But also: while I didn't post this, that's not uncommon for a founding engineer. They're looking for someone to help start the company from scratch, typically with a healthy dose of equity. It's a calculated risk for the engineer, possibly worth anywhere from zero to a gazillion dollars depending on outcome.
It's not typical for founding engineers. It's plausible for a cofounder, with 30%-50% equity.
I normally wouldn't comment, but expecting someone with that skillset and those kind of opportunities available to them to work for free for 4-6 months with the promise of actual pay "when our seed round closes" was so egregious I couldn't help myself, sorry.
