Product Analyst / Associate Product Manager - Payments / Integrations

KabuK Style is building the next generation infrastructure for the global travel industry.

Our flagship product, HafH, already connects over 30,000 accommodations across 130+ countries and serves a rapidly growing international customer base. As we scale, we are developing a new B2B platform that powers travel distribution, supplier integrations, pricing optimization, and booking infrastructure for partners around the world.

We are looking for a Product Analyst / Associate Product Manager to join our Platform team and work on some of the most critical parts of our system: API integrations, payment flows, and billing/invoicing services.

This is a hybrid role combining data analysis and product ownership. You will not only analyze data and surface insights, but also help define product behavior, shape requirements, and drive improvements across the platform.

You will start as an individual contributor, working closely with Product, Engineering, and Finance. Over time, you will take on increasing ownership of specific product areas and play a key role in shaping how our platform evolves.

We care more about your ability to work with complex systems and data than specific titles or years of experience.

• API Integrations & Platform Data
• Analyze performance across supplier APIs (availability, pricing, content)
• Identify inconsistencies across sources and help define normalization logic
• Work with engineering to improve reliability, latency, and error handling
• Support development of a unified data model across integrations
• Payments & Billing Systems
• Help define and optimize:
• Payment flows (success/failure handling, retries, edge cases)
• Billing cycles (weekly, bi-weekly, monthly invoicing)
• Credit lines, limits, and risk controls
• Analyze:
• Payment success rates and failure patterns
• Invoice accuracy and discrepancies vs supplier data
• Refunds, chargebacks, and reconciliation gaps
• Partner with Finance to ensure product logic aligns with accounting requirements
• Product Ownership (Core to This Role)
• Own specific problem areas within:
• API integrations
• Payments
• Billing and invoicing
• Translate business and financial requirements into product requirements
• Define metrics, success criteria, and edge cases
• Work with engineering on system behavior, data flows, and implementation tradeoffs
• Contribute to roadmap planning and prioritization
• Analytics & Decision Support
• Define and track KPIs across platform services
• Build dashboards and monitoring for system and business performance
• Move from data → insight → decision → product improvement
• Support experiments (A/B testing, pricing, flow optimization)
• Cross-functional Collaboration
• Work closely with:
• Product Managers
• Engineers
• Finance and Accounting
• Business and Operations teams
• Translate complex data into clear, actionable insights

• Build a strong understanding of:
• API integrations and data flows
• Payment and billing architecture
• Define and track key metrics for at least one core area
• Identify and help resolve data inconsistencies or system gaps
• Contribute to product decisions with clear, data-backed insights

This role is not limited to the responsibilities outlined above. As an early member of the Platform team, your scope will evolve based on business needs, platform maturity, and your strengths and interests.

You may have the opportunity to contribute across additional areas such as:

• New platform services and product initiatives
• Process and system design improvements
• Cross-functional strategic projects

We value individuals who are comfortable operating in dynamic environments and are excited to take on new challenges as the platform grows.

• Build and shape a next-generation travel platform (B2B2B SaaS)
• Work on complex, high-impact systems across global inventory, pricing, and financial infrastructure
• Gain exposure to both product and analytics career paths
• High ownership, fast learning, and direct impact on core platform systems
