Design systems capable of handling continuous data streams from medical devices, remote monitoring platforms, APIs, and clinical systems.

Ensure platform architecture supports high availability, fault tolerance, disaster recovery, and long-term maintainability.

Design Kafka topic structures, partitioning strategies, consumer groups, and message retention policies.

Build producers and consumers capable of handling high-volume, mission-critical medical data.

Implement retry mechanisms, dead-letter queues, idempotent processing, and event replay.

Use schema management tools such as Schema Registry , Avro , Protobuf , or JSON Schema .

Design services that can handle duplicate, delayed, incomplete, or out-of-order messages.

Streaming Pipelines

Implement streaming pipelines using technologies such as:

- Kafka Streams
- Kafka Connect
- Spark Structured Streaming
- Redpanda or Confluent Platform

Monitor throughput, latency, lag, error rates, and data quality across streaming systems.

Cardiac & Clinical Data Processing

Develop pipelines to ingest, normalize, and process cardiac data such as ECG/EKG, telemetry, wearable-device data, Holter monitor data, or remote patient monitoring feeds.

Store raw data, processed data, clinical events, derived metrics, and generated reports in appropriate storage systems.

Support signal analysis, trend analysis, anomaly detection,



and clinical rule-based processing.

Collaborate with clinical, data science, AI, and product teams to transform medical requirements into reliable software systems.

Ensure traceability between source data, analysis results, generated reports, and clinical review workflows.

Design and implement backend services using languages such as Java, Go, C#, Python, or TypeScript .

Build secure and scalable APIs using:

- REST
- gRPC
- GraphQL

Develop microservices that support clinical workflows, data ingestion, analytics, reporting, and system integration.

Ensure backend services are observable, testable, secure, and production-ready.

Implement service-to-service authentication, authorization, and secure data exchange.

Data Storage, Reporting & Analytics

Design storage architectures for high-volume medical data, including raw files, structured metadata, time-series data, and generated reports.

Work with databases and storage technologies such as:

- MongoDB
- Redis
- Elasticsearch / OpenSearch
- Object storage such as S3, Azure Blob Storage, or Google Cloud Storage
- Data lakes or lakehouse architectures

Build reporting pipelines that generate clinically relevant summaries, analytics outputs, and audit-ready records.

Ensure data integrity, lineage, versioning, retention, archival, and retrieval.

Healthcare Compliance, Security & Governance

Ensure systems are designed and operated in accordance with healthcare privacy, security, and regulatory requirements.

Implement controls for protected health information and personally identifiable information.

Support compliance with relevant frameworks and standards such as:

- HIPAA
- GDPR, where applicable
- HITRUST
- SOC 2
- HL7
- FHIR
- DICOM, where applicable
- IEC 62304, where applicable
- ISO 13485, where applicable

Build audit logging, access controls, encryption, monitoring, and traceability into core platform services.

Collaborate with security, compliance, quality, and clinical teams to support regulated product development.

Cloud, DevOps & Production Operations

Deploy and manage services in cloud, hybrid, or on-premise medical environments.

Use infrastructure and DevOps tools such as:

- AWS, Azure, or Google Cloud
- Docker
- Terraform
- GitHub Actions, Azure DevOps, Jenkins, or similar CI/CD platforms

Implement production monitoring, alerting, logging, tracing, and incident response processes.

Support service reliability, uptime, disaster recovery, backup, and business continuity requirements.

Participate in architecture reviews, deployment planning, production support, and root-cause analysis.

Required Qualifications

5+ years of experience managing or engineering software systems in medical, healthcare, clinical, digital health, medical device,



remote patient monitoring, or life sciences environments.

Strong hands-on experience with Apache Kafka or comparable event-streaming platforms.
