Python Engineer - Market Data Platform

The Team

The Market Data Platform team is responsible for the data feeds that drive research and trading processes across Man Group. Tick data is our primary source of intraday market data, and we efficiently capture and store around 5bn ticks every day from a range of L1 feeds. We rely on a mix of external vendor products for other sources of market and reference data. From these sources we create pipelines that post-process data for investment use and build tooling and applications to manage the lifecycle of raw and derived data.

Man Group is investing heavily in faster trading strategies and algos that require access to lower latency and higher quality sources of tick data. The Market Data Platform team is a crucial part of this initiative, ensuring we have the technical capability to capture, store, manage and deliver that data, at petabyte scale.

The Role

We are looking for an experienced engineer to join the Market Data Platform team. It is an exciting time to join the team as we extend our tick data capabilities as well as ensuring our existing sources of market data are reliable and that the technology underpinning those is fit for purpose. Your challenges in the role will be varied and might include:

Working with real-time tick and historical data vendors and their technologies to ingest and distribute data at Man Group Contributing to the design of a low latency, high throughput tick data platform Generating high quality, intraday price datasets across multiple liquid asset classes Building tools for visualisation and management of datasets at terabyte scale Continually improving the reference data systems in use by systematic strategies Optimising the use of open-source technologies such as Kafka, ArcticDB and MongoDB

Our Technology

Our systems run on Linux and most of our code is in Python3, using the full scientific stack: e.g. numpy, scipy, pandas, scikit-learn. We implement the systems that require the highest data throughput in Java.

We use RMDS/TREP and Kafka for data pipelines, ArcticDB and MongoDB for storage, Bitbucket for source control, Jenkins for continuous integration, Prometheus + Grafana for metrics collection, ELK for log shipping and monitoring, Docker for containerisation, Kubernetes for container orchestration, Airflow for scheduling, OpenStack for our private cloud, Ansible for architecture automation, and Slack for internal communication. Our technology list is never static: we constantly evaluate new tools and libraries.
