The discussion highlights that the titles "embedded system software engineer" and "embedded system programmer" are often used interchangeably, with no significant difference in job roles. The term "engineer" may suggest a deeper understanding of specific technical areas, such as electronics or physics, while "programmer" indicates broader software development skills. However, many companies apply either title to their embedded software developers, regardless of their specific expertise. The conversation also touches on the perception of the title "engineer" in the software field, with some expressing skepticism about its appropriateness for software development roles.
