London | Industry-leading compensation (discussed on call)
Quant Capital is leading the search for a Windows Identity Systems Engineer for one of the most technically respected firms in the trading space.
This is a hands-on identity engineering role focused on securing and improving identity across a hybrid Microsoft environment spanning Active Directory, Entra ID, Microsoft 365 and Azure. The work centres on authentication, access control, PKI, identity hardening, automation and reducing attack paths across the platform.
What you’ll do
* Engineer and improve identity security across a hybrid Microsoft estate
* Strengthen authentication and access controls across on-prem and cloud environments
* Support PKI, certificate services and identity-related security controls
* Build and improve automation across the identity platform
* Identify security gaps and help improve controls across the wider identity environment
What they’re looking for
* Strong Active Directory and Entra ID experience
* Good understanding of identity, SSO and authentication
* Experience with PKI / certificates / certificate authorities
* Strong Azure security knowledge
* Good PowerShell / automation capability
* Background in identity engineering, Microsoft infrastructure or platform security
This is not a governance-led IAM role. It is a systems-focused identity engineering position, best suited to someone who enjoys solving technical identity problems properly and working in an environment that relies heavily on engineering and in-house build rather than off-the-shelf tooling.
