Research Engineer, Privacy

About the Role

As a part of the Privacy Engineering Team, you will work on the frontlines of safeguarding user data while ensuring the usability and efficiency of our AI systems. You will help us understand and implement the latest research in privacy-enhancing technologies such as differential privacy, federated learning, and data memorization. Moreover, you will focus on investigating the interaction between privacy and machine learning, developing innovative techniques to improve data anonymization, and preventing model inversion and membership inference attacks.

This position is located in San Francisco. Relocation assistance is available.

In this role, you will

• Design and prototype privacy-preserving machine-learning algorithms (e.g., differential privacy, secure aggregation, federated learning) that can be deployed at OpenAI scale.
• Measure and strengthen model robustness against privacy attacks such as membership inference, model inversion, and data memorization leaks-balancing utility with provable guarantees.
• Develop internal libraries, evaluation suites, and documentation that make cutting-edge privacy techniques accessible to engineering and research teams.
• Lead deep-dive investigations into the privacy-performance trade-offs of large models, publishing insights that inform model-training and product-safety decisions.
• Define and codify privacy standards, threat models, and audit procedures that guide the entire ML lifecycle-from dataset curation to post-deployment monitoring.
• Collaborate across Security, Policy, Product, and Legal to translate evolving regulatory requirements into practical technical safeguards and tooling.

You might thrive in this role if you

• Have hands-on research or production experience with PETs.
• Are fluent in modern deep-learning stacks (PyTorch/JAX) and comfortable turning cutting-edge papers into reliable, well-tested code.
• Enjoy stress-testing models-probing them for private data leakage-and can explain complex attack vectors to non-experts with clarity.
• Have a track record of publishing (or implementing) novel privacy or security work and relish bridging the gap between academia and real-world systems.
• Thrive in fast-moving, cross-disciplinary environments where you alternate between open-ended research and shipping production features under tight deadlines.
• Communicate crisply, document rigorously, and care deeply about building AI systems that respect user privacy while pushing the frontiers of capability.
