  • Familiar debugging complex HW/SW system interactions
  • Comfortable writing clear technical documentation (e.g. test reports)
  • Strong communication skills across engineering and customer teams
  • Active U.S. security clearance

Desired:
  • Experience with hardware-in-the-loop (HIL) and device automation
  • Experience testing embedded systems, networking devices, or mobile
  • Experience with containerization (e.g. Docker, Kubernetes, QEMU)
  • Familiar with network/protocol validation (e.g. Wireshark, Scapy)
  • Experience with RF or wireless systems (e.g. 802.11ac, Zigbee, SDR)
  • Experience testing firmware, drivers, and low-level code/services
  • Exposure to cybersecurity, vulnerability research, or pentest teams
  • Experience with observability, telemetry, or reliability engineering
