Job Description

About the role

As Product Manager for Fintech, Billing & Accounting, you'll own the strategy and roadmap for our payments and money-movement stack-card/ACH acceptance, merchant onboarding & underwriting, tokenization, billing, refunds/reversals, settlements, reconciliation, and financial reporting. You'll turn complex regulatory and accounting needs into elegant, scalable products that our customers love-and you'll drive them from PRD to GA with urgency and precision.

What you'll do
  • Own the platform. Define and drive the roadmap for payments, billing, invoicing, taxation, refunds, chargebacks/disputes, settlements, and reconciliation/ledgering.

    Discover & ideate. Run customer interviews, analyze data, and synthesize insights into problem statements, hypotheses, and measurable outcomes.

    Ship with clarity. Author crisp PRDs, acceptance criteria, and success metrics; manage the backlog and trade-offs across scope, quality, and timelines.

    Partner to execute. Lead cross-functional squads (Engineering, Design, Data, Risk, Compliance, Support, Onboarding, Sales/Marketing) to ship features on time.
  • Scale the rails. Improve authorization success, autopay reliability, retries, and failure handling; streamline merchant onboarding/KYB and terminal/hosted-pay flows.

    Make finance right. Deliver robust reconciliation flows (reports/webhooks), month-end close support, AR/AP/aging views, and revenue recognition support.
  • Measure & iterate. Instrument adoption and reliability; run experiments; track forecast vs. actuals; drive continuous improvements post-launch.
  • Evangelize. Enable Sales, Marketing, and Support with collateral, demos, playbooks, and release notes; be the voice of the product internally and with customers.
Minimum qualifications
  • 5+ years in a B2B Product Manager/Product Owner role or similar role.
  • 2+ years building or implementing financial system software (fintech, billing, payments, accounting, finance, or ERP).
  • Working knowledge of accounting principles (invoicing, revenue recognition basics, AR/AP, reconciliation).
  • Ability to write moderately complex SQL (joins, CTEs, window functions for validation/analysis).
  • Functional Excel skills (PivotTables, VLOOKUP/XLOOKUP, formulas).
  • Strong written and verbal communication; comfortable leading roadmap, trade-offs, and stakeholder alignment.
Preferred qualifications
  • Experience with payment processors/gateways , tokenization, PCI/SOC2, chargebacks/disputes, ACH/NACHA, and settlement/funding flows.
  • Background in billing systems (proration, cycles, credits/refunds, taxes) and financial data pipelines (webhooks, SFTP reports, reconciliation).
  • Familiarity with terminal/hosted payments and in-product payments.
  • Exposure to GAAP nuances for SaaS/subscription products and month-end close processes.
