What does an electro optical infrared sensor system engineer do?

An Electro Optical Infrared (EOIR) Sensor System Engineer designs, develops, and tests sensor systems that use both visible light (electro-optical) and infrared technology. These engineers work on complex imaging and detection systems used in applications such as surveillance, navigation, and targeting for defense, aerospace, and scientific purposes. They collaborate with multidisciplinary teams to ensure sensor systems meet performance requirements and often participate in integration and troubleshooting activities. Their work involves both hardware and software aspects, including optics, electronics, and signal processing.
