About the Role

At Primary Venture Partners , a Most Loved Workplace® certified employer in the Financial Services space, Partnering with founders to build transformative companies at moments of maximum risk..

You are a residency-trained physician who also knows your way around electronic health record data and can code. Your primary responsibility is to create AI-ready datasets for our clients in our AWS environment. This will involve working across the organization with both engineers and clinical scientists to build our own clean, reproducible datasets and code base. Your team’s ultimate goal is to deliver the highest-quality data products possible to our clients, who are AI developers building products that improve patient health. You bring your clinical and data skill sets together in the following ways: Interacting with clients—ranging from AI startups to established life sciences companies—to understand their clinical data needs, and translate semantic concepts (e.g., “fatty liver disease”) into queries that can be executed in our data (e.g., ICD code ranges, regular expression matching for radiology reports). Querying complex source systems in a range of health data sources (e.g., EMRs, ECG data, DICOM data) to create high-quality datasets that can be used to train and validate AI algorithms. You have extremely high levels of attention to detail, but also know how to keep the big picture in mind. Working with non-medically-trained data scientists as they help create and validate these datasets. You are not afraid to dig into massive, confusing, disorganized new datasets and get them under control. You are excited to learn new environments, languages, and skills. This is a small, early stage company with enormous ambitions and everyone pitches in to do everything. Your specific responsibility is to supervise the process from customer request to dataset delivery. This will include the following: Perform complex data extraction, manipulation, and summarization of large amounts of data to create analytical datasets and provide a range of solutions to support customers’ AI activities. Support the design, testing, validation, analysis, and merging of multimodal data structures from a variety of source systems. Support all phases of SQL/analytical programming, data management, quality control, and reporting. Collaborate with customers to define and deliver on data requests with accountability for timely and high-quality delivery. Develop code to deliver high-quality data products on time to customers. Create summarized findings and recommendations that are clearly presented and adapted for audiences that have a varying range of technical and clinical experience. Ensure accuracy, data integrity, and validity of data and analysis in all work. Summarize the complexity of these data structures and operations into clear explanations and documentation for internal and external audiences. Present to senior leadership as well external audiences.

Frequently Asked Questions About Working at Primary Venture Partners

Common questions candidates ask about this role and Primary Venture Partners 's workplace

Primary is the premier early stage venture firm working alongside founders to build unicorns like Alloy, Chief, Electric, K Health, Slice, Vestwell, and many more. The firm takes a low-volume, high-conviction approach—and devotes unreasonable resources toward making sure founders can succeed. With an Impact team that outnumbers investors 2:1, operational experts spend 100% of their time making hires, signing customers, and enabling future fundraising to supercharge growth. This partnership with top-tier founders makes companies in Primary’s portfolio 2x more likely to raise a Series A and 19x more likely to reach a billion-dollar-plus valuation—a third of Fund I companies are unicorns, less than a decade out. We’re always excited to meet 99th-percentile founders building in B2B SaaS, built world, fintech, healthcare, infrastructure, and supply chain. And while we have a home court advantage in NYC, we invest globally, at pre-seed through A.
