Co-founder / Chief Technology Officer at Early-stage health data infrastructure startup
Women's health has a massive data problem—clinical information is trapped in fragmented silos, preventing researchers and clinicians from seeing the full picture. This well-funded healthtech startup is building the interoperability layer to change that. We are looking for a technical co-founder or founding CTO to architect the platform from the ground up, moving from 0 to 1 in a space with huge market potential. If you have experience with FHIR, HL7, or building elite data pipelines at companies like Palantir or Flatiron Health, this is your chance to define the technical foundations of a company transforming reproductive medicine.
