Software Engineer, Monetization Infrastructure (SF/Seattle)

About the Team

The Monetization team is a new cross-functional group working across engineering, product, research, and design to build the foundational systems that will help OpenAI scale access to intelligence responsibly. Our mission is to develop user-first, privacy-preserving monetization products—including next-generation ads experiences—that strengthen user trust, unlock economic opportunity, and support OpenAI’s long-term innovation.

Monetization plays a critical role in enabling OpenAI to continue pushing the boundaries of AI capabilities while ensuring the benefits of AGI are broadly shared. We believe monetization must be aligned with user value, uphold rigorous privacy and safety standards, and sustain a healthy ecosystem of developers and businesses.

This team operates in a greenfield environment and moves quickly through prototyping, experimentation, and iterative deployment. We partner closely with Product, Design, and Research to bring research breakthroughs into real-world systems at global scale.

About the Role

We’re looking for an experienced Software Engineer to help build the core infrastructure behind OpenAI’s monetization and ads systems. In this foundational role, you’ll architect and implement distributed systems that power OpenAI’s monetization stack—focusing on reliability, performance, privacy, and large-scale operation.

You’ll work across backend, systems, and platform layers to define and implement 0→1 infrastructure, partnering closely with Product, Design, and Research to shape the future of monetized AI experiences. Your work will enable both internal and external teams to build on safe, scalable, and robust monetization primitives.

This role is exclusively based across our San Francisco & Seattles sites. We offer relocation assistance to new employees.

In this role, you will:

• Design and build the foundational backend and infrastructure powering OpenAI’s monetization and ads systems

• Architect large-scale distributed systems that meet strict requirements for reliability, privacy, security, and performance

• Develop APIs, infrastructure services, and internal platforms that support ads creation, delivery, measurement, and optimization

• Work closely with Product, Research, and Design to translate requirements into scalable technical solutions

• Drive 0→1 infra development through rapid prototyping, experimentation, and iterative improvements

• Contribute to the long-term technical strategy and roadmap for the monetization infra stack

• Ensure high engineering rigor through excellent testing, documentation, observability, and operational best practices

• Build for safety, privacy, fairness, and policy alignment from first principles

• Collaborate across engineering orgs to ensure the infra layer is flexible, performant, and resilient

You might thrive in this role if you:

• Have 10+ years of experience building and operating large-scale distributed systems

• Have experience designing mission-critical systems with demanding reliability, performance, and correctness requirements

• Think in systems—architecture, data flows, operational concerns, observability, and long-term maintainability

• Are comfortable defining technical direction in ambiguous 0→1 environments

• Enjoy working cross-functionally to shape product requirements and system capabilities

• Communicate clearly, reason holistically, and make decisions grounded in user needs and long-term system health

• Bonus: Experience in ads systems, marketplaces, AI/ML infra, or other monetization-intensive domains
