Embedded Systems

Embedded Engineering focuses on designing and developing software and hardware for embedded systems—special-purpose computers built into devices that perform dedicated tasks. Unlike general-purpose computers, embedded systems are designed to efficiently control, monitor, or interact with hardware in real time.

In short, embedded engineers build the software that powers everyday devices like smartwatches, cars, medical equipment, home appliances, drones, industrial machines, and IoT devices.
