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
