Job Summary

We are seeking an experienced Integration & Security Architecture Engineer with strong expertise in Operational Technology (OT), industrial/plant networks, physical security systems, and security architecture.

The ideal candidate will have hands-on experience designing and integrating Physical Access Control Systems (PACS) within industrial and plant environments. This role requires a strong understanding of OT network architecture, network segmentation, industrial firewalls, physical security devices, API integrations, identity systems, cloud/hybrid architectures, and cybersecurity controls.

Important: This is an OT / Plant Network-focused position and NOT an IT Operations role. Candidates must demonstrate direct experience working with industrial/plant networks and Operational Technology environments.

Integrate PACS event feeds using platforms such as LenelS2 OnGuard OpenAccess, Genetec SDK, and C CURE APIs.

Integrate physical access control systems with HR and identity platforms, including Workday, Active Directory, and Microsoft Entra ID.

Design automated employee onboarding, offboarding, access provisioning, and deprovisioning workflows.

Required Skills

Strong OT / plant network experience in manufacturing or industrial environments.

Hands-on experience with PACS platforms such as Genetec, LenelS2 OnGuard, C CURE, or Pro-Watch.

Experience with REST APIs, webhooks, event streaming, and OAuth 2.0.

PACS integration with Workday, Active Directory/Entra ID, and HR systems.

Badge event integration with SAP, UKG, ADP, T&A, or ERP systems.

Strong knowledge of OT network segmentation, industrial firewalls, VLANs, and PoE.

Experience with SaaS/hybrid architecture, failover, data synchronization, and recovery.

Physical security cybersecurity hardening including certificates, encryption, patching, and tamper protection.

Knowledge of GDPR, data residency, ISO 27001/27002, and ISO 22340.

Scripting experience with Python and/or PowerShell.

Strong vendor evaluation, RFI/RFP, and POC experience.
