Identity Security Architect – Kerberos & Authentication Discovery

Eames Consulting – London (Hybrid)

£660/day (Inside IR35)

We’re looking for an Identity Security Architect with deep Kerberos and IAM/password lifecycle expertise to lead a focused discovery of our authentication landscape. You’ll assess current-state architecture, uncover risks, and design clear, logical recommendations to strengthen authentication and password management across a complex enterprise.

Key Responsibilities

Lead a structured discovery of authentication, Kerberos, and password management processes.
Analyse and document existing Kerberos implementations across AD, Windows, and Linux.
Map application and service dependencies, highlighting gaps and architectural risks.
Review password-reset flows, service account behaviour, and identity lifecycle processes.
Evaluate SPN hygiene, delegation models, ticket lifetimes, encryption types, and trust relationships.
Produce concise, high-quality architecture documentation and remediation recommendations.
Work with technical teams to validate findings and support Kerberos integrations.
Define clear, repeatable processes for authentication and password management.

Essential Skills & Experience

Deep, hands-on Kerberos expertise (SPNs, delegation, ticketing, trusts).
Strong background in identity security architecture and authentication design.
Practical experience with password reset and IAM lifecycle processes.
Skilled with troubleshooting tools (klist, setspn, Wireshark, event logs).
Excellent analytical thinking and documentation—able to break down complex systems logically.
Strong communicator comfortable engaging both technical and non-technical teams.

Desirable

Experience in government or regulated environments.
Familiarity with IAM platforms, password management, or privileged access tools.
Background in authentication risk analysis and remediation planning.
