Shield AI is seeking a senior Solutions Architect – Human Capital Management (HCM) to serve as the functional and technical authority across Shield AI’s dual HCM landscape: UKG and Oracle Fusion HCM. Oracle Fusion HCM is being implemented for Time and Labor (OTL) and Absence Management, while the remainder of core HCM — recruiting, onboarding, core HR, talent, and workforce lifecycle — runs on UKG. This role owns the architecture, configuration, and continuous improvement of both platforms and the data/process seams between them.

This is a hands-on, business-facing, and cross-functional role. Payroll and Time Management are owned by Finance; the remaining HCM functions are owned by People Experience (PX). The Solutions Architect – HCM is expected to bridge these two organizations, translating each group’s requirements into a single, coherent HCM systems strategy rather than two disconnected roadmaps — and to be the go-to resource for any HCM process change that touches either platform.

For medium-complexity projects, this person configures Oracle Fusion HCM (OTL, Absence Management) and partners directly with UKG administrators/the UKG platform team to implement changes. For large, complex initiatives spanning both platforms, this person leads solution design and partners with Shield AI’s implementation partner to deliver, while remaining the accountable architect and the unifying voice across Finance and PX.

What you'll do:

Cross-Platform Strategy & Business Partnership

Designs and delivers technical solutions, creates detailed solution designs, specific integration points, and selects appropriate tools and frameworks. Collaboration with developers and engineers to implement solutions, conducts technical reviews and resolves design challenges.

Documents architectures, provides technical guidance during development, and ensures solutions adhere to performance, security, and interoperability requirements. Prototypes new approaches and evaluates emerging technologies for project suitability.

Serve as the primary systems point of contact and trusted advisor for both Finance (Payroll, Time Management) and People Experience (core HR, talent, recruiting, workforce lifecycle) on HCM process design and system capability questions.

Define and maintain a unified HCM systems strategy and target-state architecture spanning UKG and Oracle Fusion HCM, ensuring Finance and PX are working from one coherent roadmap rather than parallel, conflicting plans.

Act as the lead advocate for both business partner groups in all HCM-related discussions, ensuring Finance’s payroll/time requirements and PX’s workforce/talent requirements are each represented in solution design.

Become the go-to resource for any proposed HCM process change, evaluating impact, feasibility, and fit across both platforms before implementation — including which system of record should own a given data element or process step.

Facilitate alignment between Finance and PX when priorities, timelines, or system ownership questions conflict, acting as the neutral, technically credible tie-breaker.

Hands-On Configuration & Delivery

Directly configure Oracle Fusion HCM for Time and Labor (OTL) and Absence Management — time entry rules, accrual plans, approval workflows, and eligibility/validation rules — for medium-sized projects, enhancements, and break/fix work.

Partner closely with UKG administrators and the UKG platform/support team to scope, configure, and validate changes to core HR, recruiting, onboarding, and talent processes in UKG.

Author functional design documents, configuration workbooks, test scripts, and process/procedure documentation covering both platforms and their integration points.

For large or highly complex initiatives, define solution architecture and requirements across both platforms, then partner closely with the implementation partner to execute — remaining accountable for solution quality, business fit, and knowledge transfer.

Participate in and help lead workshops, fit-gap sessions, and design reviews with Finance, PX, and implementation partner teams.

Platform Ownership & Boundary Management

Own the functional architecture of the UKG-to-Oracle Fusion HCM boundary, ensuring a clean, well-documented system-of-record model: UKG for core HR/talent/workforce lifecycle, Oracle Fusion HCM for OTL and Absence Management, and Finance-owned Payroll and Time Management processes downstream.

Maintain the master data and employee lifecycle data flow across UKG, Oracle Fusion HCM, and Payroll, avoiding duplicate data ownership, conflicting employee records, or process gaps across systems.

Track the Oracle Fusion HCM implementation roadmap (OTL and Absence Management) and ensure it remains architecturally aligned with UKG’s core HR data model and Finance’s payroll processing calendar.

Advise Finance and PX leadership on long-term platform strategy questions, including future scope changes to what runs on UKG versus Oracle Fusion HCM.

Integrations

Design and help implement integrations between UKG, Oracle Fusion HCM (OTL, Absence Management), and Payroll/Time Management systems owned by Finance.

Define integration requirements, data mappings, and error-handling/reconciliation approaches in partnership with technical/integration teams, with particular attention to time and absence data feeding payroll processing.

Evaluate integration patterns (API, middleware, file-based) and recommend approaches appropriate to data volume, payroll-calendar timing, and criticality.

Support testing, cutover, and hypercare activities for integration-related changes, including payroll-cycle-sensitive releases.

Governance & Continuous Improvement

Maintain configuration standards, documentation, and change control discipline across both the UKG and Oracle Fusion HCM environments.

Identify opportunities for process simplification, automation, and improved data quality across the employee lifecycle, time/absence, and payroll handoff processes.

Stay current on both UKG and Oracle Fusion
