Senior Controls Engineer – OT Networking

This role supports the design, documentation, testing, and sustainment of control systems and OT networking solutions used within large-scale data center technology environments. The engineer will work closely with internal engineering teams as an extension of their organization, contributing to control system design efforts without full autonomous ownership. The role involves developing extensive technical and design documentation, supporting lab-based and on-site testing activities, and providing subject-matter expertise across OT systems. Hands-on work will include interaction with PLCs, SCADA systems, and building management platforms, while testing execution will follow established plans and instructions. The position requires regular presence in Sunnyvale-based labs and periodic travel to data center sites depending on operational needs.
