Job summary

Quarterhill seeks a ServiceNow Developer to design, build, and maintain features in custom-scoped applications for multiple agency clients. You will craft Business Rules, Script Includes, UI Policies, and ACLs while integrating external systems and ensuring data integrity across ITSM and other modules.

You will diagnose issues, document root causes, and support cross-platform administration on Windows and Linux. A hands-on, diagnostic-first mindset and clear communication are essential.

Qualifications

• 2-4 years of hands-on ServiceNow development/administration experience.
• Solid understanding of the ServiceNow scripting model (Business Rules, Client Scripts, Script Includes, Business Rule execution order, GlideRecord/GlideAjax)
• Experience with scoped application development
• Familiarity with ITSM core tables (Incident, Task, SLA) and how SLA/stage logic is calculated
• Experience building or consuming REST integrations (JSON payload construction, authentication troubleshooting)
• Comfortable writing background/fix scripts for data diagnostics and remediation, with a 'diagnose before you fix' mindset
• Strong written communication skills - able to document technical root cause analysis clearly for both technical and non-technical audiences

Responsibilities

• Design, build, and maintain features within custom-scoped applications supporting multiple external agency clients
• Write and maintain Business Rules, Client Scripts, Script Includes, UI Policies, and ACLs, with attention to execution order and side effects (e.g., avoiding duplicate-insert issues in before insert rules)
• Configure and troubleshoot SLA definitions (task_sla), including investigating stage/state transition issues and running bulk data remediation scripts
• Build and maintain integrations between ServiceNow and external systems, including: Event Management integrations (e.g., Zenoss or similar monitoring platforms), REST-based integrations with tools like Power Automate/Power Platform, including OAuth troubleshooting, Scripted REST APIs exposed for consumption by external systems or AI/automation tools
• Investigate and resolve data integrity issues (e.g., stale sys_id references, orphaned or duplicate records) using diagnostic scripts before applying remediation
• Configure dynamic reference qualifiers, related lists, and dashboard/report widgets, including managing role-based access at scale
• Draft clear, client-friendly documentation and root cause analyses (RCAs) that translate technical platform behavior into language non-technical stakeholders can understand
• Support administration tasks across Windows and Linux environments as needed for integration and monitoring tooling
• Participate in Zurich (or current release) patching activities and help troubleshoot post-patch issues (e.g., Customer Service Portal search behavior)
