• Contribute to CI/CD pipeline improvements using GitLab CI/CD, including build, test, containerization (Docker), and deployment automation to GCP environments. 
• Engage proactively in the triage and resolution of escalated production issues — diagnosing failures, investigating root causes, and driving durable fixes with a sense of urgency, clear communication to stakeholders, and a commitment to preventing recurrence. 
• Follow and comply with all security policies and procedures established by the organization, including adherence to HIPAA and HITRUST regulations  
• Applicants must be authorized to work for any employer in the US. This position does not offer sponsorship for employment visas. 

 Data Platform Domain Focus 

 Medecision's unified Data Platform is a multi-tenant, cloud-native system that ingests, standardizes, curates, and delivers clinical data (Member, Provider, Claims, Lab Results, Rx, and custom datasets) to power analytics, population management, and reporting for health plan customers. Key domain responsibilities include: 

• Own and evolve the end-to-end data ingestion pipeline: from SFTP/GCS file receipt through ingestion, standardization, curation, and load to BigQuery analytics datasets. 
• Design and implement custom dataset ingestion capabilities — including dynamic schema mapping, configuration-driven pipeline execution, and automatic BigQuery table/view provisioning on dataset activation. 
• Maintain and improve the Ingestion Event Service (IES). The platform's central tracking service for data ingestion progress — including Pub/Sub async processing and Firestore document management. 
• Implement FHIR R4 data ingestion workflows via Pub/Sub and GCP Healthcare Datasets, including XSD/schema validation and HL7 resource mapping. 
• Support population matching data flows, ensuring custom dataset filters integrate correctly with population builder services and BigQuery analytics queries. 
• Build and maintain reporting dataset views (BI-compatible BigQuery views) for tenant data exposure. 
• Integrate with third-party clinical analytics engines via GCE VM instance templates, Airflow DAGs, and GCS-based data exchange. 
• Ensure all data services meet HIPAA requirements: PHI handling, tenant data isolation, audit logging, and data classification.

 AI-Native Delivery (Required) 

 Medecision operates an AI-native SDLC. The Senior Software Engineer is expected to be a practitioner — not just a beneficiary — of AI-assisted delivery:  

• Demonstrate a solid understanding of AI concepts, capabilities, and limitations as they apply to software engineering workflows, including code generation, test scaffolding, and documentation. 
• Use Claude Code as a primary productivity tool for code drafting, refactoring, test generation, and technical documentation — applying it with judgment, rigor, and accountability. 
• Leverage AI-assisted workflows to accelerate implementation, surface edge cases, generate structured artifacts, and conduct at-scale analysis of service dependencies and API contracts. 
• Contribute to building and exposing MCP-wrapped APIs that enable AI agents to safely interact with platform services. 
• Maintain strict HIPAA discipline in all AI-assisted work: no real PHI in prompts or AI-generated artifacts; adhere to managed-settings policies and complete mandatory HIPAA + AI training. 
• Contribute to the team's shared AI knowledge base. Validated prompts, skills, and workflows — and participate in the AI Champions community of practice. 

What You'll Bring: 

 Required  

• Bachelor's degree in Computer Science, Software Engineering, Data Engineering, or equivalent practical experience. 
• 5+ years of data engineering or backend software engineering experience building production data pipelines and platform services. 
• Proven hands-on experience with Google Cloud Platform data services: BigQuery (schema design, partitioning, clustering, query optimization), Cloud Storage, Cloud Pub/Sub, Cloud Dataflow (Apache Beam), Cloud Composer (Airflow), Cloud Run, Cloud Functions, Firestore, Cloud SQL (PostgreSQL), and Secret Manager. 
• Strong proficiency in Java for data pipeline development 
• Proficiency in Python for Airflow DAG authoring, and automation scripting. 
• Experience designing and implementing batch and streaming data pipelines — including file-based ingestion, event-driven processing, deduplication, validation, incremental load, and full-reload patterns. 
• Proficiency with BigQuery data modeling: partitioned and clustered tables, dataset organization (standardized, curated, analytics, custom analytics, reporting layers), and SQL query optimization. 
• Experience with Apache Airflow / Cloud Composer — authoring, deploying, and maintaining production DAGs with parameterized configurations and robust error handling. 
• Experience with containerization (Docker) and deploying services to cloud-native environments.
