We're building a 5G network management web application.
You'll lead the UI and integration for the network electronics module : clear, safe, operator-friendly flows to visualize device status, manage L2/L3 constructs (interfaces, VRF/VPRN, routes, VPLS), configure mirroring (SPAN/ERSPAN), and present PCAP analysis results.
A key UX principle is the split between a right-side contextual panel (fast, read-first, safe actions) and an Administration area (full CRUD, validations, dependency checks).
You'll help us bring this philosophy to production.
Responsibilities Implement the panel views (summary, KPIs, compact L2/L3 listings, mirroring/PCAP lists with "View analysis" ) and link-outs to Administration for full edits.
Build Administration modules with robust tables, forms, and modals for: Interfaces (physical, subinterfaces/VLAN) L3 (VRF/VPRN, static routes, basic BGP neighbors view) L2 (VPLS) Mirroring (SPAN/ERSPAN/PW) PCAP repository/analysis (upload, analyze, filter, download, analysis modal) Define validations and guardrails (e.G., IP overlap detection within a VRF, "port in use" indicators) and dependency warnings before destructive actions.
Collaborate with backend to shape normalized data contracts across vendors and ensure accurate mapping of L2/L3 concepts into the UI.
Deliver thoughtful UX: empty states, tooltips, confirmations, graceful error handling, and loading states.
Must-have (Networking-first) Proven hands-on networking experience building or integrating tools that configure or audit routers/switches in production.
Strong L2/L3 fundamentals: VRF/VPRN, VLAN/subinterfaces, static routing, BGP (and familiarity with OSPF/IS-IS), L2VPN/VPLS (SAP/SDP), SPAN/ERSPAN.
Comfortable with device models and management interfaces (conceptually and/or practically): CLI, SNMP, NETCONF/YANG, RESTCONF/gNMI (any subset is fine if you can reason about integration trade-offs).
Ability to read and reason about PCAPs (Wireshark/tshark) and summarize insights (protocols, talkers, TEIDs, timelines).
You are a developer who can translate networking concepts into clean UI flows and validations (framework can be learned on the job).
Nice to have (Front-end & tooling) React TypeScript / Node.Js experience (tables, dynamic forms, modals, state/error handling).
Experience with design systems (Tailwind or component libraries) and Figma collaboration.
Accessibility good practices (labels, ARIA, keyboard navigation).
Exposure to 5G traffic patterns (GTP-U, PFCP) and typical analysis dashboards.
Example deliverables Right-panel Summary & KPIs with refresh/copy actions and link to Administration.
Right-panel tabs (read-first): Ports, L3, L2 (VPLS), Mirroring & PCAP (show only last 3 PCAPs "View analysis").
Administration modules for: Interfaces (create/edit/delete physical & subinterfaces/VLAN) with IP overlap check and "port in use" signal.
L3 (VRF/VPRN CRUD, static routes CRUD, basic BGP peers view).
L2 (VPLS) CRUD.
Mirroring CRUD (SPAN/ERSPAN/PW).
PCAP repository (upload, analyze, filter, download, analysis modal).
To apply: Share 2–3 relevant case studies demonstrating network configuration/management UI or router/switch integration, your availability, and hourly/daily rate.
