- Enable rapid pricing and packaging experimentation by building flexible abstractions and APIs for new SKUs, plans, and monetization models.
- Build high-converting, localized payment experiences across geographies.
- Power builder monetization by creating payment rails for apps, Agents, subscriptions, and new monetization primitives.
- Partner with finance, accounting, and data teams on data specifications for accurate, auditable, and reliable financial data.
- Collaborate with external monetization and payments partners to accelerate execution.
- Create monitoring, observability, and feedback systems to proactively detect issues, resolve failures, and optimize performance across financial flows.
