Platform Engineer, Data Services

Vytalize Health•Kansas City, KS

About The Position

As a Platform Engineer on Data Services, you will help design, build, and operate the clinical decision support and API-driven data delivery platform that enables Vytalize Health to embed timely, actionable clinical insights directly into provider workflows. Working cross-functionally with Data Engineering, Product, Clinical Operations, and EMR partners, your solutions will transform how clinicians access data—moving from external tools and workarounds to seamless, in-workflow decision support via CDS Hooks and real-time APIs. You will own the technical foundation for Clinical Decision Support (CDS) Hooks, REST APIs, and the architectural patterns that ensure clinical data is accessible, trustworthy, and performant at the moment of care. This role sits at the intersection of healthcare interoperability standards, modern API design, and operational excellence. You will establish reliability metrics and SLAs that ensure CDS Hooks and APIs serve clinician workflows with consistent quality and performance. You will be part of a small, high-performing healthcare engineering team where engineers support each other's growth through mentorship and tight collaboration.

Strong experience designing and operating REST APIs, including contract design, versioning, error handling, and authentication/authorization patterns
Deep understanding of healthcare data integrations, EMR workflows, and interoperability patterns (FHIR, HL7, CDS Hooks, SMART on FHIR)
Expertise in designing for reliability, SLAs, and operational metrics; ability to translate clinical requirements into technical SLOs
Experience defining and measuring API performance metrics (latency, availability, error rates); familiarity with SLA monitoring and enforcement
Strong systems thinking with ability to design for scale, reliability, maintainability, and resilience
Proficiency in modern backend languages (Python, Java, Go, or similar); comfort reading and reviewing code across languages
Experience with cloud platforms (AWS, Databricks, GCP) and containerized services (Docker, Kubernetes, or managed services)
Proven ability to partner effectively across engineering, product, analytics, clinical operations, and business teams
Clear written and verbal communication skills, particularly for explaining technical concepts and tradeoffs to clinicians and non-specialists
Comfortable working in a fast-moving, ambiguous environment with healthcare compliance and regulatory constraints

Responsibilities

Lead design and implementation of the CDS Hooks platform, including card orchestration, hook context handling, EHR-side logic orchestration, and integration with downstream data services
Own CDS Hook API contracts and evolution, ensuring compliance with SMART CDS Hooks specification while adding performance, reliability, and healthcare-specific optimizations
Lead technical integration with EMR systems (Epic, NextGen, Athena, ECW) for CDS Hook discovery, execution, card rendering, and user action handling
Design, build, and maintain public-facing REST and event-driven APIs exposing clinical data, quality metrics, care gaps, attribution data, and decision support content to partners and provider-facing applications
Establish API contracts, versioning strategies, and deprecation policies that balance innovation with stability for external consumers
Implement and maintain API security patterns including OAuth 2.0, scope-based authorization, rate limiting, and audit logging for compliant clinical data access
Design and optimize real-time or near-real-time data pipelines feeding CDS Hooks and APIs—ensuring low latency, high freshness, and graceful failure modes
Design and implement comprehensive testing and QA frameworks for CDS Hooks and APIs — including hook context validation, card rendering verification, and clinical workflow testing across EMR systems
Establish reliability metrics and SLAs (latency, availability, freshness) for CDS Hook delivery and API performance; measure and track against clinical requirements
Define and measure clinical impact metrics — adoption of CDS Hooks, clinician interaction rates, workflow integration success, and patient outcome influence
Exercise architectural judgment across tradeoffs in correctness, latency, scalability, maintainability, and operational risk in clinical data systems
Design and implement reliability patterns for CDS and API services including monitoring, alerting, failure detection, graceful degradation, and incident recovery
Partner with Data Reliability Engineer to define and operate SLAs for CDS Hook delivery, API response times, and data freshness aligned to clinical needs
