Philadelphia, PennsylvaniaOpen to RemoteFull Time$120k - $140kA growing manufacturing company is looking to hire an OT Security Architect to join their team. This is with a large enterprise manufacturing organization operating across 13 domestic sites with an active greenfield facility currently under construction. The environment spans both IT and OT, with security coverage across active manufacturing floors. The core stack includes Rockwell Automation platforms, Stratix industrial networking, Palo Alto firewalls, enterprise EDR, and SIEM infrastructure.This team is building, not patching. The greenfield site is a ground-up implementation, and this role owns both the design and the execution.
