IAM Platform Engineer - Identity, Entitlements & Authorisation

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.

Security is foundational to this mission and must be delivered in a way that supports how our engineering teams build and operate complex systems at scale.
