I disagree here, being the founding engineer of a unicorn is quite a different experience than being a core contributor to a mid-size startup.
If you’re talking to someone in the startup sphere, the talk of being a founding engineer in a unicorn is excellent! If that’s not the audience you intend to reach, then it’s akin to an automotive designer discussing about how much downforce they generated through a modest angular adjustment to a spoiler design’s leading edge, while in the midst of casual conversation - lost in translation to anyone outside their field.
