Purpose of Role looking for a highly experienced PKI Security Engineer to lead the design, implementation and phased rollout of a Certificate Lifecycle Management (CLM) platform across EMEA.
This will establish automated certificate discovery and lifecycle controls, integrate the platform with enterprise PKI and technology services, and progressively support post-quantum cryptography (PQC) risk assessment and remediation over the next 1-3 years.
What will this person be doing?
- Lead the end-to-end implementation and phased rollout of the selected CLM platform across EMEA, from design & pilot through production deployment & operational handover.
- Create & maintain a central inventory of certificates, keys, trust stores, issuing CAs, owners, dependencies, environments and associated business services.
- Integrate CLM with Microsoft AD CS, approved public CAs, HSMs, load balancers, network devices, Windows and Linux servers, cloud services, containers, Kubernetes, Dev Ops pipelines and enterprise applications.
- Automate certificate request, approval, issuance, deployment, renewal, revocation and decommissioning using ACME, SCEP, EST, APIs, agents and native connectors where appropriate.
- Design CLM architecture, trust boundaries, RBAC, service accounts, resilient components, security controls & operating processes aligned with our standards and change governance.
- Plan discovery and onboarding waves with application, infrastructure and entity stakeholders; identify certificate ownership & remediate orphaned, expired, weak or manually managed certificates.
- Define monitoring, alerting, dashboards, audit evidence, KPIs/KRIs and integration with security monitoring and IT service-management processes.
- Perform technical evaluation, testing and troubleshooting of CLM capabilities, connectors and integrations, including production-readiness and scalability assurance.
- Support cryptographic discovery and inventory for PQC, identify quantum-vulnerable algorithms and dependencies, maintain a risk-based remediation backlog and help develop migration plans over the next 1-3 years.
- Assess vendor and product crypto-agility, certificate and protocol dependencies, and readiness for NIST-standardised PQC algorithms & hybrid transition patterns.
- Produce & maintain HLD, LLD, runbooks, support procedures, standards, onboarding patterns, knowledge articles and operational handover documentation.
- Provide PKI/CLM SME guidance to application, infrastructure, cloud, Dev Ops, security, risk, audit & entity teams across EMEA.
