Project Context
The client operates a custom-scoped ServiceNow application supporting global mobility programs and managing employee international assignments. The platform is business-critical and widely adopted internally.
As ServiceNow and HR Service Delivery (HRSD) capabilities have evolved, the organization is initiating a strategic modernization to further enhance value and long-term scalability.
The initiative focuses on:
Aligning UX with current ServiceNow standards
Strengthening architectural alignment with best practices
Increasing integration with the native HRSD module
Improving maintainability and upgrade safety
The goal is to create a more unified HR experience, reduce long-term support overhead, and position the platform as a seamless extension of HRSD.
This phase requires strong architectural leadership to define the target state and guide structured implementation.
The Role
This is an architect/senior-level consulting engagement, focused on architecture leadership rather than hands-on feature development.
As an architect, you will define the structural direction of the modernization effort and guide internal ServiceNow developers through execution.
Team: You will collaborate with the Product Owner, 2 Business Analysts, 2 ServiceNow Developers, Mobility SMEs, and a Project Manager, providing architectural leadership while the internal team leads implementation.
