• Working knowledge of core authentication protocols (Kerberos, PKI, OIDC, FIDO2) and hands-on experience with mainstream identity systems (Active Directory, ADFS, ADCS, and Entra ID).
• Experience with passwordless authentication platforms (Windows Hello, YubiKeys, Passkeys) is highly preferred.
• The ability to guide the integration of IAM capabilities with other services, including prototyping where necessary; advanced coding skills aren't required.
• Excellent communication and collaboration skills, with the ability to advise on IAM strategy and work closely with teams across the firm.
