The posting

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.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
