Lead Engineer in London

The Cyber Security Engineering Privileged Access Management team are looking for an independent, pro-active, and aspiring individual who is committed to making a meaningful contribution as a Lead Engineer to lead in the design, implementation, and lifecycle management of enterprise-grade PAM solutions across multi-site and multi-cloud environments (AWS, Azure, GCP). You’ll serve as a technical authority for PAM, shaping standards, delivering sophisticated migrations, and ensuring privileged access is secure, auditable, and resilient.

Key Responsibilities

• Design and implement PAM capabilities (vaulting, session management/recording, credential rotation, least privilege, EPM/PRA) across on-prem and cloud workloads.
• Lead complex integrations with AD/EntraID, IdPs, SIEM/SOAR, CSPM, ITSM, DevOps tooling (CI/CD), and secrets management.
• Be responsible for the operational model: backup/recovery, DR, platform upgrades, policy hardening, performance tuning, and continuous improvement.
• Drive onboarding at scale ensuring standardized onboarding patterns and controls.
• Establish guardrails and RBAC/ABAC models aligned to Zero Trust and regulatory frameworks (ISO 27001, SOC 2, NIST 800-53/63).
• Define and maintain technical roadmaps, standards, and reference architectures; mentor engineers and review develop/runbooks.
• Lead security assessments, threat modeling, and control efficacy reviews; partner with risk/compliance and audit functions on evidence and remediation.
• Solve complex issues end-to-end, including proxy/connector components, high-availability clusters, and multi-region architectures.

Technical / job functional knowledge

• Consistent record implementing and operating PAM at scale in complex enterprises (multi-site, multi-cloud).
• Hands-on expertise with at least one of the top PAM vendors (e.g., CyberArk, Delinea, BeyondTrust, One Identity), including deployment, integration, and automation.
• Solid understanding of Windows/Linux administration, AD/EntraID, networking and database fundamentals (TLS/PKI, proxies, firewalls), and identity protocols (SAML/OIDC/OAuth).
• Automation proficiency (PowerShell, Python, REST APIs) and Infrastructure-as-Code (Terraform/CloudFormation) for repeatable deployments.
• Experience with SIEM (e.g., Splunk, Sentinel, QRadar) and SOAR integrations for session telemetry, alerts, and response.
• Proven leadership in defining standards, runbooks, and governance; excellent customer engagement and interpersonal skills.

Additional desired capabilities

• Experience with endpoint privilege management (Windows/macOS/Linux), JIT access, and Kubernetes/containers.
• Exposure to segmentation and network security (micro-segmentation, PAM proxies, bastion hosts).
• Relevant certifications (e.g., CyberArk Defender/Sentry, Azure/AWS Security, CISSP, CCSP).
