Escalation engineer at Zscaler in Bengaluru: the deepest technical rung of support, debugging networking and security issues across the Zero Trust Exchange for enterprise customers.

This Bengaluru role was posted on 22 October 2026. Zscaler's escalation engineers take the cases frontline support cannot solve: protocol-level debugging, packet captures and deep dives across its global security cloud. Note the bar in the listing: a minimum of 8 years of support engineering experience, so this is a senior support role, not an entry point.

Its platform securely connects users, devices and applications for thousands of enterprise customers, protecting them from cyberattacks and data loss. The company says it is building an AI-native enterprise around a Human + AI model of work. Learn more on Zscaler's website.

The role in plain terms

You are the engineer other engineers escalate to. The work is troubleshooting production issues for large enterprises: reading packet captures, working through HTTP, DNS, SMTP and TLS behaviour, reproducing customer problems and pushing fixes or workarounds through engineering. The listing asks for strong Linux/Unix fundamentals and familiarity with tools like tcpdump and Wireshark.

What you will do

Per the employer's listing, you will:

Provide second line phone/email consultation to independently debug complex security/network problems
Interface with Engineering and assist the customer with testing or troubleshooting
Reproduce customer issues to verify problems and provide feedback to Engineering and Operations teams
Create entries in our technical support online database to accurately document any incident resolution that is not found in our knowledge base
Understand the product direction and customer use-cases and provide input on product & code changes through all points of the product cycle

What the employer asks for

These requirements are quoted from the employer's listing, kept in their exact words so eligibility details are not distorted:

Demonstrated curiosity and active exploration of AI tools, with a proven history of integrating new technologies to enhance daily workflows and augment problem-solving
Minimum 8-year experience working as Support Engineer/ Sr. Support Engineer supporting networking or web security products
Experience with operating systems such as Linux, Unix, and Free BSD
Experience troubleshooting network issues and familiarity with the necessary tools (Ping, Traceroute, MTR etc)
Expert knowledge of protocols such as HTTP, SMTP, FTP, DNS etc
Familiarity with Network Protocol Analyzers (tcpdump, Wireshark), Network Security (SSL/TLS, VPNs, Firewall, IDS/IPS), authentication systems (LDAP, MS AD), VPN technologies (IPSec), and scripting (SHELL, Python, Perl)

Who this role suits

Veteran support or network engineers (8+ years per the listing) who genuinely enjoy debugging hard networking problems and want to do it on one of the biggest security clouds in production. Strong fit for people coming from network security, SASE or enterprise support backgrounds. Not for freshers or for engineers who want to write product code full time.

Practical notes

Expect scenario-based interviews: how you isolated a vague customer issue, which captures you pulled and what the packets showed. Brush up SSL/TLS inspection and VPN concepts specifically - Zscaler's platform sits in-line on customer traffic. Zscaler also asks for demonstrated use of AI tools in daily workflows, so have a real example ready.
