On behalf of Mercer, GT is seeking a senior ServiceNow Solution Architect to support a strategic modernization initiative.

About the Client

Mercer is a global consulting leader in advancing health, wealth, and career outcomes for organizations and individuals. Headquartered in New York City, Mercer operates in over 130 countries with more than 25,000 employees and 180+ office locations worldwide. As part of Marsh McLennan, Mercer provides data-driven insights and tailored solutions in areas such as HR transformation, compensation and benefits, workforce analytics, and employee experience.

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.

Involvement: Part-Time for 2 months, then on an hourly basis throughout the project (6–8 months)
