Network Engineer, Operations & Reliability at Fluidstack

Fluidstack is seeking a Network Operations Engineer to serve as a Regional Site Lead for one of our datacenter campuses. This is a hybrid role that combines hands on Tier 2/3 network operations with site leadership responsibilities. You'll be the boots on the ground expert for your assigned datacenter/campus, ensuring network reliability through incident response, break fix coordination, and operational excellence. You'll work remotely when workload allows but be onsite as needed for deployments, complex troubleshooting, and critical incidents.

This role is ideal for experienced network operators who want ownership of a datacenter campus while being part of a broader operations organization. You'll partner closely with the Operations & Reliability pillar lead, centralized NOC for Tier 1 escalations, and cross functional teams including Deployment, Hardware, and DC Operations. Success means maintaining high availability for your region, building strong relationships with onsite teams, and growing into regional operations leadership as the team scales.

• Regional Operations Ownership: Serve as the primary network operations contact for your assigned datacenter campus. Own network health, respond to incidents escalated from NOC, and ensure fabrics run reliably. Build deep knowledge of your region's network topology, common failure modes, and operational characteristics.

• Tier 2+ Incident Response: Handle network incidents escalated from Tier 1 NOC during your coverage window. Troubleshoot complex issues across physical and logical layers, coordinate with other engineers for follow the sun coverage, and drive incidents to resolution. Lead incident response when you're the subject matter expert on the ground.

• Break Fix Coordination: Coordinate hardware break fix activities with onsite DC Operations technicians. Manage linecard swaps, optic replacements, device troubleshooting, and RMA processes. Ensure physical infrastructure issues are resolved quickly and don't impact production workloads.

• Deployment Support: Provide operational support during new datacenter deployments and expansions in your region. Partner with Deployment teams on turn up activities, validate production readiness, and ensure smooth handovers from deployment to operations. Be the person who ensures new pods integrate seamlessly into operational workflows.

• Runbook Execution & Improvement: Execute operational runbooks for common failure scenarios and maintenance procedures. Identify gaps in runbooks, document lessons learned, and provide feedback to the Operations pillar lead on runbook improvements. Build the operational knowledge base for your region.

• Cross Team Collaboration: Build strong relationships with onsite DC Operations teams, structured cabling vendors, and hardware logistics partners. Serve as the network engineering liaison for your datacenter campus. Communicate clearly about network status, planned maintenance, and operational issues.

• Regional Mentorship: As the regional team scales, mentor junior operations engineers assigned to your datacenter. Share operational knowledge, provide guidance during incidents, and help build regional operations capacity.

• Strong Operations Background: 5-8 years in network engineering with significant hands on operational experience. You've run production networks, responded to incidents at all hours, and debugged complex failures under pressure. You understand the difference between "working" and "production ready."

• Datacenter Fabric Expertise: Deep experience operating modern datacenter networks including EVPN/VXLAN, BGP, CLOS topologies, and high radix switching. You're comfortable troubleshooting Layer 2/3 issues, BGP routing problems, fabric misconfigurations, and physical layer failures.

• Incident Response Excellence: Proven ability to lead incident response, perform systematic troubleshooting, and drive issues to resolution. You remain calm during outages, communicate clearly with stakeholders, and know when to elevate versus dig deeper. You've been the person others call when things break.

• Site Leadership Capability: You've been the go to network person for a site, datacenter, or region before. You understand how to build relationships with onsite teams, coordinate physical infrastructure work, and represent network engineering in a field environment. You know how to get things done in operational settings.

• Operational Pragmatism: You balance perfection with progress. You can troubleshoot with imperfect information, make pragmatic decisions under time pressure, and prioritize based on business impact. You document as you go and continuously improve operational processes.

• Hybrid Work Comfort: You're productive working remotely but understand that datacenter operations sometimes require hands on presence. You're comfortable with flexible schedules that adapt to operational needs-sometimes remote, sometimes onsite for days or weeks during critical periods.

• AI/HPC Fabric Operations: Experience operating AI/ML or HPC fabrics with RDMA (RoCEv2), lossless Ethernet (PFC, ECN), or high performance networking. You understand the operational precision required when network performance directly impacts workload completion.

• Regional/Campus Operations Leadership: You've been a site lead, campus engineer, or regional operations lead before. You know how to coordinate across teams in a specific geographic location while reporting into a centralized organization.

• Hardware Break Fix Experience: Hands on experience coordinating hardware repairs, RMAs, and physical infrastructure work. You understand datacenter logistics, vendor escalation processes, and how to work effectively with onsite technicians.

• Observability & Monitoring: Familiarity with network monitoring platforms, alerting systems, and telemetry collection. You've used monitoring tools to diagnose issues proactively and tune alerting to reduce noise.

• Automation Exposure: Basic scripting or automation experience (Python, Ansible) for operational tasks. You may not be writing complex automation but you understand how to leverage tools to improve operational efficiency.

• Follow the Sun Experience: Experience working in distributed operations teams with follow the sun coverage models. You understand how to hand off incidents cleanly, communicate operational status across time zones, and coordinate with global teams.

• 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 $150,000 - $250,000 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.
