You will work closely with engineering, cybersecurity, and project teams to install, configure, and validate networking infrastructure at operational energy sites.
Responsibilities
* Deploy and configure OT and enterprise network infrastructure at client energy facilities
* Travel extensively to project sites across the UK, EU, and United States
* Install and configure network equipment including Firewalls, Ruggedized switches, Cellular gateways, Edge compute systems
* Deploy OT monitoring infrastructure including Tenable OT sensors
* Build and configure virtualization environments using Proxmox to host operational VMs
* Perform network configuration across major vendor platforms including Fortinet, Cisco, Palo Alto Networks, Cradlepoint
* Conduct system validation, troubleshooting, and commissioning
* Produce as-built documentation, network diagrams, and configuration records
* Create single-line diagrams and markups using Visio, Lucidchart or Bluebeam
* Work directly with client engineering and operations teams in control rooms and field environments
* Support safe installation practices in industrial and energy facilities
Qualifications
* Experience deploying and supporting enterprise or OT networks
* Strong familiarity with Fortinet, Cisco, Palo Alto, Checkpoint or similar enterprise networking platforms
* Experience installing and configuring industrial or field networking equipment
* Familiarity with Proxmox or other virtualization platforms

What Success Looks Like in This Role
Success in this position is defined by the ability to operate confidently and independently in the field while delivering high-quality, production-ready network deployments. In this role, successful engineers will:
* Arrive on-site prepared, organized, and ready to execute deployments with minimal supervision
* Independently install, configure, and validate network infrastructure in live OT environments
* Troubleshoot and resolve complex issues without relying on constant remote support
* Deliver clean, stable, and secure network deployments that meet client and operational requirements
* Produce accurate and professional as-built documentation and network diagrams

* Represent Centrii professionally in front of clients, partners, and asset operators
* Adapt quickly to changing site conditions, project timelines, and technical challenges
* Maintain a strong focus on safety, quality, and reliability in industrial environments
Top performers in this role are those who take ownership of their deployments, solve problems proactively, and can be trusted to represent the company in the field without oversight.
