■ 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
