For more information, please visit our website, or visit our X, @bmlltech or LinkedIn, @BMLL. About the Role At BMLL we process financial data in a process we call parsing. We continually add new financial datasets to our platform whilst upgrading and improving existing ones. Parsing occurs in well defined data pipelines built using a distributed architecture. The engineering of the pipeline is as important as the data transformation process, and we are constantly working to improve its performance and reliability. We curate the data to ensure the highest quality of delivery to our customers. Every day we consume over 1TB of new data across 750,000 securities to deliver into our platform, our dashboard products and data services. These are accessed by our customers who are dependent on our services for their own workflows. The majority of our data processing code is written in C++, and Python is used extensively in orchestrating workflows and managing reference data. Both BMLL's business and the data production team have grown significantly over the last few years. Therefore we are sub‑dividing the team as we go into 2026, in order to specialise on asset classes. As such we are now looking for a new Market Data Team Lead to sit alongside two existing leads. You will take responsibility for the data production system relating to equities, which has long been the core of BMLL's offering. This will involve hands‑on development work, organising developers in Agile sprints, leading scrums, planning at the sprint level and at the quarterly level alongside Product Team, managing production support rotas, reporting on progress and blockers, and helping to unblock developers by working with other teams and providing guidance and technical expertise. You should expect to spend approximately 50% of your time in hands‑on development, and 50% in team management. All of this will involve working very closely with the two existing leads, the lead architect and Product and Operations Teams to build and maintain equities data parsers. These parsers ingest and process market data and reference data. You will look to improve processes and reliability for managing these large datasets using the latest AWS technologies, and become an expert in understanding the data and the way we curate and process it. This is an opportunity to join a cutting‑edge FinTech company with the potential to grow your technical, finance and cloud‑ & data‑engineering skills. Responsibilities
