About The Position

Fluidstack is hiring a Software Engineer, Networking, to build and operate automation and tooling for its growing datacenter network fleet.

The engineer will help ensure network faults can be diagnosed systematically and repaired through repeatable pipelines rather than manual procedures, while supporting reliability and scalability across multiple hyperscale sites.

Requirements

Experience shipping production network tooling or automation that other teams depend on.
Comfort working in any programming language and using AI coding tools.
Experience developing automation tools in Go and Python.
Experience with link diagnostics and optical networks.
Understanding of network monitoring technologies, including gNMI, gRPC, NETCONF, and SONiC.
Fluency with AI tooling, including LLM APIs, MCP servers, and agentic frameworks; regular use of Claude Code, Cursor, or similar tools.
Ability to diagnose network faults systematically, understand how different fault types propagate, and build tools to distinguish them.
Ability to work through ambiguity and quickly become competent in unfamiliar domains.
Willingness to carry a pager, lead incidents, write postmortems, and fix systemic causes.

Experience with RMA and repair lifecycle automation.
Experience with large-scale datacenter fabrics, including BGP, ECMP, and spine-leaf architectures.
Experience with out-of-band network management.

Responsibilities

Define real-time network monitoring requirements, build the alerting lifecycle, and deliver dashboards that show network state across sites.
Build active debugging tools, including linked diagnostics, fleet-wide remote command execution, and repair visualization.
Automate the network repair lifecycle from failure detection through parts management and return to service, including ticket integration and transceiver and optics tracking.
Build network qualification and validation frameworks for new sites and hardware before they enter production.
Own the end-to-end reliability, scalability, and operation of the network at scale through automation, tooling, and incident discipline.
Run network incidents, write postmortems, and address systemic causes.
