Purpose of the Role

JLL's Enterprise Service Management (ESM) team is hiring a mid-to-senior Service Now ITAM Developer, based onsite in Mexico, to design, build, and roll out the Hardware Asset Management (HAM) Advanced and Software Asset Management Professional (SAM Pro) modules on JLL's Service Now platform for stakeholders across the enterprise. This role is accountable for hands-on configuration, scripting, and integration work that moves JLL's IT asset management capability from foundational tracking toward advanced, automated hardware lifecycle and software license management. This developer is expected to help transform ESM's asset management practice into a governed, value-generating capability
- one that gives the business trustworthy hardware and software data, defensible license-compliance positions, and measurable cost-avoidance outcomes, and that applies AI and agentic AI, where genuinely fit for purpose, to reduce manual asset-management effort rather than adding automation for its own sake.

Three key qualifications are necessary to be successful in this role: (1) strong automation and development skill, including coding ability for web applications,



to configure and extend Service Now's HAM Advanced and SAM Pro 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; and (3) critical thinking
- the ability to apply ITAM best practices and standards appropriately to JLL's business rather than adopting them by rote.

Partner with the CMDB Product Owner and ITSM Engineering Manager to align HAM/SAM configuration with the CMDB data model and platform governance standards. Data Integrity, Normalization & License Reconciliation Build and maintain hardware and software normalization and reconciliation logic so discovered assets and installations map accurately to hardware/software models, entitlements, and configuration items. Configure license metrics, entitlements, allocations, and publisher content to support accurate compliance positions and defensible audit responses.

Automation, Scripting & Integration Development Develop Business Rules, Client Scripts, UI Policies, Flow Designer flows, and Integration Hub spokes to automate ITAM workflows and reduce manual processing.

Apply modern web application development practice
- Java Script, Glide APIs, and related front-end/back-end skills
- to build custom Asset Workspace experiences, Service Portal pages, and portal-facing self-service capability for stakeholders. Manage update sets and code promotion from development through test and production, following ESM's release and change-management process. Monitor scheduled jobs and integration performance for HAM/SAM discovery, normalization, and reconciliation, troubleshooting probe, sensor, and MID Server issues that affect asset data quality. Stakeholder Enablement & Business Process Support Support software and hardware audit responses and cost-saving initiatives (e.g., license reharvesting, true-up avoidance), and provide stakeholder reporting on asset posture. Document configuration, processes, and known issues to a standard that supports handoff, audit, and ongoing maintenance by the wider ESM team.
