Python Backend Developer

Must-Have:
● 5+ years backend engineering experience, with deep expertise in Python 3.10+.
● Mastery of AsyncIO: You understand the Python event loop inside out. You know how to write non-blocking code that handles concurrent WebSocket connections efficiently.
● API Design Excellence: You build clean, RESTful (or GraphQL/RPC) interfaces that frontend teams love to use. You use Pydantic and strict typing to enforce contracts.
● Database Design: You are comfortable writing complex SQL queries and designing normalized schemas in PostgreSQL/SQLAlchemy.
● Architectural Pattern Knowledge: You understand State Machines, Event-Driven Architecture, and how to decouple services cleanly.

Nice-to-Have (But DevOps handles the heavy lifting):
● Familiarity with containerization (Docker) — you know how to build your app for production, even if you don't manage the cluster.
● Experience with FastStream or RabbitMQ.
● Understanding of WebSocket scaling patterns (Redis Pub/Sub)
