Overview

NetBox Labs is seeking a Backend Software Engineer to join our rapidly expanding Observability Product team, which owns the full suite of NetBox Labs observability products—from Assurance and Discovery to upcoming Telemetry and Monitoring capabilities—helping customers gain real-time network visibility, automatically discover and monitor their infrastructure, and keep configuration drift in check.

Role Focus

This role is focused on our open source Observability Agent (including pktvisor and discovery) and has the following requirements.

Responsibilities

• Deep knowledge of the OSI framework, networks and protocols—especially DPI, SNMP, sFlow/NetFlow, gNMI.

• Linux system and network programming experience (e.g., system calls, IPC, processes, threads, sockets).

• Experience with C++ (and/or Rust), as well as Go and Python.

• Experience with eBPF is helpful.

Team Responsibilities

• Work with a full stack team to build and maintain open source, source-available, and closed source software across our observability project portfolio—shipping to the community and delivering into our commercial cloud and on‑premise products.

• Integrate closely with NetBox’s data model to drive workflows for reconciling observed vs intended state and enriching telemetry and monitoring data.

• Define and maintain data schemas and APIs shared across products.

• Ensure observability systems meet scalability and reliability goals (SLAs/SLOs).

• Implement testing, CI/CD automation, and code quality standards across observability services.

General Requirements

• 5+ years of professional experience as a software engineer, and 2+ years in a startup environment.

• Experience in distributed systems and backend microservices development.

• Strong understanding of gRPC, protobuf, event-driven architecture, and streaming data systems.

• Experience with Redis streams, Kafka, MQTT, AMQP or other messaging systems.

• Familiarity with programmatic interaction with network infrastructure via APIs, SSH/CLI automation (e.g., Netmiko, NAPALM), or other network automation frameworks.

• Familiarity with observability concepts (metrics, logs, traces) and related protocols, especially OpenTelemetry.

• Strong communication skills, including the ability to write clear technical specifications with diagrams.

• Familiarity with data visualization and analytics frameworks such as Grafana.

Nice to Have

• Experience building multi-tenant SaaS systems with security and compliance awareness (e.g., SOC 2).

• Familiarity with Mimir, Loki, ClickHouse, Elastic, or other analytical data stores.

• Familiarity with AI/ML approaches for anomaly detection or performance prediction.

• Experience working with or contributing to open source projects, especially in observability.

Culture and Values

• We own and solve problems with high attention to detail.

• Our open source contributors, users, customers & team are all part of our community. When our community wins, we win.

• We prioritize simplicity and think twice before adding complexity.

• Clear communication helps keep our team aligned and collaborating smoothly.
