We are hiring a Python Backend Engineer to take ownership of high-throughput backend services. You will work alongside our front-end and C# application teams to build the infrastructure that ingests, processes, and routes real-time data streams across our platforms.
This role is for someone who enjoys asynchronous Python, complex data-flow problems, and the discipline of building production systems that need to run reliably under sustained load.
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.
