Elastic Platform Engineer

We tackle the most complex problems in quantitative finance, by bringing scientific clarity to financial complexity. From our London HQ, we unite world‑class researchers and engineers in an environment that values deep exploration and methodical execution – because the best ideas take time to evolve. Together we’re building a world‑class platform to amplify our teams’ most powerful ideas.

As part of our engineering team, you’ll shape the platforms and tools that drive high‑impact research – designing systems that scale, accelerate discovery and support innovation across the firm.

We’re looking for an Elastic Platform Engineer to manage and evolve the Elastic SIEM and Tines infrastructure within our Security Engineering team. In short, you’ll be the brain behind Elastic and Tines at G‑Research. You’ll ensure stability, scalability and security of the platform while planning and executing upgrades, patches and integrations.

As a senior engineer, you’ll mentor junior colleagues and contribute to the cross‑skilling of the wider Security Engineering function, including support for the Azure Logging platform when required. You will report into the Security Engineering Manager and play a key role in enabling the CSIRT Team to perform effective security monitoring and incident response across G‑Research’s cloud, hybrid cloud and corporate environments.
