About BMLL
BMLL is the leading independent provider of harmonised Level 3, 2 and 1 historical data and analytics across global equities, ETFs, futures and US equity options. We provide market participants with immediate access to granular T+1 order book data and advanced analytics, enabling them to accelerate research, optimise trading strategies, and better understand market behaviour. BMLL was acquired in 2025 by Nordic Capital, alongside minority shareholder Optiver, marking a joint commitment to accelerate the company's next phase of growth. We offer an inclusive and collaborative culture, a hybrid working environment that includes regular days in our London office, weekly team lunches, and a variety of out-of-hours social activities.
About The Role

The promise we make is that however a customer gets BMLL's data, they get it in the most efficient, cost-effective and timely manner possible. Performing that task is no mean feat, and requires overcoming a lot of obvious problems - but many more subtle ones. Our systems are engineered to a high standard. The technologies we use include cloud databases like Databricks and Snowflake, open table formats e.g., Delta and Apache Iceberg; Apache Airflow and Celery for data processing workflows. Most of our tooling is in Python and SQL, and everything we run internally runs on AWS.
