Backend Engineer

As a Backend Engineer at RevAI Pro Platform, you will be responsible for designing and building high-performance microservices in FastAPI (Python) and Node.js (TypeScript). You will develop and maintain REST / GraphQL APIs consumed by multiple modules and agents, implementing a multi-tenant architecture with PostgreSQL (RLS) and Redis for session and cache management. Additionally, you will build event-driven services leveraging Azure Event Hubs / Kafka for real-time workflows, own backend deployment, scaling, and reliability on Azure Kubernetes Service (AKS), and integrate OPA / Kyverno policy enforcement and audit logging for secure and compliant execution. You will also implement observability and automation using ArgoCD, Grafana, and Terraform while collaborating closely with frontend, AI, and product teams to deliver intelligent automation experiences.
