Fluidstack is building the infrastructure for abundant intelligence and seeks a Network Engineer to join their Deployment & Integration team. The role focuses on building and validating AI datacenter network infrastructure at scale, including configuring switches and ensuring production-ready handovers to operations.
Responsibilities:
- Deploy and validate datacenter network infrastructure including front-end fabric, back-end fabric, BMS, and management networks
- Configure switches, install and validate optics, coordinate fiber/cabling work, and drive deployments through completion
- Own the hands-on work that turns designs into production networks
- Ensure physical connectivity meets production standards
- Coordinate with structured cabling teams on fiber remediation, validate insertion loss and OTDR traces, troubleshoot optical layer issues, and document physical infrastructure as-builts
- Manage hardware logistics including device staging, rack/stack coordination, RMA processes, and DCIM updates
- Track hardware inventory, coordinate vendor shipments, and ensure devices are ready when deployments need them
- Partner with DC Operations (rack/stack, power, cabling), ICT teams (fiber validation), Hardware teams (logistics), and Network Engineering (config validation) to drive deployments forward
- Maintain accurate documentation of deployment activities including cutsheets, as-builts, validation results, and lessons learned
- Identify gaps in deployment procedures and propose improvements
- Contribute to the deployment playbook that enables the team to scale
- Provide backup operational support during and after deployments
- Respond to incidents, execute troubleshooting procedures, and coordinate break-fix activities
- Build the operational knowledge that makes you effective beyond just deployment execution
Requirements:
- 3-7 years in network engineering with hands-on datacenter experience
- Understanding of modern datacenter fabrics (EVPN/VXLAN, BGP, CLOS architectures)
- Configured production network infrastructure
- Comfortable with CLI, configuration management, and network validation procedures
- Thrives in field environments and enjoys the satisfaction of building physical infrastructure
- Comfortable pulling cable, configuring switches, and troubleshooting optical layer issues
- Methodical approach to diagnosing network issues across physical and logical layers
- Ability to read OTDR traces, validate insertion loss, debug BGP sessions, and trace connectivity through complex topologies
- Clear communicator who can work effectively across technical and non-technical teams
- Experience coordinating work with datacenter operators, vendors, and internal teams
- Ability to document work clearly and follow through on commitments
- Learns quickly from structured guidance and can apply that knowledge independently
- Asks good questions, seeks out documentation, and takes ownership of ramping up on new technologies
- Comfortable with 70-80% travel to onsite deployments (weeks to months) at datacenter locations
- Exposure to AI/ML networking environments with RDMA (RoCEv2), lossless Ethernet (PFC, ECN), or high-performance compute fabrics
- Hands-on experience with Arista, Juniper, or NVIDIA networking platforms
- Strong understanding of structured cabling standards, fiber optics (SMF/MMF), insertion loss budgets, and optical validation tools
- Experience working with structured cabling vendors and ICT teams
- Basic familiarity with network automation concepts, configuration templating, or scripting (Python, Ansible)
- Experience with datacenter infrastructure management tools, asset tracking systems, or inventory management
