Senior Product Manager (Billing)

NMI is a company that empowers partners with innovative payment solutions, and they are seeking a Senior Product Manager focused on Billing & Invoicing. This role will own the strategy and execution of a unified billing approach across the product portfolio, improving billing accuracy and operational efficiency while collaborating with various teams to ensure successful delivery and customer satisfaction.

Responsibilities:

• Own the Billing & Invoicing strategy and roadmap for a unified billing approach across the product portfolio, covering fee calculation, invoicing, credits/adjustments, residuals and reconciliation
• Lead discovery across the payments ecosystem to gather insights from merchants/partners and internal commercial teams. Similarly incorporate competitive/market research and product insights to identify friction, risk, and growth opportunities
• Define and maintain clear product requirements for payments billing use cases, such as pricing and fee schedules, tiered/volume pricing, minimums, pass-through fees, commissions, one-time fees, credits/refunds, feature bundling, and exception handling
• Partner with Engineering to deliver the new billing engine and single customer billing view, ensuring a robust model that supports payments artefacts (e.g., transaction/event lineage, product/merchant hierarchy, and traceability from source events to invoice lines)
• Guide consolidation of existing billing workflows into the unified model, including migration planning, phased rollout, and cutover readiness, with a focus on billing continuity and customer impact
• Work closely with stakeholders to ensure correct application of tax rules, enabling compliant invoicing, accurate reporting, and clear auditability
• Encourage governance and controls that reduce commercial and financial risk such as pricing change discipline, approvals, audit trails, and tooling/monitoring to surface revenue leakage, and invoicing defects early
• Drive launches and adoption that include release planning, documentation, enablement for internal teams, and operational runbooks for billing cycles, exception management, and customer queries
• Monitor and improve outcomes using payments-relevant metrics such as billing accuracy, dispute/credit volumes, invoice timeliness, reconciliation variance, support contact drivers, and revenue optimization
• Act as the Billing domain SME, aligning stakeholders across Engineering, Finance, Sales, Legal/Compliance, and Marketing on changes that affect pricing, fees, customer communications, and financial reporting inputs
• Define and evolve hybrid billing capabilities - including SaaS subscriptions, usage-based models, and bundled offerings - ensuring the unified billing engine can support flexible pricing constructs and deliver clear, accurate, and explainable charges to customers

Requirements:

• Over five years experience as a Product Manager delivering end-to-end outcomes (discovery, delivery, launch, iteration) in a cross-functional environment
• Strong domain experience in payments and billing, such as merchant acquiring/gateway models, transaction-based fees, residuals/commissions, blended/interchange-plus pricing constructs, partner/channel billing, and invoicing/reconciliation workflows
• Track record leading complex platform initiatives (consolidation, migrations, or core workflow redesigns) in environments where accuracy, auditability, and operational resilience are critical
• Strong technical fluency: able to work with Engineering on APIs, integrations, data models, data analysis, event style thinking, and non-functional requirements (reliability, scalability, security, observability)
• Data-driven approach to diagnosing and preventing billing issues typical in payments, and to measuring product performance
• Excellent stakeholder management and communication skills, with experience partnering across Engineering, Finance, Support, Legal/Compliance, Sales, and partner facing teams
• Strong written communication skills for PRDs, user stories, release notes, enablement materials, and operational documentation
• Bachelor's degree (or equivalent practical experience) in a relevant field (e.g., business, economics, computer science, engineering)
