About the team Access Center (Comet) is Innovaccer's healthcare workflow platform. The stack spans a React/Redux frontend served through a Node.js layer, and a Python/FastAPI backend (with some legacy Django) using MongoDB, PostgreSQL, and Kafka, with growing use of LLM/AI agent tooling. It powers multi-tenant products used by live customer deployments daily. Responsibilities Build features across the stack: React/Redux on the frontend, Python/FastAPI services on the backend Design and integrate REST APIs, including rate limiting, retries, and idempotency for external integrations Model and query data across MongoDB, PostgreSQL, and Elasticsearch as needed Work with Kafka based event streams for cross-service communication Write unit and integration tests on both ends of the stack (Jest/React Testing Library on frontend, pytest on backend) Debug and triage production issues across the stack, using observability tools (OpenTelemetry, NewRelic) to find root cause Collaborate with product and design on features, and with QA on test coverage Contribute to CI/CD pipelines (GitLab CI) and Docker based deployments Apply secure coding practices,
