• Deploy, operate, and improve data center network infrastructure , including routing, switching, network security, load balancing, and connectivity.
• Support network infrastructure across data center, cloud, and virtualized environments , ensuring reliability, scalability, performance, and security.
• Own networking for our Santa Clara lab environment , including deployments, maintenance, troubleshooting, and occasional hands-on data center support.
• Automate network provisioning, configuration, monitoring, and operational tasks using Python, Ansible, Bash, or similar tools.
• Configure and manage network infrastructure, with a significant portion of our environment running on Juniper and JunOS .
• Work with software-defined networking (SDN), Network Functions Virtualization (NFV), and virtualized network environments .
• Troubleshoot complex infrastructure issues across network, Linux operating system, and application layers .
• Partner with Engineering, SaaSOps, and Customer Success teams to deploy and support networking solutions across private and public cloud environments.
• Monitor network health and performance, identify potential issues, and improve network observability and operational reliability.
• Participate in an on-call rotation supporting mission-critical network services.
• Coordinate and execute occasional data center visits for infrastructure deployment, server maintenance, and operational support.
• Evaluate new networking technologies and contribute to technical standards, documentation, automation, and infrastructure best practices.

Requirements

• Approximately 5+ years of hands-on network engineering experience , or equivalent experience demonstrating strong networking expertise.
• Strong understanding of networking fundamentals , including TCP/IP, routing, switching, VLANs, network security, load balancing, and common routing protocols.
• Hands-on experience deploying, operating, and troubleshooting data center network infrastructure .
• Experience working with Linux systems and troubleshooting issues across network, operating system, and application layers.
• An automation-first mindset with experience using Python, Ansible, Bash, or similar tools to automate network configuration and operations.
• Experience with software-defined networking (SDN) and familiarity with Network Functions Virtualization (NFV) or virtualized networking environments.
• Experience supporting networking in cloud or hybrid infrastructure environments .
• Experience with network monitoring, observability, performance optimization, and production incident response.
• Ability to independently troubleshoot complex infrastructure problems and implement solutions with limited direction.
• Strong analytical, communication, and collaboration skills and the ability to work effectively across engineering teams.
• A proactive, ownership-driven approach and interest in continuously improving how network infrastructure is deployed and operated.

Nice to Have

• Hands-on experience with Juniper networking platforms and JunOS .
• Strong Cisco experience may also be considered, particularly for candidates with strong networking, Linux, and automation experie
