About the role

• 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.
• **Desirable**
• Experience in designing and implementing privacy-preserving algorithms
• Experience with machine learning, particularly with noise models, statistical learning theory, or generative models.
• Familiarity with SQL parsers or database internals.

Benefits

• Private health insurance and pension plan
• Paid time off
• Training & development
