About Turing
Turing’s mission is to accelerate superintelligence to drive real economic progress. Headquartered in San Francisco, Turing works with frontier AI labs to generate high-quality datasets, reinforcement learning environments, and frontier research benchmarks that improve model capabilities in software engineering, enterprise knowledge work, and advanced STEM reasoning. In software engineering, Turing is the largest and longest-running data provider in the category. Turing also works with Fortune 500 enterprises across financial services, life sciences, healthcare, retail, automotive, and CPG to build and deploy end-to-end agentic AI systems inside mission-critical workflows. By operating on both sides, Turing closes the loop between frontier research and enterprise deployment, turning real-world deployment signals into better data, evaluations, and more capable models.

Senior ML & Data Engineer — Data Quality & Sensitive Data Compliance
This is a full-time remote role based in Brazil or Colombia.
About the role
Enterprise data flows through our connectors, gets processed, and passes through a sanitization layer before anything downstream touches it. Two things have to be true at every step: the data is what we think it is, and no sensitive information — PII, PHI, company identifiable information (CII), or financial data — gets through. You'll own both. You'll do this primarily by building the machine learning that detects sensitive entities in text and image data and replaces them consistently at scale.
This is a hands-on IC engineering role with a QA mindset. You'll build the detection models, validation infrastructure, adversarial test sets, and audit processes that let us make strong claims about data quality and de-identification performance — and back them up with evidence. You'll work closely with a senior ML lead, with no client-facing responsibilities.
What you'll do
Data Quality
- Run deep dives into enterprise data to assess quality: topic coherence across connectors, domain depth within connectors, completeness, and consistency
- Design and automate validation suites for data pipelines — schema checks, completeness, drift detection, and reconciliation across raw → processed → sanitized stages
- Surface and characterize quality issues in ways that engineering and product can act on
Sensitive data compliance (PII / PHI / CII / financial)
- Design, train, and evaluate ML models (NER and other approaches) that detect sensitive entities across text and image-based documents such as scans, invoices, and presentations
- Build replacement pipelines that substitute detected entities with coherent alternatives, so the same entity always maps to the same replacement across every file in a corpus and the data stays useful
- Run these algorithms over large volumes of data to prepare it for downstream agentic task building
- Build adversarial test sets for de-identification across all sensitive data classes: edge cases, obfuscated identifiers, multilingual entities, OCR noise, and formats designed to slip past detectors
- Cover company identifiable information specifically — organization names and aliases, domains and email patterns, internal project and system names, org charts, vendor and partner relationships, contract terms, and any combination of details that could re-identify the source enterprise
- Cover financial data — account and routing numbers, card numbers, revenue and pricing figures, transaction records, tax IDs, and financial statements
- Measure and report de-identification performance by data class — entity-level precision and recall, leak rates, false-negative audits, and replacement consistency
- Implement regression gates in CI/CD so no pipeline change ships without passing data quality and sensitive-data checks
- Run sampling-based human-in-the-loop audits and maintain the audit trail as compliance evidence
- Partner with engineering on root-cause analysis when inconsistencies or leaks are found, and drive fixes to closure
What we're looking for
- About 4 to 5 years of hands-on machine learning experience, with ML as your primary background
- Strong Python for ML development and data validation (pytest, Great Expectations, Pandera, or similar)
- Solid SQL and experience validating data across pipeline stages
- Familiarity with sensitive data categories and the relevant standards — HIPAA Safe Harbor for PHI, GDPR/LGPD for PII, PCI DSS for cardholder data, and confidentiality/NDA obligations for company information
- Experience building and testing NER or other ML-based detection systems: building labeled eval sets, computing precision/recall, handling non-determinism
- Understanding of re-identification risk — how seemingly innocuous details combine to reveal an organization or individual
- Comfort with ambiguity and a fast-moving environment
- A skeptical, detail-oriented approach — you assume things are broken until you've proven otherwise
Nice to have
- Computer vision and OCR experience, especially building, scaling, and evaluating document pipelines for contracts, statements, invoices, presentations, and internal documents
- Hands-on experience with financial or healthcare data, including the privacy requirements specific to those industries
- Startup experience
- Auditing LLM or VLM outputs
- Synthetic sensitive-data generation (PII, PHI, company and financial records)
- Familiarity with the GCP data stack (BigQuery, GCS, Cloud Run jobs) and CI/CD integration
- Experience handling multi-tenant enterprise data with strict customer confidentiality requirements
- Compliance reporting or working with auditors
Why this role matters
Our enterprise customers trust us with their data on the condition that it can never be traced back to them. Every downstream model, dashboard, and customer commitment depends on the data being clean and the sanitization layer being airtight. When you find a leak, you've prevented an incident. When you prove there isn't one, you've earned the trust that lets the rest of the company move fast.
