Location: Solihull (Hybrid)

Reports to: Enterprise Architect

Role Overview

We are seeking an experienced SuccessFactors Solution Architect to join our ERP programme on a 6-month contract.

• Support ongoing development of the SuccessFactors functional solution, ensuring it is standardised, scalable, adaptable, and sustainable.
• Oversee detailed fit/gap, configuration, and parameterisation of approved template extensions/localisations.
• Ensure functional stream documentation supports continuous knowledge transfer.

• Actively participate in Change Control Board (CCB) meetings, providing recommendations for architecture decisions and technology direction.

• Serve as a key stakeholder for any subsequent changes arising from workstream decisions once scope and design are agreed.
