SCOPE OF WORK:

Manage and operate certificate lifecycle management processes, including issuance, renewal, revocation, replacement, auditing, and compliance tracking.
Integrate, configure, and maintain Certificate Management Systems (CMS) and enterprise‑wide enrollment services.
Implement and maintain automation workflows for certificate management using ACME and other certificate automation protocols.
Operate and maintain PKI environments across hybrid cloud and on‑prem infrastructures, including Microsoft CA, EJBCA, and other open‑source or commercial PKI systems.
Manage Hardware Security Modules (HSMs), including key generation, protection, rotation, backup, and secure handling of cryptographic materials.
Support Identity Providers (IdPs) and authentication frameworks, enabling secure integration with SSO, MFA, federation protocols (SAML, OIDC, OAuth2), and certificate‑based authentication.
Manage and enhance auto‑enrollment mechanisms for certificates on servers, devices, applications, and user endpoints.
Develop automation scripts (PowerShell, Python) for certificate deployment, renewal workflows, system integrations, and reporting.
Support secure onboarding/offboarding of services requiring certificates, ensuring proper identity binding, policy enforcement, and trust‑chain validation.
Understand and manage interactions with public Certification Authorities (CAs), including validation processes (DCV/OV/EV), documentation handling (CSRs, legal/organization proofs), issuance tracking, and compliance with CA/B Forum and vendor requirements.
Assist security operations by providing PKI expertise for incident response, including mis‑issuance, certificate‑related outages, or key compromise scenarios.
Maintain documentation of PKI architectures, baselines, approval workflows, system configurations, key ceremonies, and operational procedures to ensure consistency and business continuity.
Provide support for internal and external audits, including preparation of evidence related to certificate usage, access control, cryptographic operations, and compliance posture.
Contribute to the development of training and awareness materials to strengthen organizational understanding of PKI, secure authentication, and certificate management.

The resource MUST have the following skills and experience:

Strong understanding and hands‑on experience with federation protocols (SAML, OAuth2, OIDC), SSO models, IdP integrations, and identity brokering.
In‑depth knowledge of Multi‑Factor Authentication (MFA) and certificate‑based authentication workflows, including integration with enterprise identity platforms.
Extensive experience with certificate‑based authentication, encryption, digital signatures, and secure identity binding across enterprise environments.
Solid experience with PKI and certificate management systems such as EJBCA, Microsoft CA, and public Certification Authorities (Entrust, DigiCert, Sectigo), including validation processes (DCV/OV/EV) and associated documentation.
Strong knowledge of certificate lifecycle management, including issuance, renewal, revocation, CRLs/OCSP, enrollment protocols, trust‑chain validation, and policy enforcement.
Practical experience with certificate automation protocols, including ACME and other automated enrollment mechanisms.
Proficiency in scripting and automation (PowerShell, Python, Bash) for certificate workflows, integrations, monitoring, and lifecycle orchestration.
Experience with Hardware Security Modules (HSMs) for secure key generation, lifecycle management, storage, and cryptographic operations.
Familiarity with Zero Trust principles relevant to identity assurance and certificate‑driven access control.
Excellent communication, collaboration, and documentation skills.
Ability to work independently, proactively report progress, and operate with minimal supervision.

The resource SHOULD have the following skills and experience:

Experience with authentication and authorization processes that integrate certificate‑based access models (e.g., policy‑driven access, EKUs/Key Usage constraints, smartcard/PIV workflows).
Familiarity with credential vaulting or access control tools, such as CyberArk, in contexts where certificates or cryptographic keys are used for authentication.
