Job description

Welcome to Waymark. We are a mission‑driven team of healthcare providers, technologists and builders working to transform care for people with Medicaid benefits. Our community‑based care teams—powered by proprietary data science and machine learning technologies—support tens of thousands of Medicaid members across multiple states, driving measurable reductions in avoidable emergency department visits and hospitalizations. We’re designing tools and systems that bring care directly to those who need it most, removing barriers and reimagining what’s possible in Medicaid healthcare delivery.

This is a senior‑to‑principal level, individual contributor role that combines deep backend engineering fundamentals with specialized expertise in Electronic Health Record (EHR) data integration. You will report to data engineering leadership and set the technical direction for our clinical data platform by designing, developing and optimizing data pipelines that ingest, normalize and transform clinical data from diverse EHR and payer systems.

Key Responsibilities

EHR & Partner Integrations

• Architect production‑grade data pipelines that integrate clinical data through multiple channels—direct EHR connections (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, enforcing healthcare standards and clinical terminologies (ICD‑10, SNOMED CT, LOINC, RxNorm) and targeting sub‑hour latency from clinical event to actionable insight with ≥99.9% 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 (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—reducing new‑partner integration time by 50% or more while improving developer productivity and reducing operational toil.

ML/AI Enablement & Product Collaboration

• Partner with data science and analytics teams to build and operationalize 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 their implementation.

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 a 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 (e.g., 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 relational (PostgreSQL) and columnar/analytical databases (Redshift).
• Experience with containerization and orchestration technologies (Docker required, Kubernetes).
  Design data integration systems resilient to inconsistent, incomplete and delayed clinical data across heterogeneous EHRs and payer systems directly or via 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.
