PKI Architect

Job Summary We are seeking a hands-on PKI and Certificate Lifecycle Management CLM specialist to lead enterprise certificate modernisation while operating and improving a production CLM service The role combines architecture platform engineering lifecycle automation integration operational governance and delivery leadership Responsibilities The role must be equally comfortable designing a target state architecture administering AppViewX integrating with ServiceNow and Certificate Authorities writing automation troubleshooting incidents building runbooks and leading the controlled transfer of repeatable activities to a distributed delivery team Primary Outcomes Automate certificate discovery ownership request issuance renewal deployment revocation and evidence generation to reduce expiry risk and manual effort Establish an enterprise certificate inventory and reconciliation model across CLM platforms Certificate Authorities endpoints and the corporate CMDB Operate stabilise and continuously improve AppViewX while remaining capable of assessing and integrating other enterprise CLM and PKI technologies Deliver an MVP for priority public TLS certificate use cases and evolve the service toward a strategic internal and external PKI capability Create sustainable operating procedures automation controls service measures backup coverage and knowledge transfer so the service does not depend on one individual Key Responsibilities 1 PKI and CLM Architecture Lead currentstate assessment and targetstate design across public and private PKI Certificate Authorities CLM platforms
