About this role
About the Role
Build privacy and anonymization systems that help make sensitive real-world data safe and useful for AI training. You will develop end-to-end methods to protect sensitive information while preserving the structure and signal needed for downstream training, evaluation, and synthetic data workflows.
What You'll Do
-
Build systems to detect PII, quasi-identifiers, credentials, and other sensitive information, and tailor transformations to data types and use cases.
-
Develop and benchmark detection approaches that combine rules, statistical models, classifiers, and LLM-based methods.
-
Create production pipelines that anonymize data before it enters processing, training, evaluation, or synthetic data workflows.
-
Develop evaluation frameworks for privacy risk and retained utility, including recall-weighted metrics, leakage tests, and adversarial re-identification attempts.
-
Design robust systems that handle new sources, schema drift, unusual formats, and sensitive information in unexpected fields.
-
Partner with engineering, research, operations, and customers to turn privacy requirements into practical safeguards.
What We're Looking For
-
At least 2 years of experience building production data or ML systems in Python, with strong proficiency in the language.
-
Hands-on experience with PII detection, removal, or anonymization, including transformations that preserve useful data characteristics while hiding underlying information.
-
Experience with information extraction, named-entity recognition, classification, or related methods for finding rare or sensitive content.
-
Ability to build end-to-end data pipelines and compare approaches across recall, precision, latency, cost, and downstream utility.
-
Understanding of redaction, masking, pseudonymization, anonymization, and synthetic data generation.
-
Experience handling schema drift and edge cases; work with sensitive data or privacy-enhancing techniques such as differential privacy, k-anonymity, secure aggregation, or format-preserving encryption is valuable.
-
Experience with low-latency or high-throughput ML inference and data processing is beneficial.
