The role

Summary

OpenAI's Revenue Platform team is seeking a full-stack engineer to build critical financial infrastructure and user experiences that power billing, payments, and revenue recognition across the company. The role involves designing scalable platform components, developing internal tools for finance teams, and collaborating cross-functionally to translate complex business requirements into durable platform primitives that support OpenAI's commercial growth.

Platform Development: Build and evolve shared full-stack platform components including APIs, data models, services, and UI primitives that power billing, subscriptions, usage-based pricing, and enterprise entitlements
Revenue Architecture: Design scalable, reusable revenue workflows and abstractions that other product teams can compose to launch new offerings without reinventing core billing logic
Cross-functional Collaboration: Partner closely with product, frontend, and backend engineers to deliver end-to-end revenue capabilities, ensuring platform components are intuitive to adopt and safe to extend
Internal Tool Development: Develop internal platforms and tools used by Finance, Accounting, Sales, Support, and Go-To-Market teams to manage, audit, and reason about revenue data efficiently
AI Integration: Build automation and AI-powered capabilities within the Revenue Platform to reduce manual work, surface insights, and improve operational decision-making
Technical Leadership: Help define the architecture, standards, and contracts for a shared revenue platform, balancing flexibility for product teams with correctness, reliability, and compliance
Requirements Translation: Collaborate cross-functionally to translate ambiguous commercial, financial, and operational requirements into durable platform primitives that scale with OpenAI's products and customer base
