ServiceNow ITSM Developer Purpose of the Role JLL's Enterprise Service Management (ESM) team is hiring a mid-to-senior ServiceNow ITSM Developer, based onsite in Mexico, to design, build, and continuously improve the core IT service management process modules on JLL's ServiceNow platform — Incident Management, Problem Management, Change Enablement, Request Fulfillment, Service Catalog, and Knowledge Management — for stakeholders across the enterprise.
This role is accountable for hands‐on configuration, scripting, and workflow automation that keeps these core ITSM processes reliable, efficient, and aligned to ITIL practice as JLL's service volume and complexity grow.
This developer is expected to help transform ESM's core service‐management practice into a more automated, self‐service‐first capability — reducing manual triage and routing effort, applying AI and agentic AI to routine incident and request handling where genuinely fit for purpose, and building workflows and self‐service experiences that let employees resolve more issues on their own.
- (1) strong automation and development skill, including coding ability for web applications, to configure and extend ServiceNow's core ITSM modules; - (2)



ITSM/ITIL expertise at large‐enterprise scale, paired with a proven track record of using AI and agentic AI to modernize IT Service Management; - (3) critical thinking — the ability to apply ITSM/ITIL best practices and standards appropriately to JLL's business rather than adopting them by rote.
Key Responsibilities Incident & Problem Management Development - Configure and extend Incident Management — lifecycle, assignment and routing rules, major incident workflows, and SLA definitions — to match JLL's ITIL 4 practice.
- Configure and extend Problem Management, including the known‐error database and root‐cause workflows, to support proactive problem identification.
- Build and maintain Business Rules, Client Scripts, UI Policies, and Flow Designer flows that automate triage, categorization, assignment, and escalation.
- Partner with the CMDB Product Owner to use accurate CI relationships and impact data in incident and major‐incident triage.
Change Enablement & Release Workflow Development - Configure and extend Change Enablement — normal, standard, and emergency change types, risk assessment, approval workflows, and CAB scheduling — aligned to ITIL 4 practice and JLL's change‐freeze and blackout policies.
- Build automated risk‐scoring and approval‐routing logic that uses CMDB dependency data to assess change impact.




- Partner with the Change Enablement Process Owner to translate policy and governance requirements into platform configuration.
Request Fulfillment, Service Catalog & Knowledge Development - Design and build Service Catalog items, record producers, and order guides; configure Request Fulfillment workflows and approval routing.
- Build and maintain Knowledge Management configuration — article workflows, feedback, and knowledge‐in‐context — to support self‐service and agent efficiency.
- Build tailored Service Portal pages, widgets, and user experiences for request fulfillment and knowledge self‐service.
Automation, Scripting & Integration Development - Develop Business Rules, Client Scripts, UI Policies, UI Actions, and Flow Designer / Integration Hub flows across the core ITSM modules to reduce manual processing.
- Build and maintain integrations between core ITSM modules and third‐party or internal systems (e.g., monitoring, HR, telephony/chat) via REST/SOAP APIs.
- Manage update sets and code promotion from development through test and production, following ESM's release and change‐management process.
AI & Agentic Automation in Core ITSM - Implement ServiceNow's native AI agent and Now Assist capabilities for ITSM (for example, automated incident triage and summarization, resolution recommendations, and conversational self‐service for routine requests), applying guardrails and human‐in‐the‐loop review appropriate to the risk of each use case.
- Partner with the ITSM Engineering Manager on where agentic action is appropriate for incident and request handling and where it requires human review.
Standards, Governance & Continuous Improvement - Apply ITIL 4 service‐management practice pragmatically to JLL's specific scale, tooling, and risk
