Hardware and Embedded Systems
Engineering the software and electronics inside physical devices
Overview
Hardware and Embedded Systems covers the roles that design physical electronics and write the software that runs directly on them. Every physical device that contains a processor — from medical equipment and industrial machinery to consumer electronics and autonomous vehicles — depends on the work of hardware engineers and embedded software engineers to function correctly and reliably.
The category spans two closely related disciplines. Hardware Engineers design circuits, PCBs, and electronic systems. Embedded Systems Engineers write the firmware that runs on that hardware — often in C or C++, within tight constraints on memory, power, and real-time performance. Robotics Engineers combine both disciplines with AI and control systems to build autonomous physical machines. These roles are among the most technically demanding in technology and are consistently degree-dependent. They reward people who want to work at the physical boundary of computing — where software meets the real world.

Core Themes
- Designing electronic circuits, PCBs, and hardware systems for physical products
- Writing firmware in C and C++ for microcontrollers and embedded processors
- Implementing communication protocols between hardware components and systems
- Optimising code for real-time performance, memory, and power constraints

Typical Entry Points
Most roles require degrees in Electronic Engineering, Computer Engineering, Electrical Engineering, or Computer Science. Hardware Engineering and Robotics are among the most degree-dependent disciplines in tech — the analogue electronics and control theory foundations are difficult to acquire without formal education. Building personal projects on Arduino, STM32, or Raspberry Pi development boards is widely recognised as practical portfolio evidence alongside formal qualifications.
Who This Category Is For
- People who want to work where software meets physical hardware — not just in the cloud or on screens
- Those with an engineering or electronics background considering a deeper technical specialisation
- People who enjoy hands-on debugging with physical lab equipment as much as writing code
- Those comfortable with long development cycles and the higher cost of mistakes in physical systems
- People drawn to autonomous systems, robotics, or IoT as long-term career directions
- Those who prefer deep, narrow specialism over broad generalist software roles
- People who want strong job security in sectors where embedded skills remain scarce
- Those prepared for a role that is more degree-dependent than most technology disciplines
