About Versa Networks

At Versa Networks, we are redefining the future of networking and security through an

industry-leading platform that converges SD-WAN, Security, and SASE into a unified

architecture. Versa powers some of the world's largest enterprise and service provider

deployments, helping organizations build secure, scalable, and highly resilient modern

• Partner closely with Engineering to isolate defects, validate fixes, and improve product

quality

• Drive technical escalations across multiple teams and stakeholders

• Participate in root cause analysis and provide strategic recommendations

• Develop knowledge base articles and troubleshooting guides

• Mentor junior engineers and help elevate technical capabilities across the team

• Become a subject matter expert in one or more technical domains

Required Experience
