Commonwealth Fusion Systems is seeking a versatile OT/IT Support Engineer to join their Milpitas site. This is a hands-on, blended role split between managing shop-floor operational technology (OT) infrastructure and providing direct end-user desktop support. You will serve as the primary on-site technical point of contact, ensuring engineers, technicians, and operations teams have reliable, high-performing workstation technology while maintaining and scaling the physical network and compute infrastructure that powers testing and manufacturing operations.
Key responsibilities include:
- Deploy, monitor, and maintain local site server cabinets, industrial network switches, patch panels, cabling, power equipment (UPSs), and edge compute nodes supporting test rigs and manufacturing lines
- Perform physical installation and basic configuration of networking gear (switches, access points, edge firewalls) in coordination with central Network and IT Security teams
- Provide white-glove hardware and software troubleshooting for local staff, including onboarding, endpoint deployment (Windows, Mac, Linux), workstation peripheral setup, and rapid incident resolution
- Maintain accurate asset tracking, hardware inventory, rack elevations, and lifecycle management for all IT/OT endpoints and spare hardware at the facility
- Ensure conference rooms, display systems, and audio/video equipment are operational and updated
- Partner with manufacturing engineers, control systems teams, and corporate IT to safely integrate operational technology networks with core enterprise systems
- Create clear end-user documentation, standard operating procedures (SOPs), and site network layout diagrams
- Take ownership of the physical site, maintaining high standards for organized cabling, hardware staging, and overall technical workspace presentation
The ideal candidate is a hybrid problem solver who enjoys interacting with users face-to-face while staying deeply connected to core OT/IT infrastructure. You should be a self-starter, strong communicator capable of explaining complex technical topics to both non-technical staff and high-level engineering teams.
REQUIREMENTS:
- 3–5+ years in a hands-on technical support, IT systems administration, or site infrastructure engineer role
- Deep familiarity with supporting and troubleshooting Windows, macOS, and basic Linux (Ubuntu/RedHat) environments; Kubernetes experience is a plus
- Demonstrated hands-on experience racking/stacking servers, patch panel punching, cat6 ethernet cabling, clean cable management, and hardware troubleshooting
- Familiarity with Terraform, Ansible, and using those patterns to scale out repeatable systems
- Strong working knowledge of TCP/IP, VLANs, subnetting, DHCP, DNS, and basic CLI network switch configuration (Cisco, Ubiquiti, Juniper, or similar)
- Experience with Active Directory, Okta, and modern endpoint management tools
- Ability to work 100% on-site in Milpitas, CA
- Ability to lift up to 50 lbs occasionally
- Ability to perform activities such as stooping, climbing, standing, sitting for extended periods
- Willingness to travel or work required nights/weekends/on-call occasionally
- Dedication to safety to mitigate industrial hazards that may include heat, cold, noise, fumes, strong magnets, lead, high voltage, high current, pressure systems, and cryogenics
