What is a part time founding engineer?

A Part Time Founding Engineer is an early team member at a startup who contributes to the technical development of the company while working less than full-time hours. They often help build the initial product, set up engineering practices, and may influence key technical decisions. Despite working part time, they usually receive equity in the company and are considered a core part of the founding team. Their role can be flexible and may evolve as the company grows and hires more staff.
