• 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.

• Participate in code reviews, sprint planning, stand-ups, and retrospectives.

• 0-4 years of software development experience - internships, academic, or personal projects count for recent graduates.
• Solid programming fundamentals in Python and/or Java, with a willingness to ramp quickly on the other.
• Understanding of data structures, algorithms, and OOP.

Nice to Have

• Coursework, internship, or project experience with a web framework (FastAPI, Flask, Spring Boot, Django).
• Exposure to cloud platforms (AWS or Azure), Docker, or Linux.
• Experience with CI/CD, automated testing, or message queues.
• Any exposure to healthcare data standards (X12 EDI, HL7, FHIR) or other regulated/compliance-heavy domains - a strong plus, not required.
