London Hybrid, 1 day per week in the Liverpool Street office

This role is key to ensuring our products are robust, reliable and ready to deliver best‑in‑class insights to some of the world’s leading financial institutions.

What you’ll be working on:

About the Data Ingest Team:

The Data Ingest team is the oldest team at FXC Intelligence, existing in some form for over six years now. We provide the platform for collecting unstructured data from open third‑party websites and mobile apps, and make sure that the data collected corresponds to companies data quality standards and SLAs. As the business grows and requirements change, so do we – the platform has survived several iterations and is currently in the process of being migrated to its fourth generation.

• Knowledge of SQL and database testing

• Familiarity with Kafka or RabbitMQ

• Exposure to monitoring tools like ELK or Prometheus

Tech Stack:

Development: Python, Pytest, Pydantic, Pandas
