About Previu

Previu is a preventive health company. Every family gets one connected health record and one named care navigator, who guides them from lab results to the next step. We are preparing for our India rollout.

The role

You will be our first data scientist. Your job is to make sure the data, models and AI assistant we put in front of families are tested, explainable and safe.

Your first six months run in two phases:

• Synthetic data: build the evaluation framework, the data pipelines and an AI assistant test set, together with our doctors.
• Scrubbed real data: audit it, recalibrate, reduce hallucinations and unsafe answers, and monitor for drift and failures.

You start by learning what exists today, then we agree together what to build first.

What you bring

• 5+ years in data science or ML, with at least two models taken to production
• Strong Python, SQL and statistics, and honest model evaluation
• Hands-on LLM evaluation: hallucination testing, RAG or guardrails
• Experience with messy lab or longitudinal data, and with sensitive data under privacy-by-design
• Judgement to choose a simple model when it works, and to explain limits to doctors and founders
• Comfort working on your own at an early-stage company

Nice to have (any one): healthcare or regulated-domain work, clinical NLP, wearable data, Indian lab data.

How to apply

Apply with your CV and attach a note under 200 words as your cover letter (or email it to rakesh@previu.health), covering:

1. A model or LLM system you took to production, your part and the result
2. How you measured and reduced wrong or unsafe outputs
3. How you monitored it after deployment and handled a failure

Please include your notice period and expected compensation.
