**Posted:** 2026-05-08

> Designs and leads production data pipelines integrating EHR clinical data from Epic Cerner Athenahealth via FHIR HL7 CCDA enforcing healthcare standards for low-latency insights. Builds AWS cloud infrastructure ETL workflows with Python Docker Kubernetes for ML enablement and HIPAA compliance requiring 5+ years healthcare data engineering experience.

## Job Description

## Key Responsibilities

### EHR & Partner Integrations
- Architect production-grade data pipelines that integrate clinical data through multiple channels—direct EHR connections (e.g., Epic, Cerner, Athenahealth), health information exchanges (HIEs), health alliance networks, and third-party integration vendors—via **FHIR R4 APIs**, **HL7v2 feeds**, **CCDA documents**, and bulk data exports, while enforcing healthcare standards and clinical terminologies (**ICD-10**, **SNOMED CT**, **LOINC**, **RxNorm**), targeting sub-hour latency from clinical event to actionable insight and ≥99.9% pipeline reliability
- Lead end-to-end integration efforts with health plan partners, HIEs, health alliance networks, provider organizations, and data integration vendors—owning partner technical evaluation, connectivity, data mapping, validation, and production rollout

### Data Platform & Tooling
- Build and optimize cloud-native data infrastructure (**AWS**) and ETL/ELT workflows using modern orchestration tools (e.g., **Step Functions**, **dbt**) with robust data quality monitoring and lineage tracking
- Develop reusable backend frameworks, libraries, and internal tooling that accelerate onboarding of new data sources—whether direct EHR feeds, HIE connections, or vendor integrations—with the goal of reducing new-partner integration time by 50% or more while improving developer productivity and reducing operational toil across engineering

### ML/AI Enablement & Product Collaboration
- Partner with data science and data analytics teams to build and operationalize the data foundations for predictive risk scores, care gap identification, clinical alerting, and patient outreach prioritization
- Collaborate with product and clinical teams to translate care delivery requirements into scalable, production-grade technical solutions and influence

### Security & Compliance
- Ensure all data systems comply with **HIPAA**, **HITECH**, and applicable privacy regulations, implementing access controls, audit logging, encryption, and de-identification processes for PHI

### Leadership & Mentorship
- Provide technical leadership and mentorship to engineers across Waymark, raising the bar on healthcare data best practices

## Qualifications

### Must-have
- Significant software engineering experience with substantial focus on healthcare data engineering or EHR integration (**Senior: 5+ years; Principal: 8+ years**)
- Expert-level proficiency in **Python** (required) and experience in at least one compiled or concurrent language (such as **Elixir**)
- Deep understanding of distributed systems, cloud computing, and backend system design: API architecture (**REST**), microservices, event-driven systems, message queues (**RabbitMQ**), caching strategies, and distributed systems patterns
- Strong background in data modeling, schema design, performance optimization, and both relational (**PostgreSQL**) and columnar/analytical databases (**Redshift**)
- Experience with containerization and orchestration technologies (e.g., **Docker** (required), **Kubernetes**)
- Design data integration systems resilient to inconsistent, incomplete, and delayed clinical data across heterogeneous EHRs and payer systems either directly or through HIEs, health alliance networks, or integration vendors, using **FHIR APIs**, **HL7v2** interfaces, or **CCDA** parsing
- Strong experience in mapping/normalizing healthcare standards such as **ICD-10**, **SNOMED CT**, **LOINC**, **RxNorm**
- Strong communication skills, with the ability to explain complex technical concepts to both technical and non-technical audiences

### Additional Expectations for Principal (L4)
- Demonstrated track record of setting technical direction for complex platforms and influencing engineering strategy across multiple teams
- Comfort operating as a principal IC with broad influence and without direct reports—shaping roadmaps, standards, and architectural decisions
- History of leading the most ambiguous or highest-risk integration efforts end-to-end, including partner-facing technical leadership

### Nice-to-have
- Advanced degree in Computer Science, Software Engineering, or a related field
- Experience working in value-based care, population health, or Medicaid/Medicare data environments
- Experience with ML/AI frameworks (**TensorFlow**, **PyTorch**) and MLOps practices for healthcare applications
