The PKI / Certificate Management Engineer designs, deploys, and maintains a secure, scalable Public Key Infrastructure supporting enterprise, cloud, government, and hybrid environments. The role is responsible for automating certificate issuance and renewal, managing certificate lifecycles across Windows, Linux, cloud platforms, containers, applications, and network devices, and establishing governance and monitoring processes that reduce the risk of certificate-related outages.

This position supports the Zero Trust architecture through certificate-based authentication, encryption, workload identity, and secure communications. The engineer will also support Federal PKI and DoD PKI integrations, CAC/PIV authentication, mutual TLS, FIPS-validated cryptography, hardware security modules, and cloud-native certificate services in AWS GovCloud.

Job Responsibilities

• Design, implement, and maintain enterprise Public Key Infrastructure (PKI) supporting internal and external certificate requirements.

• Manage the full certificate lifecycle, including request, issuance, validation, distribution, renewal, revocation, expiration, and retirement.

• Implement and maintain ACME-based certificate automation and other automated enrollment and renewal workflows.

• Manage certificates across Windows, Linux, cloud platforms, containers, applications, load balancers, network devices, and other enterprise systems.

• Design and operate integrations with AWS Private Certificate Authority (AWS Private CA), AWS Certificate Manager (ACM), and related AWS services.

• Implement and administer Hardware Security Module (HSM) capabilities, including AWS CloudHSM, for secure protection of private keys and cryptographic operations.

• Support Federal PKI (FPKI) and DoD PKI trust relationships, certificate chains, and interoperability requirements.

• Integrate CAC/PIV authentication with enterprise applications, identity platforms, operating systems, and secure access workflows.

• Implement and maintain mutual TLS (mTLS) for workload identity, service-to-service authentication, and Zero Trust communications.

• Ensure cryptographic implementations use FIPS-validated cryptographic modules and approved algorithms where required.

• Establish certificate discovery, inventory, monitoring, and alerting capabilities to identify unmanaged certificates and prevent expiration-related outages.

• Develop governance standards for certificate ownership, issuance, naming, key length, cryptographic algorithms, renewal periods, revocation, and retention.

• Integrate certificate management with Identity and Access Management (IAM) platforms and authentication workflows.

• Support secure networking and communications through TLS, mTLS, certificate-based authentication, and encryption standards.

• Monitor PKI platform health, certificate status, revocation services, HSM operations, and certificate expiration events.

• Troubleshoot complex certificate-chain, trust-store, TLS, cryptographic, enrollment, renewal, and authentication issues.

• Partner with cybersecurity, identity, cloud, platform, network, and application teams to integrate PKI services into enterprise architectures and deployment workflows.

• Maintain PKI architecture documentation, certificate policies, operational procedures, runbooks, governance standards, and audit evidence.

Job Qualifications

• Bachelor’s degree in Cybersecurity, Computer Science, Information Technology, Information Systems, or a related technical discipline.
