Responsibilities

Work on a greenfield, on-premise Private Cloud Platform, helping shape the security foundations from day one and working closely with architects and engineers to build security into the platform. Lead threat modelling across the platform, identifying realistic attack paths and turning them into practical security requirements, controls and actions that engineering teams can implement.

Bring strong infrastructure security experience across private/hybrid cloud, virtualisation, containers, networking, IAM/PAM, PKI, segmentation and hardening, with a hands‐on approach to reviewing designs, configurations and technical implementations.

Build security into the engineering lifecycle through IaC, CI/CD, policy‐as‐code and automation, with a focus on automated control testing, continuous validation and generating clear, auditable security evidence. Work as the security partner to Engineering, defining reusable security patterns and production‐readiness standards, applying frameworks such as NIST and STIGs pragmatically and driving security findings through to resolution.
