Role Overview:

CHAOSis seeking askilled Hardware-in-the-Loop (HIL) Engineer to join our hardware engineering this role you will design build andmaintainHIL simulation environments that enable full system integration testing of our Effector platforms bridging the gap between software development and flight hardware. You will work closely with GNC software and systems engineers to ensure our vehicles are thoroughlyvalidatedbefore ever leaving the ground.

The ideal candidate hashands-on experience building and operating HIL or SIL simulation environments for embedded or autonomous systems.

This is a full-time on-siteposition inHawthorne CA.

Responsibilities:

• Design and develop HIL test benches for full effector system integration including flight controllers ESCs sensors and ground control systems

• Integrate high-fidelity simulation models (flight dynamics actuator and sensor models) that accurately replicate real-world behavior

• Integrate hardware components - including autopilot boards communication links power systems and peripherals - into HIL systems

• Develop automated test suites and regression frameworks tovalidatesoftware and firmware changes against HIL environments

• Collaborate with software and integration/test engineers to define test plans and acceptance criteria for new features and hardware releases

• Debug complex hardware-software interactions by analyzing HIL test data logs and telemetry

• Maintain and improve test infrastructure including simulation software real-time targets and data acquisition systems

• Document test methodologies procedures and results clearly for cross-functional team use

• Support transition of HIL-validated systems to integration and flight test phases

MinimumRequirements:

• Bachelors degree inEngineering Computer Science or a related field.

• 3years of experience in hardware-in-the-loop testing embedded systems integration or a closely related discipline

• Hands-on experience building and operating HIL or SIL simulation environments for embedded or autonomous systems

• Proficiencyin real-time simulation platforms ( NIVeriStand or similar)

• Strong programming skills in Python and/or C/C for test automation and system scripting

• Familiarity with flight controller software such as PX4ArduPilot or equivalent

• Experience with communicationprotocols common in drone systems (MAVLink CAN UART SPI I2C)

• Solid understanding ofeffectorsystem architecture including propulsion navigation and control loops

• Experience with version control systemsand CI/CD pipelines for automated testing

• Strong analytical and troubleshooting skills across hardware and software domains

• Ability to obtain andmaintaina U.S. security clearance

Preferred Requirements:

• Masters degree inEngineering

• Experience with ROS or ROS 2 for simulation and integration testing

• Familiarity with MATLAB/Simulink for flight dynamics or control system modeling

• Exposure to flight test operations and transitioning systems from HIL to field testing

• Experience with FPGA firmware development or embedded Linux environments

• Knowledge of RF systems GPS signal simulation or sensor fusion techniques

• FAA Part 107 certification or equivalent UAV operational credentials
