- Collaborate with network architects, systems engineers, and operations teams to deliver scalable, compliant, and sustainable infrastructure solutions.
- Maintain detailed technical documentation, standards, and operational procedures to ensure consistency and compliance.
- Contribute to modernization efforts by applying innovative technologies and best practices from Top of Rack to Network Border.
- Must possess an active Department of Defense (DoD) TS/SCI clearance with Counterintelligence polygraph.
- Bachelor's degree in Computer Science, Engineering, or related field (or equivalent experience).
- 5+ years of experience designing, deploying, and automating enterprise or cloud network infrastructure.
- Proficiency in Python or Go for programming/scripting.
- Strong hands-on experience with automation frameworks (specifically Ansible) to automate network configurations.
- Experience with networking protocols and APIs, ideally Open vSwitch and/or RESTful APIs for network devices and services.
- Proficiency in network topologies and architectures (VLAN, LAN, WAN).
- Experience operating and troubleshooting network routing, interconnectivity, performance, and configuration issues.
- Linux systems experience (implied under network troubleshooting and application interaction).
- Ability to communicate effectively with technical and non-technical stakeholders.
- Strong time management skills in a fast-paced environment.
- Experience with SONiC and/or Cumulus Network Operating Systems (NOS).
- Experience with rail-optimized technology.
- Experience with OpenShift networking, including:
- Open vSwitch (OVS) / Open Virtual Network (OVN)
- Kubernetes Container Network Interface (CNI)
