• Run PKI operations and engineering activities.
• Create, review, deploy, and manage certificate templates.
• Support certificate management across multiple platforms and applications.
• Work with engineers and technical teams to understand certificate, application, and infrastructure requirements.
• Assist in defining, documenting, and maintaining the Certification Policy Statement.
• Contribute to certificate lifecycle management processes, including issuance, renewal, revocation, and governance.
• Provide additional PKI engineering support where needed across project and operational demands.

What you will bring:

• Knowledge of DPKI / PKI.
• Experience in PKI architecture and engineering support.
• Experience working with HSMs, ideally Thales HSM products.
• Strong experience in certificate management and certificate template deployment.
• Experience managing certificate templates in enterprise environments.
• Good understanding of certificate lifecycle management and PKI governance.

It would be great if you had:
