Overview

Headfirst is delivering a major transformation programme to implement Workday Financials, replacing legacy finance systems across the organization.

This is a large-scale, complex implementation involving multiple system integrations, data migration, and full end-to-end validation of financial business processes across the record-to-report, procure-to-pay, and order-to-cash lifecycles, including general ledger, accounts payable, accounts receivable, fixed assets, banking, and integrations with downstream and third-party systems.

Role Purpose

The Test Lead will own the test strategy and lead a team of testers executing hands-on testing across Workday Financials and its integrated ecosystem.

• Work closely with Workday functional consultants, developers, integration teams, and third parties to support defect resolution
• Lead User Acceptance Testing (UAT), including defect triage, re-testing, and coordination with Finance business users
• Maintain clear, auditable test execution evidence and documentation, ensuring test governance standards are met
