience with general Linux administration. Experience with some of the various virtualization technologies (VMWare, Proxmox, KVM, Docker, Kubernetes) Knowledge of ITIL Change & Configuration Management. At Leidos, we don't want someone who "fits the mold"-we want someone who melts it down and builds something better. This is a role for the restless, the over-caffeinated, the ones who ask, "what's next?" before the dust settles on "what's now." If you're already scheming step 20 while everyone else is still debating step 2... good. You'll fit right in.
