Algorithms Engineer designing and implementing core components of differential privacy systems for Oblivious. Focused on translating mathematical theory into production-ready code and robust algorithms.
Responsibilities
Design, implement and evaluate privacy-preserving algorithms.
Implement and integrate various differential privacy mechanisms.
Calibrate and apply noise mechanisms (Gaussian, Laplace) based on rigorous sensitivity analysis.
Use Python AST manipulation and static analysis to enforce a DP-safe execution environment, ensuring user-submitted code cannot leak private information.
Privacy Accounting & Mechanisms: Analyse and implement privacy accounting and mechanisms.
DP Synthetic Data: Implement and benchmark state-of-the-art algorithms for high-dimensional synthetic data generation.
Collaborate with cross-functional teams to design, develop, and deploy privacy-preserving systems.
Requirements
Strong foundation in probability, statistics, and linear algebra. You must be comfortable with statistical modelling, proving bounds, and reasoning about error/variance.
Proficiency in Python for scientific computing, including numerical stability considerations (e.g., floating-point precision, clipping, scaling).
Demonstrated ability to translate mathematical concepts from academic papers or technical specifications into robust, well-tested code.
Excellent knowledge of compiler engineering, ideally having built a simple compiler in the past.
Experience with data structures and ASTs.
