About Us
Aivra Health provides end-to-end revenue cycle management (RCM) for healthcare practices — medical billing, coding, claims processing, denial management, and reporting. Our platform ingests clinical and demographic data, generates compliant claims (ICD-10, CPT, HCPCS), submits them to clearinghouses and payers, and tracks remittances — all under HIPAA. You'll write the services that move that data accurately and fast.

Job Summary
We're hiring a Junior Software Engineer (0–4 years, recent grads welcome) to build and maintain the Python- and Java-based backend services behind our billing and claims platform. You'll own well-scoped features end to end with mentorship from senior engineers.

• Model and query relational data in **MySQL / SQL Server** — write performant SQL, design schemas and indexes, and manage migrations (e.g., Alembic / Flyway).
• Implement asynchronous and batch processing for high-volume claim runs using message queues or task workers (e.g., SQS, RabbitMQ, Celery).
• Write unit and integration tests (pytest, JUnit) and contribute to CI/CD pipelines (GitHub Actions) for automated build, test, and deploy.
• Containerize services with **Docker** and help run them on **AWS or Azure**.
• Enforce secure handling of PHI: role-based access control (RBAC), encryption in transit and at rest, audit logging, and least-privilege access.
• Participate in code reviews, sprint planning, stand-ups, and retrospectives.
