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
