Role Overview

The Product Auditor provides independent assurance over the design, implementation, and operating effectiveness of product controls across payment, wallet, settlement, switches and other related products across the organisation

The role ensures that new and existing products are deployed with adequate financial, operational, security, and regulatory controls, safeguarding the organization against revenue leakage, settlement failures, regulatory breaches, and technology-driven risks.

The Product Auditor will independently evaluate product risk exposure and control maturity prior to scale.

Key Responsibilities 

Audit Universe & Risk-Based Planning

• Maintain a living Product Audit Universe covering all payment products, features, and integrations ranked by risk. 
• Own the annual Product Audit Plan, ensuring coverage is allocated dynamically based on risk ratings, product complexity, regulatory sensitivity, and change velocity.

Product Design & Control Assurance

• Review PRDs, business rules, and transaction workflows to identify logic gaps, unmitigated risk paths, and missing exception-handling routines before products reach production/go-live. 
• Analyse product path scenarios, verify Maker-Checker enforcement, and provide formal control design sign-off before any material release goes live.

Live Product Assessment ( Continuous Audit Review)

• Periodically assess live payment products to confirm they continue to operate within approved design parameters. 
• Detect configuration drift, identify silent divergence from original PRDs, and analyse live transaction data for emerging risk patterns.

Go-Live Readiness & Control Gate

• Execute mandatory pre-production Product Audit reviews as an independent control gate for all material releases. 
• Confirm reconciliation logic, exception queues, and fallback controls are tested and functional. 
• Escalate critical deficiencies with risk ratings and hold recommendations where a product is not safe to release.

Transaction Logic & Mathematical Integrity

• Interrogate the Fee Engine using SQL to mathematically prove that commissions, VAT, discounts, and splits are posted with complete precision. 
• Validate duplicate prevention mechanisms and ensure transaction integrity within complex, multi-step payment sequences, and test reversal, refund, and chargeback logic to confirm financial symmetry is maintained in every scenario.

Settlement & Ledger Integrity

• Trace fund flows, confirming continuous synchronisation between wallet sub-ledgers and the General Ledger. 
• Assess reconciliation logic for breaks and evaluate the authorisation, documentation, and reversibility of manual settlement overrides.

Product Change & Configuration Integrity

• Confirm that all product modifications: fee tables, routing rules, limit parameters passed through an approved change management cycle. 
• Identify silent changes made outside formal release processes and audit the integrity of product master data to ensure it is access-controlled, version-tracked, and consistent with approved product terms.

Vendor & Third-Party Product Risk

• Assess controls over vendor-managed product components, evaluate SLA performance against contractual commitments, and identify single-vendor dependency risks within critical payment flows. 
• Evaluate the organisation's ability to detect unilateral changes in third-party API behaviour, fee logic, or settlement processes.

Control Advisory & Stakeholder Engagement

• Engage product and engineering teams early in the design cycle to provide informal control advisory, reducing findings at the formal review stage without compromising independence. 
• Participate in design reviews and architecture discussions, and build a control-by-design culture across product teams. 

Incident Review, RCA & Regulatory Alignment

• Lead post-incident reviews for product failures,producing structured RCA reports that identify underlying logic failures, not just surface symptoms. 
• Assess corrective actions for adequacy and track findings to verify closure. 
• Ensure product logic complies with CBN guidelines, PCI DSS, and consumer protection obligations at the design level, and evaluate the regulatory impact of new features before release.

Reporting & Governance

• Prepare risk-rated audit reports for Executive Management and the Audit Committee, leading with findings, financial impact, and required action. 
• Maintain a Product Risk Register, deliver quarterly control maturity updates, and ensure governance bodies are never surprised by a product failure that was visible at the design or portfolio review stage.

