Hardware-in-the-Loop Engineer

Responsibilities

• Manage and scale a growing fleet of HIL rigs on ARM and x86 architectures
• Integrate, test, deploy, and maintain HIL solutions involving third-party hardware for Group 1-3 sUAS platforms and companion computers
• Design, build, and integrate simulators with HIL hardware and flight stack software (ArduPilot, PX4) for autonomous validation use-cases
• Configure, flash, and manage firmware across flight controllers (Pixhawk) and auxiliary hardware for automated testing
• Develop and maintain automation scripts (Python, Bash) for system provisioning, health-checking, and monitoring
• Design custom wiring harnesses or interface boards to bridge flight controllers, sensors, networking equipment, and simulation hosts
• Troubleshoot and resolve complex hardware-software integration issues including timing constraints, MAVLink latency, and serial communication faults
• Collaborate with embedded software and simulation teams to ensure high-fidelity sensor data and flight dynamics translate accurately to hardware

Requirements

• Extensive experience deploying, managing, and maintaining complex hardware systems on ARM and x86 architectures
• Strong proficiency in Linux environments using the command line for configuration, performance tuning, and troubleshooting
• Excellent networking skills including deep understanding of IP networking (TCP/UDP, routing, subnets) and diagnosing network bottlenecks in real-time environments
• Deep, hands-on hardware debugging capabilities using oscilloscopes, logic analyzers, and multimeters
• Solid understanding of standard embedded communication interfaces (UART, I2C, SPI, CAN)
• Experience writing robust automation, testing, and infrastructure scripts in Python or Bash
• Experience building or maintaining CI/CD pipelines that interact directly with hardware test benches
• Strong sense of ownership and ability to work cross-functionally to drive ambiguous hardware/software integration problems to resolution

Nice to Have

• Hands-on experience with Group 1-3 sUAS hardware and flight controllers, particularly Pixhawk
• Familiarity with configuring, debugging, and integrating open-source flight stack software (ArduPilot, PX4)
• Working knowledge of communication protocols used in autonomous vehicles (MAVLink) and robotics middlewares (ROS, ROS 2, DDS)
• Experience developing applications for RTOS such as RT-Linux or NuttX
