Embedded Systems Engineer
Programs the tiny computers inside everyday devices — cars, appliances, medical devices.
Did you know?
A modern car can have up to about 150 tiny embedded computers, called ECUs, controlling everything from brakes to seat warmers.
How subjects help
- Computer Science: Write tiny, efficient programs that run a washing machine or a car's brakes.
- Physics: Read sensors that measure temperature, speed or pressure and turn them into signals.
- Mathematics: Convert sensor readings into real units and filter out noisy jumps in the data.
A famous name
Margaret Hamilton: Led the team that wrote the Apollo guidance computer's onboard software for the 1969 Moon landing.
Try it yourself: Program a paper traffic light
- Write the order a UK traffic light shows its lights: red, red and amber together, green, amber, then back to red.
- Give each step a time in seconds. Which step should be shortest, and why?
- Add a rule: when someone presses the crossing button, what should change, and when?
- Ask someone to "be" the light and follow your rules exactly. Did anything confusing or unsafe happen? Fix that rule.
Embedded systems and control engineers write the rules that tiny computers inside machines follow, then test what happens in every situation.
