## Job description

Senior/Staff Machine Learning Data Scientist

In Brief

- We’re an early-stage startup on a mission to make healthcare proactive by empowering physicians, nurses, and care team members with real-time data to save lives.
- TLDR: Independent end-to-end model development with ability to work cross-functionally with Clinical, Engineering, and Product to clarify and prioritize specifications and features for our life-saving AI models.

## Who We Are

Bayesian Health’s mission is to improve patient outcomes by empowering clinicians with the insights they need to make the right decision for the right patient at the point-of-care. We’re a diverse team of clinicians, engineers, machine learning experts, product designers, and performance improvement leaders committed to enabling smarter, patient-specific care delivery through unlocking the power of data. We’re funded by top tier tech and biotech investors: Andreessen Horowitz, American Medical Association’s venture arm, Catalio Partners, and LifeForce Capital. Our company has won many awards; most recent recognitions include: Forbes AI Top 50, World Economic Forum Tech Pioneer, Time Best Inventions, BioTech AI Company of the Year.

## What you’ll do

As a Senior/Staff Machine Learning Data Scientist, you are not satisfied with training and tuning ML models that predict clinical conditions in patients; you also want to own the effectiveness of your model in the real world. In practice, that means you aren’t afraid to get your hands dirty by writing data mapping code, debugging a specific patient case by following patient data as it moves through our AWS services, or improving the timeliness of your model’s predictions by reading and writing production-grade Python and SQL code.

## Responsibilities

- Model Prototyping: Develop and tune innovative, new ML models and labeler systems based on deep understanding of clinical use cases and state-of-the-art ML methods
- Productionizing: The same models that you develop with production-grade Python
- Deploying: Identify strategies for improving our production ML-based systems, and write, debug, and deploy production-grade Python code to implement those strategies
- Cross-Functional Alignment: Data Science for storytelling – understand model performance and metrics, and present this to technical and non-technical users, both internally and externally

## Minimum qualifications

- Ph.D. in a relevant field plus 3+ years experience shipping ML based software products
- Experience owning your ML models from prototyping to production, especially real-time algorithms that update dynamically across time
- Experience writing production-grade Python and SQL code to implement and evaluate ML models in production systems
- Track record of using statistics and performance metrics to compare end-to-end ML and product performance

## Preferred qualifications

- Experience shipping breakthrough or 0-1 products from end to end, interpreting and leveraging State-of-the-Art methods to do so
- Experience using messy clinical and health data to design new products for large Health Systems
- Experience with any of the following: PyTorch, PySpark, HL7, FHIR, EHR, time series data, signal processing, MLFlow, anomaly detection, Bayesian statistics, quantile regression, time-series forecasting
- You bring passion and enthusiasm to your work, and are excited to join a growing team to Get Stuff Done and save lives!

## About Bayesian Health, Inc.

## Company Overview
- **One-liner**: Bayesian Health provides a real-time clinical intelligence platform that uses AI to help health systems deliver proactive, high-reliability care by continuously monitoring patients and surfacing actionable insights.
- **Entity Type**: Private (Venture-backed)
- **Headquarters**: New York, United States
- **Founded**: Year not publicly specified; founded by Dr. Suchi Saria
- **Founders**: Dr. Suchi Saria (machine learning expert and health AI pioneer)

## Core Business
- **Primary industry**: Healthcare AI / Clinical Decision Support
- **Target customers**: B2B; large health systems and hospitals
- **Mission or purpose**: To raise the standard of patient care by enabling proactive, high-reliability care through real-time clinical intelligence, turning data noise into trusted, decisive action.

## Products & Services
- **Real-Time Clinical Intelligence Platform**: An AI-powered SaaS platform that continuously monitors every patient by reading the full electronic health record (EHR). It establishes each patient's baseline, detects meaningful changes, and surfaces only the patients who need attention with clear next steps. The platform targets top drivers of mortality and hospital utilization, including sepsis, deterioration, palliative care, transitions of care, heart failure, hospital-acquired pressure injuries (HAPI), and malnutrition. It is designed to integrate directly into the EHR workflow.

## Market Standing
- **Valuation/Market Cap**: Not publicly available
- **Key Metric**: Total Funding of **$15.2M** (as of July 2021)
- **Notable Investors/Partners**: Led by **Andreessen Horowitz** (a16z) in a $15M venture round (2021); also received a $225K grant from the **National Science Foundation** (2017). Partners with leading health systems.
- **Growth Signals**: Headcount grew **+34.3% YoY** to 38 employees. Received **FDA clearance** for the first continuous AI monitor for sepsis. Published a 5-site study in *Nature Medicine* showing an **89% reduction in mortality** and a **0.5-day reduction in length of stay**. Has 12 active job postings.

## Competitive Advantages
- **Clinician-Trusted Accuracy**: The platform flags patients **3+ hours earlier** than standard EHR alerts with **20x lower flag volume**, solving the "alert fatigue" problem that plagues other clinical AI tools. This drives adoption rates far above industry norms (e.g., one customer reported <1% adoption with other tools vs. high adoption with Bayesian).
- **Peer-Reviewed Validation**: Built on decades of research from Dr. Suchi Saria and published in top journals like *Nature Medicine*, with proven real-world outcomes (e.g., 89% reduction in mortality, 0.5-day reduction in length of stay across a 5-site study).
- **FDA Clearance**: Received FDA clearance for the first continuous AI monitor for sepsis, a significant regulatory moat.
- **Proven ROI**: Delivers measurable improvements in mortality, length of stay, and readmissions, making it a durable strategy for health systems rather than a disconnected initiative.

## Strategic Focus
- **Product Expansion**: Targeting top drivers of mortality and hospital utilization, including sepsis, deterioration, palliative care, heart failure, HAPI, and malnutrition.
- **Commercial Growth**: Scaling partnerships with leading health systems and expanding commercial reach.
- **Talent Acquisition**: Actively hiring across engineering, product, data science, and clinical roles to support growth.

## Why Work Here
- **Mission-Driven Impact**: Employees are directly involved in saving lives and improving patient outcomes at scale, with a clear focus on reducing mortality and hospital harm.
- **Culture**: Values include "Patients at the center," "Whole people, shared respect," "Truth seekers, stronger together," "No surprises, clear signals," and "Hard problems, real breakthroughs." The company emphasizes open debate, clear communication, and a high bar for excellence.
- **Work Environment**: Based in New York, NY, with a presence in Australia. The team is 79% US-based. The culture is described as collaborative, with a focus on solving hard problems.
- **Engineering & Science Focus**: The technical team makes up 26% of the workforce. The company is actively hiring for roles like Staff Machine Learning Engineer, Forward Deployed Software Engineer, and Director of AI/ML, indicating a strong emphasis on engineering and data science.
- **Notable Perks/Culture**: The company emphasizes "whole people, shared respect," making space for growth inside and outside of work. The mission is directly tied to saving lives and improving patient care.
