• Design data models and optimize performance on PostgreSQL and other data stores
• Build and deploy cloud-native services on Google Cloud Platform using Docker, GKE, Cloud Run, and CI/CD pipelines
• Ensure the platform meets healthcare security and privacy standards (HIPAA, PHIPA, SOC 2) through secure coding, encryption, audit logging, and access controls
• Write clean, well-tested code and participate in code reviews, architecture discussions, and technical design documents
• Mentor junior and mid-level engineers and help raise engineering standards across the MediCore team
• Work with implementation teams to troubleshoot issues and support go-lives with health system and clinic customers

• Hands-on experience with Google Cloud Platform (GCP), including services such as Cloud Run, GKE, Cloud SQL, Pub/Sub, and Cloud Storage, plus containerization with Docker
• Experience designing and consuming APIs and building event-driven or asynchronous systems (Pub/Sub, Celery, Kafka, or similar)
• Strong understanding of authentication/authorization (OAuth2, OIDC, SSO) and data protection
• Experience with automated testing (pytest, Jest, Playwright/Cypress) and CI/CD tools (Cloud Build, GitHub Actions, GitLab CI, or similar)
• Excellent communication skills and comfort working with non-technical stakeholders
• Spanish Language Proficiency

Nice to Have

• Healthcare technology experience, especially with HL7, FHIR, or EHR integrations
• Familiarity with HIPAA, PHIPA, or other healthcare compliance frameworks
• Experience building LLM-powered features, ideally with Vertex AI and Gemini, including RAG pipelines, vector databases, or AI agents
