G-Research is Europe’s leading quantitative finance research firm. We hire the brightest minds in the world to tackle some of the biggest questions in finance. We pair this expertise with machine learning, big data, and some of the most advanced technology available to predict movements in financial markets.

The role

G-Research’s work centres on forecasting financial markets.  To achieve this, we use an ever-growing amount of data and processing.  The Big Data Platform team builds the (primarily Spark- and Hadoop-based) platforms that are key to enabling these business-critical functions.

At such a scale, automation is key and with this role there is a significant focus on configuration management, orchestration, Infrastructure as Code and CI/CD.  In addition to this, G-Research is embarking on a transformational journey in how we deliver infrastructure using open source technologies.  We are investing heavily in a hybrid cloud platform on which to build the next generation of applications and distributed platforms and deliver development efficiencies.  This provides a unique opportunity to re-invent how we operate our big data ecosystem.

Key responsibilities of the role include:

  • Help shape and engineer the Big Data platform, ensuring it is scalable, stable, performant, and easy to use and maintain
