📋 Description

• Build systems to detect PII, quasi-identifiers, credentials, and other sensitive information and design transformations based on data type and downstream use case • Develop and benchmark detection approaches combining rules, statistical models, classifiers, and LLM-based methods • Build production pipelines that anonymize raw data before downstream processing, training, evaluation, or synthetic data generation • Create evaluation frameworks measuring privacy risk and retained data utility, including recall-weighted metrics, leakage tests, and adversarial re-identification attempts • Design systems robust to new data sources, schema drift, unusual formats, and sensitive information embedded in unexpected fields • Work with engineering, research, operations, and customers to translate privacy requirements into practical technical policies and safeguards • Own the full pipeline for protecting privacy without destroying the structure and signal valuable for AI-agent training • Participate in a 2–3 day work trial during the application process

🎯 Requirements

• Strong proficiency in Python and experience building reliable production data or ML systems • Experience with information extraction, named-entity recognition, classification, or related methods for detecting rare or sensitive content • Strong experimental instincts and ability to compare approaches across recall, precision, latency, cost, and downstream data utility • Understanding of redaction, masking, pseudonymization, anonymization, and synthetic data, and when each is appropriate • High attention to detail and ability to reason about subtle leakage paths, edge cases, and adversarial failure modes • Experience building data processing pipelines end-to-end without a fully prescribed roadmap • Hands-on experience with privacy-enhancing technologies such as differential privacy, k-anonymity, secure aggregation, or format-preserving encryption (strong candidates may also have) • Experience with sensitive data in healthcare, finance, or security (strong candidates may also have) • Experience building low-latency or high-throughput ML inference and data-processing systems (strong candidates may also have) • Experience working in unstructured problem spaces and taking ownership from early research through production deployment (strong candidates may also have) • Early-stage startup experience and strong communication skills for collaboration across teams and time zones (strong candidates may also have) • Ability to work hours that 70–80% overlap with either San Francisco or Singapore time zones • Full-time availability

🏖️ Benefits

• 100% covered top-of-the-line medical, dental, and vision from Blue Shield of CA (US employees) • Lunch and dinner when you’re in the office (in-office employees) • Company-wide holiday break (Christmas Eve to New Year’s Day) on top of PTO and paid holidays • Unlimited access to tokens for ChatGPT, Claude Code, Cursor, etc. • Equinox membership (US employees) • 401k (US employees) • Commuter benefits (US employees) • Support for relocation and visas for strong full-time candidates to the US or Singapore
