Nice to Have * Build type-safe integration with backend services using generated API clients from Protocol Buffers and OpenAPI, shared schemas, and consistent error and auth handling. * Micro-Frontend Architecture with hands-on experience implementing Module Federation (ideally Module Federation 2.0 with Vite). * Experience working with data visualization (Recharts, D3, Grafana etc). * Strong understanding of authentication and authorization patterns (Auth0/OAuth, RBAC) in single-page applications. * Experience working in product teams (e.g. in a SaaS environment). * Experience with Terraform or infrastructure-as-code tooling. * Contributions to open-source projects or developer tooling. * Experience with performance optimization and Lighthouse CI budgets. * Familiarity with network infrastructure concepts (IP addressing, device management, SNMP/network discovery). Ways of working * Good communication skills and a proven ability to work collaboratively in small, cross-functional teams. * Comfortable working in a fast-moving environment and contributing to product, design, and technical decisions. * Collaborate with product managers, designers, customer-facing teams, and other engineering teams so features solve real network operator problems. * Review code, mentor teammates, and share best practices for frontend engineering and data visualization. * Participate in planning and help shape the roadmap. ## Description NetBox Labs builds the next generation of network automation tools for modern infrastructure teams, with NetBox as the network source of truth at the center. The Observability team builds the products that connect that source of truth to what is actually running on the network: * NetBox Discovery finds devices, interfaces, and other network entities. * NetBox Assurance brings discovered data into NetBox and helps operators spot drift between intended and actual state, review changes, and decide what to accept. * Fleet Management and the Orb agent deploy, configure, and manage the agents that collect discovery and telemetry data from customer networks. * Diode is the ingestion pipeline that moves that data into NetBox reliably. All of that data has to land somewhere operators can see it, understand it, and act on it in seconds. That is where you come in., * High-frequency telemetry dashboards where customers monitor network and device health live, with streaming time-series charts, heatmaps, and status views. * Drill-down experiences that take an operator from the whole fleet to a single device to a single interface in a few clicks. * Review and management interfaces for discovered data, drift between intended and actual state, and the agent fleet. * AI-powered features and workflows, both in the product and in how the team builds it. You'll work closely with product, design, and the backend engineers who own the query and streaming APIs your dashboards depend on. This role is hands-on: you'll ship features, push rendering performance hard, and set the frontend architecture and practices that let our dashboards scale to large, complex customer networks.
