Backend Python Developer (2–3 Years)

Join our backend team to architect and scale low-latency FX trading services.

You’ll build FastAPI
microservices, model real-time market data in PostgreSQL, and engineer an idempotent stream
consumers across Kafka/Redpanda/RabbitMQ/SQS.
■ Responsibilities
• Develop & maintain FastAPI microservices (auth, market ingestion, order flow, reporting)
• Design PostgreSQL schemas for tick/quote/OHLCV data
• Implement UPSERT logic with deduplication & idempotency
• Build queue/stream consumers with robust exactly-once/at-least-once semantics
• Optimize: async I/O, connection pooling, indexing, partitioning
• Write resilient tests (e.g., property-based for rounding, contract tests for APIs)
• Deploy observability: metrics, logs, tracing, alerting
✔■ Must-Have Skills
• 2–3 years of Python in production (FastAPI, async, typing, Pydantic)
• Solid PostgreSQL knowledge (indexes, query plans, partitioning, ACID/transactions)
• Strong with stream/queue systems (Kafka, RabbitMQ, SQS)
• Proven track record of idempotent upserts & retry-safe processing
• Proficiency with Docker, Git, CI/CD pipelines
■ Nice-to-Have
• Experience with FX/market data (ticks, OHLCV, timezones, rounding)
• ETL tools (Pandas, NumPy, Arrow), Redis, K8s, Terraform
• Security-aware (authN/authZ, rate-limiting, secret handling)
■ Stack You’ll Touch
• Python 3.11+
• FastAPI, Pydantic
• PostgreSQL 14+
• Kafka/Redpanda (or RabbitMQ/SQS)
• Docker, pytest
• Prometheus, Grafana
