The Opportunity

We’re looking for a Senior Product Manager with a deep understanding of payments and a passion for building partner-friendly APIs to join our growing product team. You’ll work directly with the Chief Product Officer and cross-functional partners to define, build, and scale our payments capabilities and integration frameworks — enabling a new generation of third-party applications to connect and transact securely.

This is a highly visible, high-impact role with the opportunity to shape our payments strategy and expand the reach of the Ninth Wave platform.

What You’ll Do

• Own the product lifecycle for our payments APIs — from discovery and design to launch and continuous improvement.
• Collaborate with engineering and design to define technical requirements, API schemas, and integration flows.
• Partner with external fintechs and internal stakeholders to understand pain points and build features that scale.
• Drive integration readiness and enablement, including documentation, testing tools, and onboarding frameworks.
• Serve as the internal subject matter expert on payment flows, standards (e.g. ACH, RTP), and best practices.
• Identify opportunities to simplify integration experiences and reduce time-to-market for third-party developers.
• Leverage AI tools to accelerate research, documentation, and technical understanding where applicable.
• Complies with the company in-office policy
• Collaborate in-person with teams at our New York City office to drive initiatives
  
  

• 5+ years of product management experience, ideally in fintech, banking, or payments.
• Strong understanding of payments systems (e.g., ACH, wire, RTP, card rails), payment operations, and API design.
• Experience working with or building for third-party developers and partners.
• Familiarity with OAuth, token exchange, and developer onboarding flows is a strong plus.
• Technical fluency — comfortable working through API specs, integration edge cases, and data models with engineers.
• Excellent written and verbal communication skills.
• Proactive, self-directed, and comfortable navigating ambiguity in a fast-paced environment.
• AI fluency a plus — bonus points if you actively use LLMs to supercharge your workflow.
  
  

• Shape the future of a platform critical to the open banking ecosystem.
• Join a small, focused team with strong leadership and a clear mission.
• Own a critical domain — your work will be foundational to our partner success and product growth.
• Work at the intersection of finance, data, and technology.
• Competitive compensation, equity, and benefits in a high-impact role.
