Requirements

Experience: 4+ years of professional backend software engineering experience, primarily in Python.

Asynchronous Python: Strong working knowledge of asyncio and concurrent programming patterns for high-throughput I/O.

API Frameworks: Production experience with FastAPI (or comparable async frameworks such as Starlette, aiohttp, or Sanic) and pydantic-based schema validation.

Message Brokers: Hands-on experience with at least one event streaming or message broker platform — Apache Kafka, RabbitMQ, NATS, or equivalent.

Databases: Proficient with PostgreSQL and capable of writing optimized SQL; comfortable with schema design, indexing, and query profiling.

Time-Series Data: Working familiarity with time-series databases (e.g., TimescaleDB, InfluxDB, QuestDB) and the trade-offs of heavy-write workloads. Networking: Solid grasp of TCP/UDP, WebSockets, and HTTP/REST; able to debug at the protocol level when needed.

Platform & Tooling: Comfortable Git-based workflows.

Testing & Quality: Demonstrated practice with pytest, unit and integration testing, and CI pipelines.
