Backend Engineer (Kotlin) – Healthcare System Integrations

We build a mobile documentation app for senior care and are looking for a backend engineer to work on our integrations with third-party care management / EHR systems.

What you'll do

- Build and maintain integrations that sync data between our platform and external healthcare systems (mostly REST and GraphQL APIs, occasionally XML).
- Map external data models onto our internal domain model and handle the edge cases real-world data throws at you.
- Write tests, take part in code review, and keep integrations robust and observable in production.
- Work through vendor API docs and sandbox environments, and raise questions with vendors when the docs don't match reality.

What we're looking for

- Strong Kotlin (JVM) and coroutines experience.



Ktor is a plus.
- Hands-on experience integrating third-party APIs: OAuth2, pagination, rate limits, retries, idempotency.
- Comfortable with Gradle, Git, Docker and CI pipelines.
- Careful with data: you test edge cases and think about failure modes before they reach production.
- Transparent written English and comfortable working asynchronously.

Nice to have

- Experience with US healthcare / EHR systems, or with healthcare data standards (HL7, FHIR).
- Familiarity with GraphQL.
- Experience handling sensitive personal or health data (HIPAA / GDPR).
