At Fluidstack, we’re building the infrastructure for abundant intelligence. We partner with top AI labs, governments, and enterprises - including Mistral, Poolside, Black Forest Labs, Meta, and more - to unlock compute at the speed of light.
We’re working with urgency to make AGI a reality. As such, our team is highly motivated and committed to delivering world-class infrastructure. We treat our customers’ outcomes as our own, taking pride in the systems we build and the trust we earn. If you’re motivated by purpose, obsessed with excellence, and ready to work very hard to accelerate the future of intelligence, join us in building what's next.
We are seeking a Data Center Operations Technician to serve as the on-site specialist for network and structured cabling issues across our AI datacenter infrastructure. You will be the Tier 3 escalation point for network and ICT-related incidents, responsible for troubleshooting physical layer faults, validating repairs, and ensuring rapid resolution of issues that impact customer workloads.
This role sits within the Data Center Operations organization and is assigned to a specific site. You will work closely as an escalation path for Tier 1 and 2 technicians as well as closely with Network Operations, and cross-functional teams to maintain the reliability and performance of high-density AI Infrastructure. When issues exceed on-site scope, you will escalate with clear documentation to Network Operations for deeper investigation.
The ideal candidate bridges two worlds: a strong foundation in structured cabling and fiber infrastructure, combined with enough network fundamentals to interpret device-level diagnostics and validate that physical repairs restore connectivity. You are comfortable being the sole network/ICT escalation resource on-site and take ownership of issues through resolution.
Serve as the Tier 2 escalation point for network and cable plant incidents reported by customers or detected through monitoring
Troubleshoot, diagnose and resolve physical layer issues including fiber faults, transceiver failures, patch panel problems, and cable plant defects. Lead your local team beyond troubleshooting maturing to process and metrics operations as we build automated diagnostics and repair.
Perform fiber inspection, cleaning, testing, and light-level validation to identify and remediate connectivity issues
Participate in the testing and deployment of automated diagnostic and repair tools, serving as a liaison to Network Operations, NRE, and Network Automation teams. Lead onsite pilots, provide constructive feedback, monitor and enforce adoption of tooling systems.
Execute structured cabling repairs including re-patching failed runs and coordinating with Infrastructure Deployment for complex remediation
Run post-repair validation tools to confirm device connectivity, LLDP neighbor relationships, and acceptable optical power levels
Interpret basic network diagnostics — including light levels, interface status, and neighbor discovery — to validate that physical repairs have restored expected connectivity
Document incidents thoroughly and escalate to Network Operations with clear problem statements when issues require logical-layer or deeper investigation
Maintain awareness of site topology and cable plant documentation to accelerate fault isolation
Collaborate with other Tier 2 teams in other regions, developing best practices
Build and manage dashboards and views in ticketing systems, providing insights and guidance on workload.
Collaborate with Tier 1 technicians and provide guidance on network/ICT triage to reduce unnecessary escalations
3+ years of hands-on experience in datacenter environments with a focus on structured cabling, fiber infrastructure, or network hardware support
Proficiency with fiber troubleshooting tools: Visual Fault Locators (VFL), optical power meters, light sources, and fiber inspection scopes
Understanding of fiber types (single-mode, multi-mode), connector standards, and acceptable light-level thresholds for datacenter optics
Familiarity with structured cabling standards and best practices for fault identification and remediation
Ability to interpret basic network interface diagnostics — including link status, optical power readings, and LLDP/neighbor information — without requiring deep protocol-level troubleshooting
Strong documentation and communication skills; able to write clear escalation summaries for remote engineering teams
Willingness to relocate to an assigned datacenter site
Experience with OTDR (Optical Time-Domain Reflectometer) for fiber fault localization
BICSI Installer 1 or Installer 2 certification
CCNA or equivalent foundational network certification
Experience supporting high-density compute environments (GPU clusters, HPC, AI/ML infrastructure)
Familiarity with DCIM platforms and cable plant documentation systems
Prior experience in a tiered support model with clear escalation workflows
Exposure to high-speed optics (100G, 400G, 800G) and associated transceiver technologies
Experience with SQL and JQL building dashboards for operations management and visibility.
Experience with Arista, Juniper, Sonic, Cisco CLI and operating systems
Competitive total compensation package (salary + equity).
Retirement or pension plan, in line with local norms.
Health, dental, and vision insurance.
Generous PTO policy, in line with local norms.
The base salary range for this position is $100,000 - $150,000 per year, depending on experience, skills, qualifications, and location. This range represents our good faith estimate of the compensation for this role at the time of posting. Total compensation may also include equity in the form of stock options.
We are committed to pay equity and transparency.
