Senior Data Scientist – LLM / Clinical NLP

Senior Data Scientist – LLM / Clinical NLP

Full-time B2B | Remote Poland | US Healthcare Real-World Data Context

We are an AI-native data and technology partner for private capital and healthcare. Founded in 2010 and headquartered in Warsaw, we work with leading PE firms, VC funds, and healthcare organizations to build proprietary data infrastructure, deploy AI solutions, and drive AI-native transformation.

Our clients manage a cumulative $1.2T+ in assets. Our average engagement runs five years. Our NPS sits above 80. We don't need to claim credibility – we can show it.

We've also done to ourselves what we now do for clients. We've restructured our own company around AI – tools, policies, roles, delivery models. This isn't a pitch. It's a playbook we've already run, and we're hiring the engineers who will run it for others.

The Opportunity

Our client is a US healthcare data company. They turn real-world EHR data from specialty registries (ophthalmology, urology, oncology) into research-grade data products used for real-world evidence.

They are bringing a clinical-data extraction product to market and need extra senior capacity in their Data & Science team. The core problem: getting reliable, structured facts out of messy clinical notes with language models, and proving they are reliable. Your outputs feed research studies and commercial data products, so accuracy and explainability matter as much as shipping.

You'll join the client's Data & Science team (the role is called Senior Quantitative Scientist on their side) and work every day with their Product and Medical teams on the US East Coast.

What you'll be doing

The core of the work is applying language models to unstructured clinical text: building extraction pipelines, measuring how well they work, and taking them to production. You'll work with Medical and Product to turn clinical questions into concrete model requirements, and explain results to people who don't read confusion matrices. We're looking for someone who combines research depth with production instinct.

Benefits

• Unrestricted AI Stack & Premium Gear: Fully paid licenses for Cursor, Claude Pro, etc.
• Total Autonomy (Remote-First): No filler meetings, no Jira bloat, no micromanagement. You own the workflow. We care about shipped systems in production, not logged hours.
• Direct Impact: You'll work face-to-face with our CEO, CTO & VPs and directly with client leadership.
• Frontier Engineering Culture: Build alongside elite engineers who are shipping systems that drive real business decisions. Backed by continuous growth and a strong knowledge-sharing culture (check our YouTube).
