## Description

We're looking for a senior software engineer to own the design and delivery of our API integration platform. This is the layer that connects Handtevy to other medical systems, including ePCR, EHR, narcotic and blood tracking systems, and more. You'll be the technical lead on how third-party systems authenticate, consume, and rely on our APIs, with real ownership in architecture decisions as well as implementation. This is critical work with real impact!

What You'll Do

 * Design and build bi-directional integrations between Handtevy and third-party platforms.
 * Design RESTful APIs with clear versioning, pagination, and idempotency guarantees, documented via OpenAPI/Swagger
 * Implement and harden authentication and authorization flows, including API key management, for third-party access
 * Build resilient, observable webhook and event-driven integration patterns
 * Own reliability, testing, and documentation standards for the integration layer, including security controls
 * Partner directly with integration vendors and internal product/frontend teams (product management, customer success, clinical, and implementation) to scope and ship new integrations
 * Evolve our public-facing API into a partner platform
