This role is within the London Commodities Risk Technology team, focussing on our front-office trading platform. This proprietary trading platform is currently going through an exciting re-engineering phase and we are seeking to build out the development team. This front-office risk system calculates large volumes of results data, so there are considerable challenges in data modelling, distributed processing & grid computing. Hence, we require a seasoned developer who can efficiently design and develop micro-services and components which can handle and process large amounts of data with optimal performance. The application the candidate will be developing is a highly-distributed Python-based micro-services platform that uses RabbitMQ for transport and Openshift/Kubernetes for deployment.

• Integration with other supporting libraries: Work on integrating other libraries such as Market Data, Trade Repository, Analytics into the Risk Platform.
• Continuous Learning: Stay updated with latest trends and developments in technology.

What we’ll need from you

Preferred Skills

• Understanding of the risk greeks, products (Options, Futures, Exotics) and market data (curves, fixings/settlements, etc) ideally within a commodities business context.
• Experience with Python and databases within a distributed micro-services architecture.
• Some experience of loosely coupled architectures and queuing technology, ideally RabbitMQ.
• Some experience of C# would be advantageous.
• Good software engineering skills e.g. SOLID, TDD etc.
• Experience in a CI/CD and Automated Deployment environment with tools such as OpenShift/Kubernetes, Jenkins, uDeploy.
