## Job 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.

**Live in Zeronetworks’s hiring system.** Read from the company's own applicant tracking system, not reposted from a job board — so it's a real, open requisition rather than an ad that outlived the role.

We remove it as soon as it disappears at source.
