Data Engineer

We are looking for a highly motivated Data Engineer to join a small and growing team at a high-performing trading firm. This role is ideal for those who want to see tangible impact from their work. You will be collaborating directly with quants and portfolio managers to architect data flows and build resilient ETL systems that power real-time decision-making.

This is not a back-office or purely maintenance role. You will help shape how the firm ingests, processes, and leverages data across multiple strategies. The position offers significant ownership and influence for engineers who enjoy seeing the direct results of their technical contributions. This is a rare opportunity.

We are especially interested in candidates who prefer working on-premises infrastructure, value clarity and performance in their code, and have strong instincts around data reliability and system orchestration.
