New Listing

The Role

Seeking a highly motivated and experienced engineer to join the Risk Data Tech team. You’ll have the chance to boost your career in a fast-paced and ambitious team that strives to create state-of-the-art tools for a range of data-related activities, including onboarding, analysis, sourcing, quality checking, and lifecycle management. This fund doesn’t just have a standard data warehouse – their data estate is varied and highly optimised to deliver the needs of the business. Your challenges will be varied, involving:

  • Developing and maintaining core tools for analysts, quants, and engineers to on-board and analyse datasets at multi-terabyte-scale.
  • Collaborating with Risk Officers and with other Engineering teams to design and develop solutions for Risk for the whole company or for specific needs for an engine or a strategy.
  • Collaborating with Data Engineering team as they design and develop unique, bespoke solutions to solve big data challenges – they work on 200 Terabyte of data and own the main services that onboard vendor Risk data to support investments.
  • Designing and implementing strategies and tools to monitor and validate the data quality and data processing.

The Technology

Core systems are almost all running on Windows and most of the code is in .NET (C#). The first data storage is in SQL Server and they’re starting to use ArcticDb for the largest datasets. Part of the work is also in Linux with Python code, using pandas and other libraries to support visualization and data processing.

The platform inherits from old tools and services, so they use many old technologies (Remoting, MSMQ, WCF, Winforms, WPF) while migrating to new tools (.NET Core 8, Kafka, REST APIs, React, Arrow Flight). Devops is based on Bitbucket and Teamcity (Jenkins for the Python stack), using Grafana + Prometheus for metrics collection. Parts of the services are being moved into Docker for containerisation and Kubernetes for container orchestration. The technology list is never static: they constantly evaluate new tools and libraries.
