Join a pioneering force in network automation!
At IP Fabric, we enable people to uncover the truth about their networks. Built by network professionals and industry experts, our innovative solutions are transforming how enterprises manage their networks. As a post-Series B company, we're expanding rapidly across Europe, the U.S., and beyond.
At IP Fabric, we build software that continuously discovers, models, and validates enterprise networks at scale. Our platform gives engineers a single, reliable source of truth about their infrastructure—across vendors, technologies, and environments.
Founded by network engineers and now a fast-growing post-Series B company, IP Fabric operates at the intersection of distributed systems, networking, and data-intensive backend engineering. We’re scaling globally, but we’re deliberate about how we build: with ownership, technical rigor, and long-term thinking.
The ChallengeEnterprise networks are massive, heterogeneous, and constantly changing. Discovering them accurately is a hard distributed systems problem.
Our Network Discovery Platform scans hundreds of thousands of devices, traverses multiple network domains in parallel, collects configuration and state data, and continuously reconciles it into a consistent model. The system must be fast, fault-tolerant, observable, and correct—even when the network isn’t.
We are redesigning this platform with a parallel, horizontally scalable architecture, and we’re looking for a Principal Engineer who wants to shape how this system works at its core.
As a Principal Backend Engineer, you will work on one of the most critical parts of IP Fabric’s product. You’ll design and build backend services that operate deep in the engine room of the platform - where performance, concurrency, and correctness matter more than frameworks.
This is a hands-on engineering role with real architectural influence. You will own problems end-to-end, make design decisions, and see your work running in production on complex customer environments.
You’ll collaborate closely with other backend engineers, network experts, and platform teams - but you’ll also have the autonomy and trust expected from a Principal Engineer.

What We Do
IP Fabric’s Automated Network Assurance Platform helps companies empower their network engineers to discover, verify, and document large scale enterprise networks within minutes. IP Fabric automates network infrastructure data collection and provides predefined verifications that highlight inconsistencies, misconfigurations and issues within enterprise networks.
With experience and strength across Financial Services, Manufacturing, Logistics, Public Sector and more, we are ready to support businesses in addressing their key network management challenges with a new, analytically driven way of managing your network infrastructure.
Using a unique network model and algorithms, the system reconstructs network state and simulates actual packet flows to detect critical violations, business-impacting inefficiencies, and verifies policy compliance.
Based on graph theory of mathematics, native visualization of all network topologies and protocols provides unparalleled visibility, answering the question about how the network is running. Beautiful documentation and report outputs can be used directly as part of an existing process or managerial reporting requirements
