Software Engineer, Scaled Abuse

ABOUT THE TEAM

The Applied team safely brings OpenAI's technology to the world. We released ChatGPT; Plugins; DALL·E; and the APIs for GPT-5, embeddings, and fine-tuning. We also operate inference infrastructure at scale. There's a lot more on the immediate horizon.

Our customers build fast-growing businesses around our APIs, which power product features that were never before possible. ChatGPT is a prime example of what is currently possible. We simultaneously ensure that our powerful tools are used responsibly. Safe deployment is more important to us than unfettered growth.

The Fraud Engineering team works within our Applied Engineering organization identifying and responding to fraudsters on our platform. We are looking for a software engineer with anti fraud & abuse experience to help architect and build our next-generation anti-fraud systems.

ABOUT THE ROLE

The Scaled Abuse team protects OpenAI’s products and customers by detecting, preventing, and responding to fraudulent and abusive behavior at scale. We build and operate the backend and data systems that power real-time detection, investigation workflows, and enforcement — balancing strong protections with a great user experience as the platform grows.

Our work sits at the intersection of engineering and abuse expertise: we partner closely with Trust & Safety, Security, and Product to understand emerging attack patterns, translate messy signals into clear system behavior, and continuously harden our defenses. The problems are dynamic and ambiguous by default, so we value engineers who can quickly dive into an unfamiliar codebase, develop strong intuition about how it works end-to-end, and propose pragmatic improvements that make the entire stack more resilient.

IN THIS ROLE, YOU WILL:

- Design and build systems for fraud detection and remediation while balancing fraud loss, cost of implementation, and customer experience

- Work closely with finance, security, product, research, and trust & safety operations to holistically combat fraudulent and abusive actors on our system

- Stay abreast of the latest techniques and tools to stay several steps ahead of determined and well resourced adversaries

- Utilize GPT-5 and future models to more effectively combat fraud and abuse

YOU MIGHT THRIVE IN THIS ROLE IF YOU:

- Have at least 5 years of software engineering experience in backend and data systems.

- Have at least 2 years experience in fraud or abuse analysis, investigation, and/or operations

- Can dive into our codebase, intuit how it works, and be able to have a strong intuition for suggestions that will lead us to a stronger engineering position.

- A voracious and intrinsic desire to learn and fill in missing skills. An equally strong talent for sharing that information clearly and concisely with others

- Are comfortable with ambiguity and rapidly changing conditions. You view changes as an opportunity to add structure and order when necessary

- Experience in Machine Learning techniques is a plus, but not required

Our tech stack

Our infrastructure is built on Terraform, Kubernetes, Azure, Python, Postgres, and Kafka. While we value experience with these technologies, we are primarily looking for engineers with strong technical skills and the ability to quickly pick up new tools and frameworks.
