Data Scientist

About the role

Healthcare is in crisis and the people behind the results deserve better. With more and more data coming from wearables, lab tests, and patient–doctor interactions, we’re entering an era where data is abundant.

Junction is building the infrastructure layer for diagnostic healthcare, making patient data accessible, actionable, and automated across labs and devices. Our mission is simple but ambitious: build the infrastructure that makes predictive, personalized care possible.

If you're passionate about how technology can supercharge healthcare, you’ll fit right in.

Backed by Creandum, Point Nine, 20VC, YC, and leading angels, we’re working to solve one of the biggest challenges of our time: making healthcare personalized, proactive, and affordable. We’re already connecting millions and scaling fast.

Short on time? TL;DR

- You: Can define what should be measured, how it should be modeled, and how those insights should shape product and company decisions.

- Ownership: You’ll own Junction’s highest-leverage statistical, modeling, and evaluation work across diagnostics, clinical workflows, and AI-enabled product development.

- Scope: This is not a pure IC modeling role and not a reporting role. You’ll set the methodology, research roadmap, and decision framework for how Junction uses data to drive product, clinical, and business outcomes.

- Salary: $180,000 – $200,000 + equity

- Location: Fully remote (EST timezone only)

Why we need you

Junction sits in the flow of high-value diagnostics and clinical data. As the company grows, our advantage moves beyond just having data to having the ability to turn it into reliable intelligence improving product decisions, customer outcomes, and the performance of the business.

Some of that work exists today, but it is not yet owned as a coherent function. Models get built. Analyses get done. Experiments answer local questions. But we need someone who can define the broader scientific and analytical system: what we should measure, what methods we trust, where modeling creates real leverage, and how that work translates into products and decisions that hold up outside a demo.

We’re hiring our first Data Scientist to take ownership of, and establish that standard.

This role will lead Junction’s most important modeling, experimentation, and evaluation work. You’ll partner closely with data, product engineering and leadership teams to drive the analytical roadmap by which Junction can leverage differentiated value from data.

What you’ll be doing day to day

- Own the research and modeling work underlying Junction’s highest-priority data science opportunities across diagnostics, clinical workflows, and AI-enabled product features

- Define rigorous frameworks for measurement, experimentation, and causal evaluation so we can distinguish signal from noise and make decisions we can defend

- Lead development of predictive models, segmentation approaches, risk or routing logic, and other statistical systems that directly inform product and business strategy
