Data Engineer II

About Knit Health Knit Health is building a novel clinical foundation model to improve how healthcare is delivered. We combine expertise in AI with deep clinical knowledge to develop safe, trustworthy systems that improve care, expand access, and reduce waste. Knit is led by a founding team with roots at the University of California, Berkeley. The team has developed a novel AI architecture designed to reason like physicians. We are now using that foundation model, together with frontier clinical LLMs, to build a next-generation clinical intelligence platform for healthcare providers. We are venture backed and work with U.S.-based health systems and data providers.

What you'll do As a Data Engineer II at Knit Health, you'll be a foundational member of a small, high-impact team building the data infrastructure behind our clinical AI platform. You'll help develop the clinical world data model that powers our AI systems, transforming complex healthcare data into reliable inputs for model training, research, and real-world applications.

• Design, build, and maintain data pipelines and infrastructure at scale, collaborating closely with our science, AI, and product teams.
• Expand our data integrations to new clinical and healthcare data sources, including the processing, modeling, and quality safeguards needed for reliable downstream use.
• Build and optimize large-scale, data processing systems for performance, scalability, and reliability.
• Drive data and product integrations with healthcare clients deploying our AI models.
• Help shape our data architecture and establish standards for data quality, testing, documentation, and observability.

Minimum qualifications We're looking for candidates with strong engineering fundamentals, experience building production data systems, and the ability to independently solve complex technical problems.

• Systems thinking and problem-solving: Ability to reason from first principles, understand how complex systems work, and independently design and troubleshoot solutions without relying exclusively on off-the-shelf tools.
• Data engineering fundamentals: Strong understanding of data modeling, ETL/ELT, orchestration, database architecture, and data quality, including the underlying principles that make data systems scalable and reliable.
• Large scale data processing: Hands-on experience processing large datasets using Spark or comparable frameworks, with an understanding of distributed computing, performance, and scalability.
• Engineering experience: Approximately 4-6 years of professional data engineering experience, or equivalent hands-on experience designing, building, and maintaining production data pipelines and infrastructure.
• Programming proficiency: Strong Python and SQL skills, including complex queries, data transformations, and writing clean, maintainable, well-tested code.
• Cloud infrastructure: Hands-on experience with a major cloud platform such as Azure, AWS, or GCP.

We value demonstrated engineering capability over a specific educational path. A background in computer science, engineering, mathematics, physics, or a related technical discipline is valuable, but we also welcome candidates who have developed equivalent expertise through hands-on experience. Nice-to-haves
