Research Engineer, Privacy

Skills

About the Role

You will work on the frontlines of safeguarding user data while keeping AI systems useful and efficient. You will design and prototype privacy-preserving ML algorithms, measure and strengthen model robustness against privacy attacks, build libraries and evaluation suites, investigate privacy-performance trade-offs, define privacy standards and threat models, and collaborate across Security, Policy, Product, and Legal.

Requirements

• Hands-on research or production experience with privacy-enhancing technologies
• Fluency in modern deep-learning stacks (PyTorch/JAX)
• Track record of publishing or implementing novel privacy or security work
• Ability to explain complex attack vectors to non-experts
• Clear communication and rigorous documentation

Responsibilities

• Design and prototype privacy-preserving machine-learning algorithms (differential privacy, secure aggregation, federated learning) at scale
• Measure and strengthen model robustness against membership inference, model inversion, and data memorization leaks
• Develop internal libraries, evaluation suites, and documentation for privacy techniques
• Lead investigations into privacy-performance trade-offs of large models and publish insights
• Define and codify privacy standards, threat models, and audit procedures across the ML lifecycle
• Collaborate across Security, Policy, Product, and Legal to translate regulatory requirements into technical safeguards
