Workday Solution Architect

HRIS/HCM Enterprise Architect - HR Transformation - Freelance

We are supporting a major global transformation programme seeking an experienced HRIS/HCM Enterprise Architect to define the future architecture of a complex global HR technology landscape.

The ideal candidate will have strong Workday experience, although experienced HRIS/HCM Enterprise Architects from other enterprise platforms will also be considered.

This is a strategic architecture position focused on taking a holistic view of the HR ecosystem, defining the target application landscape and integration strategy, and providing architectural direction to delivery teams.

The Opportunity

The organisation is transitioning approximately 30 HR applications into a new operating landscape, with 70-80 applications requiring integration.

You will help define how these applications, platforms, integrations, data and infrastructure come together to create a scalable and sustainable future-state architecture.

Key Responsibilities

• Own the end-to-end HR architecture, covering Hire-to-Retire and Time-to-Pay.
• Define the target HRIS/HCM application and integration strategy.
• Architect integrations across 70-80 applications, including Finance, Payroll and Time Management.
• Take a holistic view of the wider HR application landscape and identify opportunities for rationalisation.
• Cover the broader HR ecosystem including Talent, Compensation, Benefits, Payroll, Time Management and Core HCM.
• Define integration patterns across APIs, Middleware, data and extended infrastructure.
• Establish architecture principles, standards and technology decisions.
• Provide technical direction and guidance to delivery teams responsible for implementation.
• Assess architectural risks, dependencies and technical debt.
• Produce clear architecture documentation and models using the C4 Model.
• Support the development of the long-term HR technology roadmap.

What We're Looking For

• Strong experience as an Enterprise Architect, HRIS Architect or HCM Architect.
• Workday experience is preferred, but strong experience across other enterprise HRIS/HCM platforms will be considered.
• Proven experience owning end-to-end Hire-to-Retire and Time-to-Pay architecture.
• Experience across complex, multi-application HR environments.
• Strong understanding of integration architecture, APIs, Middleware and enterprise applications.
• Experience integrating HR platforms with Finance, Payroll and wider corporate systems.
• Understanding of extended infrastructure, security and data architecture.
• Strong business acumen and ability to translate business requirements into practical architecture.
• Excellent stakeholder management skills across global, cross-functional teams.
• C4 Model architecture experience is required.

Why This Opportunity?

A chance to play a key architectural role in a large-scale global HR transformation, shaping the target HRIS landscape and integration strategy across dozens of applications.

The role is strategic rather than hands-on implementation focused - you'll define the architecture and provide direction, with dedicated delivery teams responsible for building and implementing the solutions.
