Role Overview:
CHAOS is seeking a skilled Control Systems Engineer to join our hardware engineering team. In this role, you will design, build, and maintain HIL 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 thoroughly validated before ever leaving the ground.
The ideal candidate has hands-on experience building and operating HIL or SIL simulation environments for embedded or autonomous systems.
This is a full-time, on-site position in El Segundo, 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 to validate software 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
Minimum Requirements:
Bachelor's degree in Engineering, Computer Science, or a related field.
