Job 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

Requirements

5+ years of backend software engineering experience, including meaningful work on API platforms or system integrations
Strong hands-on expertise with Node.js and NestJS (or comparable backend frameworks) and TypeScript
Deep working knowledge of OAuth 2.0, JWT, SSO/SAML, and API security best practices
Production experience with relational databases (MySQL/Aurora preferred) and NoSQL stores (MongoDB, DocumentDB, etc.)
Comfort with Docker, CI/CD pipelines (GitHub Actions or similar), and AWS services (Lambda, API Gateway, SQS/SNS/EventBridge, CloudWatch)
Real AI-augmented engineering practices
Bachelor’s degree in Computer Science or a related field, or equivalent hands-on experience

Nice to Have

Healthcare interoperability experience (HL7, FHIR, NEMSIS, etc.), and/or work with EHR/ePCR platforms
Healthcare, EMS, or other regulated-industry background
Familiarity with PHP and Laravel
Event-driven architecture experience: Kafka, Kinesis, EventBridge, or similar
Observability platforms: Datadog, New Relic, or similar

Benefits & conditions

Competitive salary commensurate with experience.
Comprehensive health, dental, and vision coverage.
401(k) with company match
Paid time off and paid holidays
