Responsibilities:

We are looking for a  Senior Network Engineer to help build, operate, and evolve the network infrastructure behind our global SaaS platform.

This is a  hands-on, automation-focused network engineering role for someone who enjoys working across data center, cloud, Linux, and virtualized network environments. You’ll own networking end-to-end—from deployment and configuration to monitoring, troubleshooting, automation, and continuous improvement.

You don't need to be a pure network architect, but you should have strong networking fundamentals, understand how modern network infrastructure is designed, and be able to independently troubleshoot complex problems and implement solutions with limited direction.

You’ll work closely with Engineering, SaaSOps, and Customer Success teams and will also help own our lab and data center network infrastructure in Santa Clara.

What You’ll Do

• 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 experience.
• Experience supporting infrastructure for a  SaaS, software, or technology product company .
• Experience working across both  physical and virtualized network infrastructure .
• Experience with public cloud networking in  AWS, Azure, or GCP .
• Experience owning or supporting  lab or data center environments .
• Experience developing network automation, infrastructure tooling, or configuration-management solutions.

What We’re Looking For

We’re looking for someone who combines strong networking fundamentals with a modern infrastructure mindset. You may come from a traditional networking background, but you should be comfortable working beyond routers and switches—using Linux, automation, cloud technologies, and software-defined networking to operate infrastructure at scale.

You don't need to check every box. If you have strong networking fundamentals, are hands-on, enjoy troubleshooting complex infrastructure problems, and are interested in expanding your skills across automation and modern network technologies, we'd like to hear from you.
