Senior PKI Engineer — Certificate Authorities, HSMs and Smart Cards for NATO with security clearance

Every secure login, signed document and trusted connection across a largeinternational organisation rests on its public key infrastructure. A multinational defenceorganisation is looking for a senior engineer to run that infrastructure day to day, design whatcomes next, and be the person other teams escalate to when certificates stop behaving.

What you would be doing

• Installing, configuring and maintaining the organisation-wide public key infrastructure andevery component it depends on — virtualised platform, networking, hardware.
• Running the directory service and its supporting web service, and keeping the dedicateddatabases healthy.
• Owning certificate status checking and time stamping, so that revocation actually takeseffect.
• Deploying, integrating and managing the card management system, and supporting smart cardenrolment and certificate issue.
• Managing hardware security modules, including firmware upgrades.
• Analysing certificate authority logs: troubleshooting alarms and errors, and watching activityfor what should not be there.
• Keeping daily operations, backup and restore in order, and proving the restore works.
• Providing second and third line technical support to the operating authorities and thecustomers of the service.
• Designing new components, writing the standard operating procedures that go with everychange, and documenting new services properly.
• Investigating network faults, security incidents and performance problems, and carrying theimprovements through to implementation.
• Supporting the integration of security tooling into current and future environments, andrunning the testing, validation and acceptance that goes with it.
• Writing the technical documentation the next engineer will need: installation guides,configuration baselines, test plans and reports, hardening guides.
• Working with project managers, engineers, architects and operational stakeholders, andhanding over to operations with the knowledge transfer that makes a handover real.
• Being willing to work outside office hours when an incident or an operational requirementasks for it.

What you would bring

• At least five years in cyber security or a closely related field — building securityarchitecture, delivering security capabilities, or running demanding technical estates.
