Moniepoint

Who we are Moniepoint Inc. is Africa’s all-in-one financial platform, helping 20 million businesses and individuals access seamless payments, banking, credit, cross-border, and business management tools each month.  As Nigeria’s largest merchant acquirer, we power most of the country’s point-of-sale (POS) transactions. Through our subsidiaries, Moniepoint Inc. processes over $250 billion in digital payment transaction value annually. About the role At Moniepoint, product management blends entrepreneurial drive, deep customer insight, and modern technology to solve the toughest problems in the service of powering the financial ambitions of millions across Africa. Over the years, our product craft - the operating system for how products are envisioned, built, launched, and run - has been shaped and refined by the core practices of leading tech companies, while staying true to the unique DNA that has made Moniepoint one of Africa’s fastest-growing companies.  At the core of this craft are our Product Managers: outcome-driven builders who live and breathe the realities, challenges, and dreams of our customers. They thrive in complex, fast-moving environments and partner deeply with engineering, design, and cross-functional teams to build products grounded in simplicity, trust, and delight from day one. They challenge the status quo - wherever it originates - and hold a high bar for product quality and execution excellence, starting with themselves. What you’ll do * Own and drive outcomes anchored in metrics and aligned with company OKRs. * Know your domain in depth: business, product, operations, customers, market, competitors, and risk/regulation. * Maintain a roadmap that balances near- and long-term priorities, and the right mix of growth levers, technical investments, and risk/regulatory requirements. * Leverage ongoing customer discovery, product analytics, and a range of experimentation techniques to validate assumptions and refine product direction and priorities. * Break down ambiguous, complex problems into clear proposals, actionable plans, and structured tradeoff scenarios and recommendations. * Pairs business acumen with a strong product, design, and technical mindset - ideally with true fluency in technical concepts, even without an engineering degree. * Dive beyond dashboards and interrogate the data directly. Build your own queries and analyses to validate hypotheses, stress-test intuition, and monitor early product signals. * Own the product’s written backbone: from one-pagers and PRDs to GTM plans, release scopes, and user stories. * Cultivate relationships with customers, teams, stakeholders, and leaders to ensure product direction is clearly communicated, aligned, and grounded in real-world context. * Hold a high bar for ownership, decision-making rigor, product quality, and execution excellence across teams and key partners. What you need to succeed * Bachelor’s degree (strong preference for candidates with degrees in a technical field) * 8+ years of relevant experience in technology companies, including 5+ years owning and driving products end-to-end as a Product Manager. * Track record of driving measurable outcomes tied to OKRs, shaping product direction, and converting complexity and ambiguity into high-value opportunities. * Deep customer empathy and the ability to synthesize qualitative and quantitative insights to build products that truly delight users. * Known for driving product velocity while upholding high standards of execution excellence, product quality, and risk mitigation. * Strong analytical skills across metric design and monitoring, funnel analysis, and evidence-based prioritization. Hands-on SQL experience is highly desirable. * Technical fluency to dive deep into system architecture, APIs, data flows, and tradeoff discussions with engineers. * Exceptional communication skills, both written and verbal, especially in executive-level and cross-functional settings. * High autonomy, sound judgment, resilience, and ability to thrive in a fast-paced, high-stakes environment. What sets you apart * Domain experience (where applicable- to be advised on a case-by-case basis). * Experience building, launching, and scaling fintech products. * Experience building products from zero-to-one or shaping entirely new product lines. What you’ll get * 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. What to expect in the hiring process * Application Review: Initial evaluation of your background, product experience, and evidence of solving problems and driving outcomes. * Preliminary phone call with recruiter: Discuss your background, motivations, and the context and scope of the role. * Interview with the Hiring Manager: Assess your experience building products, including relevant domain context where applicable. * Interview with a Senior Business Leader: Assess how you think and act as a product and business operator in complex real-world scenarios. * Interview with the CPO (or Senior Product Leader): Assess your product management craft through past experiences and practical scenarios.
