Senior Product Manager

We are seeking a Product Manager focused on Billing & Invoicing to own the strategy, roadmap, and delivery of a unified billing approach across our product portfolio whilst maintaining existing solutions. This role will lead the evolution of our billing capabilities through a new billing engine and a single customer billing view. You will be improving billing accuracy, invoice clarity, reconciliation outcomes, operational efficiency, and trust in billing data for both customers and internal teams.

As a Product Manager, you will apply strong discovery and product judgement to define what we build and why. This includes conducting market and competitive research, gathering voice-of-customer and stakeholder insights, identifying problems and opportunities, and translating them into a clear product strategy with measurable outcomes. You will partner closely with Engineering, Finance, Data, Customer Operations, Legal/Compliance, and Marketing teams to shape requirements, prioritize delivery, and manage trade-offs across customer experience, commercial needs, and risk and control considerations.

You will also drive end-to-end execution: defining and communicating releases, ensuring operational readiness, coordinating enablement and training, and supporting launches with clear documentation and stakeholder communications. The role includes guiding the consolidation of existing billing workflows into the unified model, defining migration approaches and sequencing, and monitoring performance post-launch to drive continuous improvement. Success will be demonstrated through measurable outcomes such as billing capabilities that enhance customer experience, limited billing exceptions and disputes, and a scalable foundation that supports future growth and evolving pricing models.

About Us

We enable our partners with choice, and challenge the one-size-fits-all approach to payment. You’ve probably used NMI in the last 24 hours without even realizing it. We’re the platform that powers success for innovative tech created by SMBs, entrepreneurs and fintech startups. We’re creative problem solvers who help visionaries smash through boundaries and think beyond what’s possible so they can think about what’s next. But we’re not just built for the tech savvy. We democratize the latest payments technology so that everyone can realize the benefits of easy payments across the full spectrum of commerce. We’re all about enabling more payments in more ways and more places.

We believe that having a diverse group of employees strengthens both our work and our workplace. We’re focused on making NMI more diverse and welcoming with initiatives like having a dedicated Diversity, Equity & Inclusion action group, diversity goals for hiring, anonymized resume screening, affinity groups such as our Women's network and LGBTQ+ Network, open forums for discussions on diversity and social justice, and measuring inclusion and belonging as part of our regular employee engagement surveys.

Key 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.
• Preferred: Bachelor’s degree (or equivalent practical experience) in a relevant field (e.g., business, economics, computer science, engineering).

We Offer:

• Competitive salary + bonus
