About the Role
In this opportunity as Lead Security Engineer, you will:
Act as the technical lead for security across application, cloud, and infrastructure. Set technical direction, make the key calls, own the shape and quality of the security backlog end to end, and serve as the point of escalation for complex security and remediation work, without direct line-management responsibility.
Design and build security controls across layers such as operating systems, container orchestration, CI/CD pipelines, cloud configuration, and network boundaries, to defend against sophisticated adversaries and insider threats.
Design new security processes and ways of working, revamping patching cycles and golden-image and base-image refreshes across cloud and on-prem, so the team can move quick without sacrificing safety.
Come to the table with ideas: identify where security and remediation processes can be improved, propose better approaches, and turn them into standards the team adopts.
Set the technical approach across the full security scope: application and open-source dependency fixes,



infrastructure patching, cloud configuration and guardrails, WAF, network isolation, and secrets and machine-identity management. Prioritize by risk in line with industry best practice such as CISA guidance (CISA KEV, CVSS/EPSS, and SLA-driven burndown), and champion adoption of AI-augmented security tooling, including SAST and SCA.
Raise the technical bar by reviewing fixes and mentoring engineers, and coordinate with the wider security team across regions to keep standards and priorities aligned across time zones.
Own clear reporting and metrics, and build the runbooks, standards, and escalation paths that make security a repeatable, auditable capability.
