About the role

This role designs and builds the core data platform from scratch: a lakehouse that ingests high-volume events, processes them into FHIR standards, and serves both external hospital clients and internal analytics. The person in this role will own the architecture, work directly with hospital IT teams to gather requirements, and ship production code handling millions of records.

• Build developer-facing public APIs for external clients

• Own the full stack from event ingestion through serving data to external clients and internal analytics

• Use AI coding tools daily to accelerate development

Requirements

• 7+ years of hands-on software engineering experience, currently operating as an individual contributor shipping production code

• Proven experience designing and building high-volume event-driven architectures or event bus patterns

• Production experience with PostgreSQL and MongoDB at scale (handling millions of records)

• Professional-level fluency in both Portuguese and English

• Experience with large-scale, heavy data systems in production

• Based in Latin America (or exceptional cases in Europe with willingness to work LATAM hours and travel occasionally)
