Windows Identity Systems Engineer

Windows Identity Systems Engineer 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 , 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  
• Good understanding of identity, SSO and authentication
• Experience with PKI / certificates / certificate authorities
• Strong Azure security knowledge
• Good Power Shell / 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.

Full discretion assured.
