• Build product features for authentication, encryption, and storage across ChatGPT and future consumer devices
• Build and maintain infrastructure for hardware security modules (HSMs)
• Integrate with private inference and computing infrastructure
• Operate systems at scale with high reliability, including an on‑call rotation
• Collaborate with a diverse set of cross‑functional teams across product, engineering, security, safety, policy, and legal

• Care deeply about user privacy and security
• Have 5+ years of experience in professional software engineering
• Have experience designing end‑to‑end encryption protocols (e.g., Labyrinth)
• Have experience building intuitive authentication experiences for users
• Have experience building and scaling HSM infra under strict security requirements (e.g., Juicebox)
• Take pride in building and operating scalable, reliable, secure systems
• Can collaborate well and drive alignment in the face of difficult trade‑offs
• Are comfortable with ambiguity and rapid change
