Clinical Data Scientist

About Us

Our mission is to make healthcare reimbursement transparent and fair (/phare), so providers can spend more time caring for patients and less time haggling over costs. We specifically focus on the most complex AI challenges that require novel R&D, with a team that blends AI researchers and engineers with clinicians, and payment experts. Backed by General Catalyst, we’re scaling quickly - join us!

The Role

You will join a tight-knit AI team as a hands-on data scientist and resident expert in clinical text, shipping ML systems into production and pushing forward state of the art. Expect to:

• Prototype end-to-end text pipelines - clean and normalise raw EHR notes, choose an architecture, train, and evaluate - at the pace of days not months.

• Train transformer models - fine-tune large language models for coding, summarisation, and clinical reasoning, then keep them fresh with continuous-learning loops.

• Implement LLM workflows - build retrieval-augmented generation (RAG) and lightweight multi-agent chains that output clear, reference-backed answers.

• Explore new datasets - run exploratory data analysis, map content to ICD-10, CPT and flag data gaps before modelling.

• Productionise your work - convert research prototypes into reliable services with CI/CD, monitoring, and rollback.

Who we're looking for

• 3+ years applying NLP or data-science to clinical (or similarly complex) text.

• Proven ability to take a project from EDA → model design → evaluation → production code in Python (SQL, Pandas, modern ML/NLP libraries).

• Hands-on experience training transformer models and building RAG or agent-based LLM pipelines.

• Familiar with EHR formats and healthcare ontologies (ICD-10, CPT, LOINC, SNOMED).

• Track record operating production-grade ML systems with monitoring and uptime targets.

Bonus points

• Peer-reviewed publications or open-source contributions in clinical NLP.

• Experience with reinforcement-learning methods such as GRPO (or similar policy-optimisation techniques) for model refinement.

• Experience in customer-facing roles communicating data science requirements and gathering specs from end users.

Benefits

• Top-of-market compensation (salary + equity)

• Flexible PTO & hybrid culture (SoHo HQ 3 days/wk; exceptional remote considered)

• Mission-driven, collaborative team

• Twice-yearly offsites to align, build, and celebrate.
