Qualifications

· 7+ years of professional software engineering experience, with principal-level impact in at least one prior role

· Designed and operated large-scale distributed systems in production

· Comfortable owning systems end-to-end, from design through production operations

Our stack: Python (FastAPI), React/TypeScript, MSSQL, Redis, Azure (Container Apps, Static Web Apps, DevOps Pipelines), Terraform.

Nice to have

· Health tech experience or familiarity with EHR systems (eClinicalWorks, Ellkay, Redox, FHIR)

· Experience scaling a multi-tenant SaaS platform

· Experience building clinical rules engines or decision support systems

· Public speaking or writing on technical topics

Location

Based in the Bronx, co-located with Essen Health Care. We sit next to the care coordinators, clinicians, and operators who use the platform every day and work in a community that we serve. Instead of scheduling a user research session, you can walk down the block and see someone using what you built.

Hybrid: 3 days on-site, 2 days remote.

Why this role

You'll shape the technical foundation of a platform that's live, growing, and directly improving healthcare for underserved communities.
