Responsibilities

Protocol & Feature Validation

  • Manually validate core L2/L3 switching features: VLANs, STP/RSTP, LACP/port-channels, LLDP, IGMP/MLD snooping, QoS, ACLs, static/dynamic routing
  • Validate PoE behavior (PoE/PoE+/PoE++) across port classes, power budgets, and mixed-load scenarios
  • Test switch management interfaces — CLI, SSH, SNMP, REST API, and UniFi Network application/controller integration
  • Perform interoperability testing across multi-vendor topologies and mixed firmware versions
  • Validate clustering, redundancy, and failover behavior under various failure conditions

Firmware & System Testing

  • Perform long-duration soak/stability testing to catch memory leaks, port flaps, and firmware degradation over time
  • Test system behavior under scale conditions (high MAC/ARP table size, VLAN scale, heavy traffic load)
  • Validate authentication, authorization, and access control (802.1X, RADIUS, management access)

Debugging & Root Cause Analysis

  • Debug using switch logs, CLI diagnostics, packet captures, and port/interface statistics
  • Distinguish true firmware/protocol regressions from environment or test setup issues
  • Reproduce field-reported issues and validate that fixes fully resolve reported behavior

Collaboration & Process Improvement

  • Partner cross-functionally with firmware engineers and PMs to shape quality bars and go/no-go release decisions
  • Document bugs clearly with reproducible steps, supporting logs, and impact assessment
  • Continuously improve test plans, protocol coverage, and QA processes with AI-assisted workflows

Qualifications

Protocol & Networking Knowledge

  • Deep, hands-on understanding of L2/L3 protocols: VLANs, STP/RSTP, LACP, LLDP, IGMP/MLD, QoS, ACLs, static/dynamic routing
  • Solid grasp of PoE standards and power negotiation behavior
  • Strong understanding of TCP/IP fundamentals: DHCP, DNS, NAT, VPN

Process & Mindset

  • Solid grasp of software testing methodologies, issue reporting, and test case management
  • Strong ownership mindset — able to independently build out test coverage for new features from spec
  • Organized and detail-oriented, with the ability to manage multiple testing tasks in parallel
  • Passion for quality, networking, and continuous learning in a fast-evolving environment
  • Comfortable using AI to speed up log/capture analysis and the ability to critically evaluate AI-generated output for accuracy before applying it to test work

Preferred

  • CCNA or equivalent networking certification
  • RTOS-based switch testing experience
  • Familiarity with traffic generation tools (iPerf, Ixia, Spirent, or similar)
  • Familiarity with Datacenter testing
  • Hands-on experience testing ProAV-over-IP technologies such as Dante, ST 2110, NDI, or SDVoE
  • Contributions to internal test frameworks, tooling, or test documentation improvements

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
