About the Team 

The Global Security Support Center (GSSC) plays a critical role in strengthening ServiceNow’s internal and external security posture and acts as a key interface with customers on security‑related matters. 

GSSC AppSec is a globally distributed team responsible for owning the Customer Penetration Testing & Security Findings (CPT & SF) program, partnering across the Security Organization to reduce risk, handle escalations, and represent the voice of the customer. 

This role is focused on ServiceNow instance security, helping customers and internal teams identify, understand, and remediate insecure configurations and instance‑level security gaps. 

Role Summary 

As an Staff Application Security Engineer in GSSC AppSec, you will secure ServiceNow instances by identifying configuration‑driven security risks, validating customer‑reported findings, and driving clear, actionable remediation guidance. 

This is a hands‑on technical role that blends application security expertise with deep ServiceNow platform knowledge. At the senior end of the range, you will operate with minimal direction, own complex instance‑security problem spaces, and influence how GSSC AppSec scales instance security guidance and posture improvements globally. 

Key Responsibilities 

ServiceNow Instance Security & Hardening 

Assess ServiceNow instance configurations against security baselines and identify misconfigurations that impact confidentiality, integrity, or availability. 

Develop and maintain prescriptive instance‑hardening guidance covering authentication, access controls, encryption, logging, monitoring, and operational security. 

Translate security requirements and risk into clear, customer‑consumable recommendations that can be implemented by teams with varying security maturity. 

Identify recurring misconfiguration patterns and drive systemic improvements (guidance, tooling, checks). 

AppSec & Customer Security Findings (CPT & SF) 

Triage, validate, and contextualize customer‑reported security findings where instance configuration or deployment patterns are a contributing factor. 

Distinguish between product vulnerabilities vs. configuration issues, documenting impact and appropriate remediation paths. 

Partner with Product Security, Engineering, and other Security teams to resolve complex or high‑impact findings. 

Support escalations and high‑visibility customer interactions as an instance‑security subject‑matter expert.
