Software Engineer, Cyber Safeguards

We're looking for a senior, independent Software Engineer to lead the technical work behind cyber safeguard infrastructure in Preparedness. You'll bring production-grade engineering discipline to systems that support everything from cyber evaluations and safeguard research internally to enabling the safe deployment of capabilities externally, while working closely with researchers and security partners.

The Preparedness team is dedicated to addressing critical risks. Our work includes:

• Measurement: monitoring and predicting the evolving capabilities of frontier AI systems.
• Mitigation: keeping misalignment safeguards, alignment tools, and on track to adequately address extreme threats that might arise in the future.
• Coordination: setting mitigation targets by maintaining OpenAI's preparedness framework, and partnering with other staff to achieve these targets.

In this role, you'll:

• Drive the technical direction and hands-on execution for cyber safeguard infrastructure.
• Establish production-quality reliability, observability, on-call, and SLA/SLO practices.
• Partner with teams across the company - security, research, policy and product - to translate evolving needs into durable platforms.
• Lead cross-functional technical work, create alignment, and unblock collaborators.
• Build reliable systems that support cyber evaluations and research workflows.
• Improve the scalability, usability, and operational safety of cyber safeguards.
• Mentor teammates and raise the engineering bar while remaining deeply hands-on.

You might thrive in this role if you have:

• Extensive experience owning large-scale production systems, including reliability, on-call, incident response, SLAs/SLOs, and operational excellence.
• Senior/staff-level technical leadership with a track record of driving ambiguous, cross-functional work, especially in cybersecurity.
• Strong hands-on software engineering and systems-design skills; you can go deep in the code and architecture, including systems where you are unfamiliar and quickly gain context to make meaningful changes while following existing patterns.
• Ability to collaborate closely with researchers and independently turn evolving research needs into robust infrastructure.
• Experience thinking and communicating about cyber capability, misuse risk, access patterns, safeguards, and deployment tradeoffs in high-stakes environments.
• Experience at a security company, supporting cyber evaluations, or building security/reliability infrastructure is a plus.
• Experience moving from strong engineering into research support is a plus; former engineering managers are welcome if they remain deeply technical and hands-on.
