О компании
- Since 2023, our mission has been clear: to be the north star of patient equity.
- Every day, we strive to bridge the gaps in healthcare access and outcomes to ensure that every patient, regardless of background or circumstance, receives the care they deserve. As a member of our team, you'll be at the forefront of innovation, working alongside passionate individuals who share your dedication to creating best-in-class, patient-centric products in healthcare. Together, we're revolutionizing the way people understand their health and working with the world's top researchers to accelerate innovation.
Обязанности
- Most of what matters in a health record isn't in a structured field - it's in the note, the discharge summary, the pathology report, the scanned fax. Turning that unstructured clinical text into trustworthy, structured features is what makes a longitudinal health history usable for research, and it's one of the highest-leverage capabilities can own.
- You'll be our first ML hire, joining Platform Engineering and reporting to the Head of Platform Engineering, as technical owner of this multi-quarter effort. The interesting decisions are still open - what we extract first, how we know we're right, what a mature extraction pipeline looks like at our scale. There's no existing approach to inherit or defend.
- The work draws on two toolkits. Roughly 70% is applied ML on clinical text: entity extraction, classification, sequence labelling, annotation strategy, error analysis, calibration, and the evaluation discipline that tells you whether your numbers mean anything. Roughly 30% is LLM-based: prompt development, structured output, retrieval, and the evals and observability that keep generative approaches honest. Deciding which approach a given problem calls for is the most interesting part of the job, and that call is yours.
- We're looking for a leader in this seat: setting technical direction rather than waiting to be handed a problem. If this grows the way we think it will, leading the team we build around it is on the table.
- Own the full lifecycle of extraction models - framing, data/annotation strategy, model selection, training/fine-tuning, evaluation, deployment, monitoring, retraining. Not a research seat, not a hand-off seat.
- Define what "accurate enough" means with clinical and customer-facing stakeholders, and build the evaluation harness that makes the answer defensible - the first deliverable, not a follow-up.
- Partner with Clinical Data Managers on curation design and own the technical half of QA/QC alongside them: which variables are extractable, how an instruction becomes a model spec, and the tooling/sampling/error analysis behind human-in-the-loop review.
- Build clinical NLP pipelines against messy real-world data and work with backend engineers to productionize what you build.
- Use LLMs with the same rigor you'd apply anywhere: versioned prompts, real evals, tracked cost/latency, known failure modes.
- Make extraction quality legible to non-ML colleagues, and treat de-identification, PHI handling, audit trails, and access controls as part of the modelling problem, not someone else's checklist.
- Help shape the roadmap around the problems you see - a mission and a close working partner, not a backlog.
Требования
- Healthcare or life sciences experience with real clinical data - clinical notes, EHR data, claims, registries, or similar. This one is not negotiable for us.
- 6+ years in applied ML, with models you personally took from problem statement to production and kept working - you know what degraded, how you found out, and what you did.
- Depth in applied ML on text: information extraction, NER, classification, sequence labelling, weak supervision, and the evaluation practice around them, including annotation guidelines and inter-annotator agreement you've had to act on.
- Practical, current experience with LLM-based approaches: prompt development, structured output, retrieval, fine-tuning where warranted, evals and observability for generative systems - enough to know where they help, and where they quietly don't.
- Strong engineering fundamentals in Python. Your work runs in production, not only in a notebook.
- Strong collaboration instincts across the ML boundary: you define problems with stakeholders before solving them, write clearly, and bring people along.
- A track record of solving problems rather than closing tickets. Self-directed, comfortable without a playbook, and comfortable being wrong in public when the evidence says so.
Будет плюсом
- Fluency with clinical terminologies and standards: SNOMED CT, ICD-10, LOINC, RxNorm, CPT, FHIR
- Experience with HIPAA, SOC 2, de-identification methodology, or IRB and regulatory-grade data work
- Experience as an early or first ML hire
- Experience building or running human-in-the-loop annotation and QC operations at scale
- OCR and document-understanding experience on low-quality real-world documents
- Experience mentoring or leading ML engineers, or interest in growing that way

Другое
- is the first and only company that lets anyone in the U.S. gain access to nearly a decade of their health data in under 30 seconds — 100% free. All your health records, across every doctor, in one place, always up to date.
- We are the only patient-powered real-world data platform delivering comprehensive, patient-authorized longitudinal health insights to accelerate biopharma innovation. Unlike traditional RWD providers who deliver fragmented institutional data, we empower patients to access 20+ years of their health records, then transform these complete health journeys into fit-for-purpose datasets for evidence generation, regulatory submissions, and market access. We are growing 5x year over year, have raised close to $30M in funding, and are backed by tier-1 investors including Spark Capital, Khosla Ventures, and Bling Capital.
- Working with the world's top researchers, we turn health insights into life-changing action for millions of people around the world.
- Not a research role. The bar is extraction quality in production, not publications.
- Not an LLM-wrapper role. If your instinct is that every problem is a prompt away from being solved, we'll frustrate each other.
- Not a large-team role yet. You'd be the first ML engineer in a small Platform Engineering function - breadth and influence, and fewer specialists to lean on.
- Not a role where someone hands you a clean labelled dataset. Building it is the job.
- Ground-floor ownership of a capability with direct commercial weight, with influence over architecture, roadmap, and eventually hiring.
- Both halves of the modern ML toolkit in one seat, on a problem where the choice between them genuinely matters.
- A manager who treats process and people work as legitimate engineering work, and intends for this seat to grow.
- Health tech means the work has stakes - better extraction means higher quality research
