Senior Data Scientist

Probably Genetic is changing the lives of patients living with severe complex diseases. Our data platform is used by drug developers and patient advocacy groups to develop and launch treatments for these patients. Our technology discovers undiagnosed patients online analyzes their disease state using machine learning and at-home testing and enables compliant communication with doing so we help patients access diagnoses clinical trials and treatments as early as possible.

We are a tight-knit group of hard-working ambitious problem solvers united by a mission greater than ourselves. We do well by doing right by patients. We are developing some of the most cutting-edge solutions in healthcare and our roadmap is packed with innovations in bioinformatics AI and drug development. We have built a lean all-star team to help us bring our vision to life and we want you to be a part of it.

Probably Genetic has raised multiple rounds of funding from Silicon Valleys best investors including Threshold Khosla and Y Combinator and offer competitive salaries comprehensive benefits and meaningful early stage equity.

We are looking for a Senior Data Scientist who will own some of the most consequential diagnostic AI in rare disease: building validating and operationalizing the models that help us find and diagnose patients who have never had a name for their disease powering the analytical rigor behind our testing programs and shaping how we use data to make smarter product decisions.

• Own the end-to-end development validation and operationalization of PGs predictive diagnostic AI models from feature engineering through production deployment that power program eligibility decisions and clinical decisions for patients

• Run prospective testing experiments: apply diagnostic models to undiagnosed patients coordinate testing and track outcomes to continuously improve model performance

• Build and maintain PGs synthetic patient data pipeline a critical deliverable for our research programs and key input to our own model development lifecycle

• Optimize our patient intake experience using NLP and multimodal data analysis to determine which questions to ask in what order to maximize data quality and conversion

• Own API usage and cost optimization across PGs AI stack including prompt engineering model evaluation and ongoing performance monitoring

• Conduct ad hoc strategic analyses that inform product prioritization causality assessment and generate customer-facing program insights

• Establish MLOps infrastructure: model monitoring drift detection API observability and lightweight but durable operational processes

• Have the freedom to conduct blue sky research initiatives aimed at creating value from our data

• Work with Data Engineering to build a robust scalable data foundation that supports all of the above

We are looking for a few specific things that will help you succeed in this role:

• 7 years of experience in data science machine learning engineering or a closely related field

• Strong Python proficiency and fluency across the core data science stack: pandas NumPy scikit-learn PySpark and SQL

• Demonstrated end-to-end ML experience: you have taken models from problem definition through feature engineering validation deployment and monitoring in a production environment

• Experience with NLP techniques and applying language models to real-world problems

• Comfort with prompt engineering and evaluating external AI API performance (e.g. OpenAI)

• A track record of operating with high ownership in lean fast-moving environments where you have had to build structure as much as execute within it

• Strong analytical communication skills you can translate complex model outputs and data findings into clear actionable narratives for technical and non-technical audiences alike

Some things that are not required but you will learn on the job:

• Experience with Databricks or similar lakehouse/ML platform environments

• Familiarity with synthetic data generation techniques

• Domain knowledge in healthcare rare disease genomics or clinical research

• Experience with MLOps tooling and building observability infrastructure from scratch

• Exposure to biopharma or insurance analytics use cases

As with all new hires at Probably Genetic you will also need to be:

• A good person. We work with some of the most marginalized populations on the planet and empathy is key

• Patient-focused and motivated to have a lasting positive impact on humanity
