Role: Workday Solution Architect
Location: Hercules, CA(Onsite)
Experience Level: Senior / Expert (12+ years in HRIS/HR Technology, including 5+ years in Workday Architecture)
Function: HR Technology / Digital Transformation [SuccessFactors-to-Workday Feasibility Assessment & Strategic Roadmap]
Workday Solution Architect to lead a strategic assessment of migrating from SAP SuccessFactors to Workday. This role will evaluate the feasibility, business value, technical complexity, risks, and long-term implications of the proposed transformation across the enterprise HR technology landscape.
The architect will assess existing HR applications, business processes, integrations, data architecture, security, reporting, and third-party platforms to define future-state architecture options and a practical implementation roadmap. The role requires deep expertise in both SuccessFactors and Workday, strong enterprise integration capabilities, and the ability to translate complex technical findings into actionable business recommendations for senior leadership.
Key Responsibilities
Current-State Assessment: Analyze the existing SuccessFactors landscape, including Employee Central, Compensation, Performance, Goals, Succession, Calibration, Reporting, and Learning, along with connected HR applications and integrations.
Fit-Gap Analysis: Evaluate existing HR processes against Workday HCM, Talent, Compensation, Performance, and Reporting capabilities, identifying functional gaps, customization requirements, and opportunities for process standardization.
Solution Architecture: Develop future-state architecture options, defining application boundaries, integration patterns, technology dependencies, and opportunities to simplify the HR technology ecosystem.
Integration Strategy: Assess existing interfaces and classify them as retain, rebuild, or retire. Define the target integration architecture using Workday integration tools, enterprise middleware, APIs, and appropriate integration technologies.
Third-Party Application Assessment: Evaluate the impact of migration on payroll, time and attendance, recruiting, onboarding, Learning, and other connected platforms, recommending which applications to retain, replace, or integrate.
Data Migration & Governance: Define the migration strategy for employee data, historical and effective-dated records, data cleansing, archival, retention, reconciliation, and validation.
Security & Compliance: Assess role-based security, access controls, data privacy, GDPR, data residency, auditability, and regulatory requirements, including validated-system considerations where applicable.
Business Case & TCO Analysis: Develop comparative assessments covering implementation costs, licensing, integration, ongoing support, resource requirements, timelines, risks, and five-year total cost of ownership (TCO).
Risk & Feasibility Assessment: Develop a weighted evaluation framework, risk register, dependency analysis, and go/no-go recommendation supported by business and technical evidence.
Transformation Roadmap: Establish a phased implementation roadmap aligned with contract renewal dates, business-critical periods, organizational priorities, and other transformation initiatives.
Program Governance: Recommend appropriate governance, testing, validation, change management, stakeholder engagement, and implementation assurance strategies.
Executive Stakeholder Management: Present architecture options, trade-offs, business benefits, investment requirements, and recommendations to HR, IT, Finance, and executive leadership.
Technical Leadership: Collaborate with internal HRIS teams, integration specialists, vendors, and system integrators while providing architectural guidance and mentoring throughout the assessment.
