As others have said, this is for a hired engineer role, not a CTO. Maybe they hope to grow you into that role, maybe not - those skills are very different than being a builder! CTO or first engineering hire should be 1-8% depending on your contributions and when you join. Honestly, I wouldn't bother with the equity. They want you to write code - think of it like a job - you are not a co-founder.
