• Build and scale an in-house revenue tool.
• Design and implement robust backend integrations that safely interact with order management, subscription, and fulfillment systems.
• Develop shared platform capabilities including internal authentication systems, event tracking frameworks, background jobs, and developer tooling.
• Productionize analytics models, optimization logic, and decision engines into user-facing software.
• Own projects end-to-end, from ideation and architecture to deployment, monitoring, and iteration.
• Partner cross-functionally with Product, Data, Growth, and Operations to ensure systems align with revenue and experimentation goals.
• Maintain high standards for performance, reliability, scalability, and developer experience.
