The real-time software engineer designs and develops real-time embedded software. This has various dimensions.

First, the specification of a program and the preparation of its architecture according to the need expressed by the applicant. He / she then chooses the microcontroller or the microprocessor with which he / she will work according to a certain number of criteria (frequency of operation, available interfaces etc.). More generally, he / she will take into account the constraints of the embedded world (computing power, timings, memory size etc.), which are more restricted than in other areas.

Then, the coding part, during which he / she will implement what has been specified.

Finally, the validation part, which includes different types of tests:

  • Unit tests on a PC, to test the source code.
  • Functional tests with an electronic board where he / she may use an oscilloscope to check timings for example.
  • Integration tests where he / she will check the overall functioning of the system which can include several electronic boards, PC software, …

This profession can be exercised in many application areas – medical, industrial etc. -, in different working environments.
