Preferred qualifications include background in Internet and Security technologies (SWG, Sandboxing, PAC files, SCIM), relevant vendor certifications (CCNP, CompTIA Security+), and hands-on experience with public cloud environments (AWS, Azure, GCP). You must be a US citizen due to the nature of customers assigned to this role. Zscaler values impact over activity, customer obsession, collaboration, and accountability.
