Full job description

Backend Engineer - OT Security Team

  • Engineering
  • Ramat Gan, Israel
  • Senior
  • Full-time

Description Zero Networks aims to protects tens of thousands of OT devices worldwide by managing enterprise switches directly. We're evolving how we integrate with switches - moving toward more modern network management protocols and a wider range of vendors. You'll own that integration layer end-to-end - backend services and the networking know-how behind them.

Responsibilities

  • Design and build the software that talks directly to enterprise network switches: real devices, real production networks, real impact.
  • Push the boundaries of how we manage devices at scale: new protocols, new vendors, better abstractions.
  • Build the cloud backend that turns raw device data into something powerful (Go/C#, gRPC, PostgreSQL).
  • Solve hard, unglamorous distributed-systems problems: concurrency, reliability, scale - with code that ships to production and protects real infrastructure

Requirements

  • 3-5 years as a backend engineer, proficiency in at least one of Go/C#/Java/C++.
  • Networking knowledge: L2/L3, VLANs, routing, TCP/IP, ACLs.
  • Hands-on experience automating network devices - SSH/CLI, NETCONF, RESTCONF, SNMP, gNMI, Netmiko/NAPALM, or similar.
  • Comfort with concurrent code that has to survive flaky real-world network conditions

Nice to Have

  • Multi-vendor network experience (Cisco, Aruba, and others).
  • Cloud experience (GCP/AWS/Azure) and microservices/gRPC.
  • Experience with flow-based telemetry protocols (IPFIX, NetFlow, sFlow).

Tech Stack Go, C#, PostgreSQL, gRPC, GCP, microservices, and standards-based network management protocols.
