This role focuses on developing robust test infrastructure, improving product reliability, and enabling continuous validation across hardware and software solutions. Candidates will develop automated validation frameworks, integrate testing into CI/CD pipelines, and support verification activities spanning low-level firmware, networking systems, and mission-driven software capabilities. Work includes functional, integration, regression, and hardware-in-the-loop testing aligned with quality, operational effectiveness, and compliance objectives.

Required:

  • 5+ years experience in software development or test engineering
  • Strong programming experience in Python, C/C++, and/or Rust
  • Experience deploying automated test frameworks (e.g. pytest, Robot)
  • Experience testing embedded or Linux-based systems platforms
  • Hands-on experience integrating testing into CI/CD pipelines
  • 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


Positions available in Arlington, VA.
