Product Manager – Payments

B-Stock is the world's largest B2B re-commerce platform, connecting sellers and buyers of returned, trade-in, and overstock inventory. The Product Manager for Payments will own payment infrastructure and integrations, working cross-functionally to define requirements and improve payment processes across the marketplace.

Responsibilities:

• Lead product work across payments: Drive discovery, prioritization, and execution for payment systems including invoicing, disbursements, automated billing, and payment method infrastructure — while staying flexible to take on adjacent product areas as needs evolve
• Lead third-party integrations: Manage the full lifecycle of integrations with payment vendors such as Stripe, GetBalance, NetSuite, and future partners — from discovery and scoping through launch and iteration
• Drive key metrics: Define, track, and continuously improve payment-related KPIs including Time to Pay, payment success rates, and failure/chargeback rates
• Define requirements: Translate complex financial and technical requirements into detailed PRDs, user stories, and acceptance criteria that engineering teams can execute with minimal back-and-forth
• Identify and mitigate risk: Proactively surface and address risks related to fraud, payment compliance, and reconciliation gaps before they become customer-facing issues
• Partner cross-functionally: Collaborate closely with engineering, finance, operations, and account management to resolve integration challenges and ship reliable payment features
• Build payments fluency: Develop strong working knowledge of payment flows, reconciliation processes, and vendor capabilities to effectively represent the domain in cross-functional discussions
• Support enterprise clients: Partner with account management and engineering to manage payment-related client migrations and technical onboarding with minimal disruption
• Communicate with stakeholders: Clearly articulate product strategy, tradeoffs, and feature rationale to leadership, engineering, and client-facing teams across all areas you support
• Stay current: Keep up with product best practices, payment industry trends, emerging vendors, and relevant regulatory developments to continuously improve the areas you own

Requirements:

• 3+ years of product management experience, with at least 2 years focused on payments, fintech, or financial infrastructure, preferably within a B2B, SaaS, marketplace, or e-commerce environment
• BA/BS/MS degree in Business, Computer Science, Engineering, Finance, or a related field
• Demonstrated history of shipping payment features or integrations with measurable business impact
• Proficiency in product management and collaboration tools; comfort working with technical documentation and API-level concepts
• Experience working on or alongside payment systems — including concepts such as ACH, wire transfers, credit card processing, net terms, automated billing, or reconciliation; depth in some areas is valued over breadth in all
• Hands-on experience managing third-party payment platform integrations such as Stripe, GetBalance, NetSuite, or comparable vendors
• Ability to read API documentation, understand system architecture tradeoffs, and collaborate closely with engineering teams on complex integration decisions
• Proficiency in defining KPIs, analyzing payment data, and using insights to drive prioritization and product decisions
• Strong ability to write detailed PRDs and manage technical backlogs with minimal oversight
• Comfortable working with cross-functional partners — finance, legal, operations — to identify and navigate fraud, compliance, and reconciliation considerations in complex B2B environments
• Excellent written and verbal communication for PRDs, stakeholder updates, and cross-functional alignment
• Comfortable leveraging AI tools — including Claude and Claude Code — to accelerate discovery, requirements writing, data analysis, and day-to-day product workflows; treats AI as a core productivity layer, not an afterthought
• Can work autonomously within a strategic framework, make sound product decisions, and deliver results consistently
• Experience with B2B marketplace, auction, or liquidation platforms
• Background in financial operations, ERP systems, or reconciliation workflows
• Familiarity with fraud detection tooling or risk management in payment ecosystems
• Exposure to logistics, supply chain, or fulfillment workflows — especially where they intersect with payment triggers, dispute resolution, or operational reporting — is a strong bonus
• History of improving payment-related KPIs through sustained product iteration
• Experience supporting enterprise client migrations involving payment system changes
• Familiarity with agile development processes and continuous delivery
