PKI Engineer

Are you a PKI Engineer ready for a new challenge?

Sopra Steria is delivering a unique solution from the ground up for the Defence sector. It integrates infrastructure and applications within highly secure, mission-critical environments. This is an opportunity to make a genuine impact, contribute to complex technical solutions, and work on a nationally significant programme that few organisations can offer exposure to.

In this role, you will provide PKI engineering and operational support across certificate management, template deployment, HSM administration, and PKI governance activities. You’ll work closely with technical teams across Windows, Linux, and web-based environments to support certificate and application requirements.

For someone motivated by purpose, scale, and technical complexity, this role offers the chance to contribute to outcomes that really matter.

What you will be doing:

• 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:

• Experience supporting enterprise applications and infrastructure with PKI integration requirements.
• Experience working in complex or regulated environments.
