Systems Implementation Specialist (SIS) - Benefits & Payroll

Role: Systems Implementation Specialist (SIS)

The Systems Implementation Specialist (SIS) is a
cross-functional, client-facing role responsible for implementing and
supporting client benefit administration and HR technology platforms. This role
works daily across the Benefits, Payroll Services, and HR Consulting teams and
is expected to move fluidly between platforms and disciplines as client needs
require. The SIS is not a single-platform specialist: success in this role
depends on the ability to configure, troubleshoot, and support multiple systems
in parallel, including Employee Navigator, PrismHCM, Rippling, and ADP
Workforce Manager, while coordinating closely with internal teams and external
vendors to deliver accurate, on-time results.

Cross-Functional Expectations

This role sits at the intersection of Benefits, Payroll, and HR
Consulting. The SIS is expected to:

•        Operate as a connective
resource across teams, translating requirements between Benefits, Payroll, and
HR Consulting so implementations stay aligned end to end.

•        Partner with Payroll Services
on data setup, deductions, and integration timing so benefit and payroll
systems stay in sync.

•        Support HR Consulting on ATS,
Performance Management, and LMS rollouts when projects overlap with benefits
implementations.

•        Flex across concurrent client
projects and platforms, reprioritizing quickly as deadlines or vendor issues
shift.

•        Escalate cross-team
dependencies proactively, rather than waiting for issues to surface downstream.

Essential Duties and Responsibilities

The essential functions include, but are not limited to, the
following:

•        Benefits Administration
Platform Implementation & Support (Primary Focus)

•        Serve as lead implementer for
Employee Navigator, the organization's primary benefit administration platform,
from initial build through go live.

•        Configure carrier and payroll
integrations via XML, API, and EDI, and troubleshoot discrepancies through
resolution.

•        Provide ongoing support for
annual open enrollment, mid-year changes, and platform updates.

•        Maintain working proficiency in
other client benefit administration systems as client platforms vary.

Multi-Platform Client Systems Support

•        Serve as a knowledgeable point
of contact for client companies working across platforms, supporting
configuration, troubleshooting, and data accuracy on these platforms.

•        Coordinate timelines across
systems and ensure all client and vendor deliverables are met within
established deadlines.

•        Collect, format, and upload
client data across platforms, ensuring accuracy and consistency regardless of
source system.

•        Adapt quickly to additional
client platforms outside this list as the client base evolves.

•        Escalate complex issues to the
appropriate internal team while maintaining client satisfaction.

HR Module Implementation Support

•        Facilitate implementation of HR
modules within client HRIS systems, including Applicant Tracking Systems (ATS),
Performance Management, and Learning Management Systems (LMS).

•        Coordinate with HR Consulting
to ensure HR module rollouts align with parallel benefits implementations.
