Skills
About the Role
You will own the lifecycle of operational technology systems, from architecture and engineering design through commissioning, operations, refresh, and decommissioning. You will configure industrial control, facility automation, power monitoring, networking, and IT/OT integration systems. You will strengthen OT cybersecurity, manage incidents and changes, define observability and IOC data integrations, lead commissioning deliverables, maintain technical documentation, and improve the reliability, availability, and security of multi-site OT infrastructure.
Requirements
- 7+ years of hands-on OT/controls engineering or OT infrastructure experience.
- Experience owning industrial control systems in operational environments.
- Experience in data center, colocation, energy, utilities, or equivalent 24/7 critical infrastructure environments.
- Hands-on expertise with SCADA, DCS, PLC programming, HMI configuration, and historian platforms.
- Proficiency with Modbus TCP/RTU, DNP3, BACnet/IP, PROFINET, IEC 61850, OPC-UA, and MQTT.
- Understanding of OT networking, industrial Ethernet, managed switches, VLAN segmentation, ring redundancy, and OT/IT boundary architecture.
- Knowledge of IEC 62443 and NIST SP 800-82 and experience implementing security controls in live control-system environments.
- Experience with data center power and cooling systems and BMS/EMS and power-monitoring integration.
- Technical documentation skills, including P&IDs, loop drawings, network diagrams, commissioning reports, and RCA documentation.
- ISA CCST, ISA CAP, or equivalent controls or OT certification.
