Security Engineer – Network & Identity

The Security Engineer (Network & Identity) is a hands-on engineering role within the IT team responsible for designing, implementing, securing, and automating Sungrow USA's network security, PKI and certificate management, and identity & access infrastructure across on-premises, cloud, and SaaS environments. This role serves as the technical owner for network security architecture, cryptographic services, certificate lifecycle management, authentication, and access controls. The position focuses on Zero Trust security, network segmentation, certificate-based authentication, and identity protection to reduce organizational risk and enable secure business operations and platform ownership rather than SOC operations, threat monitoring, or incident response.

Essential Duties And Responsibilities

Network Security

• Design, implement, and maintain secure enterprise network architectures across corporate offices, data centers, cloud platforms, and remote workforce environments.
• Architect network segmentation, Zero Trust access controls, and secure connectivity standards using Fortinet and Zscaler security solutions.
• Develop and maintain Zero Trust architectures across network, identity, endpoint, application, and cloud environments.
• Design and administer secure remote access using Zscaler Private Access, VPN technologies, and identity-aware access controls.
• Manage firewall policies, network security controls, routing security, DNS security, and hybrid-cloud connectivity.
• Design and support Network Access Control architectures using IEEE 802.1X, RADIUS, and certificate-based authentication.
• Assess network security posture, develop remediation plans, and drive continuous security improvements.

Cryptography, PKI & Certificate Management

• Own the enterprise PKI, cryptography, and certificate lifecycle management architecture, standards, and governance program.
• Design and manage certificate-based authentication and machine identity solutions for users, devices, servers, applications, cloud workloads, and network infrastructure across Azure, AWS, and hybrid environments.
• Implement and maintain certificate lifecycle automation using Microsoft Cloud PKI, Keyfactor, CyberArk Certificate Manager, EJBCA, DigiCert, AppViewX, or comparable platforms.
• Manage certificate issuance, enrollment, discovery, deployment, monitoring, renewal, revocation, auditing, and compliance across the enterprise.
• Design and support cryptographic services and certificate-based security controls, including TLS/mTLS, code signing, PKI trust hierarchies, certificate-based authentication, SCEP, PKCS, and machine identities.
• Establish PKI and cryptographic standards, key management practices, and security controls to support Zero Trust, regulatory compliance, and enterprise security requirements.
• Troubleshoot and resolve complex certificate, cryptographic, trust chain, authentication, and secure communications issues across enterprise systems and applications.

Identity & Access

• Define authentication and authorization standards for workforce, partner, application, service, and machine identities.
• Design, implement, and maintain Microsoft Entra ID architecture, tenant governance, and identity security controls.
• Develop, test, and enforce Conditional Access policies and Zero Trust access controls.
• Implement and maintain MFA, passwordless authentication, phishing-resistant authentication, and Microsoft Entra ID Protection capabilities.
• Design and support enterprise SSO and federation integrations using SAML, OAuth 2.0, OpenID Connect, and SCIM.
• Implement least-privilege and risk-based access models across enterprise platforms.
• Administer RBAC, administrative separation, Microsoft Entra Privileged Identity Management, and least-privilege access controls.
• Govern application registrations, service principals, enterprise applications, API permissions, and managed identities.
• Support B2B collaboration, guest-user governance, external workforce access, and third-party identity integrations.
• Design and implement security controls across Microsoft Azure and AWS environments.
• Apply least privilege, RBAC, encryption, secrets management, and secure configuration standards to on-prem and cloud resources.
• Automate identity provisioning and deprovisioning, access governance, certificate management, configuration validation, and security operations.
• Create reusable secure-by-default templates and reduce manual administration through automation and orchestration.
• Conduct access reviews, entitlement certifications, and identity governance activities.
