This is one of the hardest and most important problems in the business, and you'll be central to solving it. Key Responsibilities Drive the architecture, design, and build of complex pipelines for AI agents and data ingestion Develop and scale data integration infrastructure that connects seamlessly to a wide range of external systems Solve tough interoperability challenges that directly unlock customer value Work shoulder-to-shoulder with engineering and product to improve onboarding speed and shape the data strategy Contribute to the team's architectural vision and long-term technical roadmap Drive code quality through reviews and technical design docs, and spread knowledge across the team Nice to Have Staff-level experience Background at a high-bar startup or a top-tier, fast-moving tech company Domain experience in healthcare, regulated environments, or complex data interoperability Experience working closely with customers to shape what gets built This is a rare shot to join early, shape the technical direction, and build something that genuinely matters -fast.
