System Software Engineer, Integrity

About the Team

The Integrity team at OpenAI is dedicated to ensuring that our cutting-edge technology is not only revolutionary but also secure from a myriad of adversarial threats. We strive to maintain the integrity of our platforms as they scale.

The Integrity team is at the front lines of defending against financial abuse, scaled attacks, and other forms of misuse that could undermine the user experience or harm our operational stability.

About the Role

At OpenAI, our mission is to advance AI in a way that is safe, reliable, and aligned with broad societal values. We are seeking a Software Engineer who will work at the intersection of large-scale distributed systems and security infrastructure. In this role you will build, scale, and defend critical backend services : powering training infrastructure at scale and protecting the platform from misuse, adversarial behavior, and systemic abuse. Your work will ensure both performance, reliability, and safety across our systems.

In this role, you will :

Design and maintain systems and frameworks that enable effective identification and assessment of emergent risks (e.g., reasoning, instruction-following, or agentic behavior) supporting security and safety teams in catching issues before they lead to external incidents.

Architect and build scalable, resilient backend systems and internal tooling to support a lean, high-efficiency operating model

Proactively probe systems to uncover latent bugs and failure modes before they manifest in production

You might thrive in this role if you :

Have at least 5 years of software engineering experience working on distributed systems, platforms, or infrastructure.

Love figuring out how systems work and continuously come up with ideas for how to make them faster while minimizing complexity and maintenance burden

Are deeply versed in potential failure modes of AI and ML systems (e.g. sycophancy, adversarial inputs, jailbreaks, harmful outputs) and have experience detecting or mitigating them

Enjoy working adjacent to research teams and translating novel technical ideas into production-grade, safe systems - rather than operating purely in product or commercial domains

Proactively investigate complex systems to uncover bugs, edge cases, and unexpected failure modes, using insights to strengthen reliability.