About the role

At Moniepoint, data is the lifeblood of our financial operating system. The Head of Data Governance is a senior leadership role responsible for ensuring that this lifeblood is high-quality, secure, and accessible. You will architect and champion the enterprise-wide data governance framework, transforming how 13 million+ people’s data is managed and protected.
Reporting to the Head of Enterprise Data, you aren't just a policy writer; you are a cultural catalyst. You will lead a "virtual team" of Data Stewards across the company, ensuring that while they sit within diverse units like Finance or Sales, they operate with a unified, gold-standard approach to data accountability.

About You

The Architect: You don't just see data; you see the structures that make it reliable. You enjoy building blueprints that balance strict compliance with the speed required by a fast-growing fintech.
The Influencer: You excel in a "Hub and Spoke" model. You can lead and inspire teams that don’t report to you directly, turning departmental data stewards into a cohesive community.
The Tech-Fluent Leader: You speak "Engineering" as well as you speak "Business." You understand how to automate governance so it becomes a feature of the workflow, not a bottleneck.
Ethical Guardian: You are passionate about data privacy (GDPR/NDPR) and believe that responsible data management is a competitive advantage, not just a regulatory chore.

What you will get to do:

1. Strategic Leadership & Framework Design

• Governance Roadmap: Develop and execute a long-term strategy that aligns with Moniepoint’s mission to build the financial OS for emerging markets.
• Policy & Standards: Author and maintain global policies (Privacy, Retention, Naming Conventions) that are clear, actionable, and "Regular Guy" friendly.
• Operating Model: Define our domain-driven structure and clarify data ownership across the company to eliminate ambiguity.

2. Functional Leadership of the Stewardship Team

• Orchestration: Direct the strategic priorities of Business Unit Data Stewards, ensuring they have the tools and training to succeed.
• Community Building: Create a "Data Governance Academy" to onboard, certify, and mentor stewards across the organization.
• KPI Alignment: Set the functional goals that define what "good" looks like for data quality within each business unit.

3. Tech Stack & Automation Ownership

• Platform Strategy: Select and manage our governance platforms (e.g., Atlan, Collibra, or Microsoft Purview), ensuring they integrate seamlessly with our data lake.
• Metamodel Design: Configure tools to link business terms to physical technical assets, creating a transparent data lineage.
• Governance-as-Code: Partner with Data Engineering to automate quality checks and PII masking within the CI/CD pipeline.

4. Risk, Compliance & Culture

• Enterprise DQ Reporting: Build "Data Health Dashboards" for the Executive team to provide visibility into our data reliability.
• Change Management: Lead the cultural shift from "data is IT’s problem" to "data is a strategic business asset."
• Literacy Programs: Develop workshops to empower non-technical staff to read, interpret, and respect data.

Qualifications:

• Experience: 9+ years of leadership experience in Data Governance, Data Engineering, or Data Strategy within a high-growth environment.
• Technical Proficiency: Advanced SQL and Python skills are essential. You should be comfortable auditing a data platform directly and working with APIs for automation.
• Framework Expertise: Deep knowledge of modern data architectures (Data Mesh, Data Vault 2.0) and how to apply governance within them.
• Regulatory Knowledge: Intimate familiarity with NDPR, GDPR, and fintech-specific data regulations.
• Education: A Bachelor degree in Computer Science, Engineering, Mathematics, or a related quantitative field (or equivalent practical experience).

What Success Looks Like

• Initial 6 Months: A defined Data Governance roadmap is approved, and the first "Data Health Dashboard" is live for critical data elements.
• The 1-Year Mark: Every major business unit has a certified Data Steward, and automated lineage is active for our core financial products.
• Culture: Data Governance is no longer viewed as a "blocker" but as the foundation that allows our product teams to build faster and safer.
  

What we can offer you

• Culture - We put our people first and prioritise the well-being of every team member. We’ve built a company where all opinions carry weight and where all voices are heard. We value and respect each other and always look out for one another. Above all, we are human.
• Learning - We have a learning and development-focused environment with an emphasis on knowledge sharing, training, and regular internal technical talks.
• Compensation - You’ll receive an attractive salary, pension, health insurance, annual bonus, plus other benefits.
