DayOne Datacenter is looking for a Business Internal Controls Manager to strengthen and independently assess controls across its corporate and operational functions. This is a hands-on audit role within the second line of defence (LoD2), covering financial controls, business process controls, and entity-level controls across multiple functions and markets.

The role requires someone who can move fluidly between finance, procurement, HR, and operational processes — assessing control design, testing operating effectiveness, and producing findings that are clear, credible, and actionable. Candidates with a Big 4 or strong internal audit background and multi-entity or regional exposure will be at a significant advantage.

Control Testing & Business Process Audit

• Plan and execute risk-based control reviews across key business processes including Procure-to-Pay (P2P), Order-to-Cash (O2C), Record-to-Report (R2R), payroll, fixed assets, and vendor management.
• Assess the design adequacy and operational effectiveness of financial and business process controls across corporate and operational entities.
• Conduct walkthroughs, sample testing, and substantive procedures to evaluate whether controls operate as intended.
• Work with Internal Audit/SOX audit team on validating/assessing audit findings with clear root cause analysis, risk ratings, and management implications — producing work that is ready for senior review without further rework.
• Track remediation actions to verified closure, challenging management where fixes are superficial or incomplete.

Financial Controls & ICFR Assurance

• Support the assessment of internal controls over financial reporting (ICFR), identifying gaps and weaknesses that could affect the integrity of financial statements.
• Evaluate journal entry controls, reconciliation processes, period-end close procedures, and financial reporting workflows.
• Identify control deficiencies, assess their severity, and escalate material issues to the Head of Internal Controls.

Risk & Control Monitoring

• Maintain and update the business process control risk register, reflecting findings, environmental changes, and remediation progress.
• Identify patterns and systemic issues across functions or entities that warrant escalation or deeper review.
• Contribute to the development of Key Control Indicators (KCIs) to enable continuous monitoring of high-risk control areas.

Stakeholder Engagement

• Engage process owners and business unit leads across functions to gather evidence, discuss findings, and agree on credible remediation plans.
• Maintain LoD2 independence and objectivity throughout engagements, including when findings are contested.
• Support external auditors and regulatory reviewers with relevant documentation, walkthroughs, and control evidence.

Reporting

• Prepare concise, well-structured control assessment reports for the Head of Internal Controls and senior management.
• Contribute to periodic reporting on the state of business process and financial controls across the organisation.

Education & Experience

• Bachelor's degree in Accounting, Finance, Business, or a related discipline.
• 3–5 years of relevant experience in external or internal audit, internal controls, or assurance — with a preference for candidates who have spent time in a Big 4 or reputable audit firm.
• Exposure to multi-entity, multi-market, or regional environments is strongly preferred.
• Experience auditing business processes across finance, procurement, HR, or operations is essential.

Technical & Functional Competencies

• Strong grounding in audit methodology — risk assessment, control design evaluation, testing, sampling, and findings documentation.
• Sound understanding of financial controls and ICFR concepts, including journal entry testing, reconciliation controls, and segregation of duties.
• Familiarity with control frameworks such as COSO or equivalent.
• Proficiency in working with ERP systems (SAP, Oracle, or equivalent) in an audit context is an advantage.

Skills & Attributes

• Rigorous and detail-oriented, with the discipline to produce well-evidenced, audit-quality work.
• Independent thinker — able to form and defend a view based on evidence rather than stakeholder preference.
• Strong written communication, capable of producing findings reports that are specific, clear, and ready for senior consumption.
• Organised and methodical, able to manage concurrent audit workstreams across functions without losing quality.
• Collaborative but firm — able to work constructively with business stakeholders while maintaining LoD2 objectivity.

Certifications (Preferred)

• CIA (Certified Internal Auditor) or actively pursuing
• CPA / ACCA / CA (or equivalent professional accounting qualification)
• CISA (Certified Information Systems Auditor) is an advantage
