Senior DevOps / Platform Engineer - Autonomous Vulnerability Research (Harness Engineering)

In this role you will design, build and operate a Kubernetes-based platform for autonomous vulnerability research at scale, enabling secure, auditable AI-powered workloads. You will own IaC across GCP, implement hardened container/VM images, and enforce strict egress and segmentation to ensure safe research. You’ll collaborate with AI Engineering and Security Architecture to demonstrate control effectiveness, while accelerating researcher velocity within a security-first culture. This is a hands-on, platform-building role that drives secure, scalable research capabilities at Lloyds Banking Group.
