Senior full stack engineer

Company details

Description of the offer

Purpose is building the world’s first AI-powered personal growth coach that helps people go from “I’m doing fine” to “I know who I am, what I care about, and how to live with clarity.”

Founded by Mark Manson (20M+ readers of The Subtle Art of Not Giving a F***) and Raj Singh (100M+ users on last AI product, acquired by Revinate), Purpose is built for people chasing meaning in a noisy world.

We’re launching in a few months to Mark’s massive audience. The product blends personalized AI coaching, habit-building, and emotional intelligence assessments in a way that feels more like a meaningful conversation than an app.

Quick Apply — Answer Both
1. Single-Graph Truth – What is the one unexpected metric or dashboard graph you’d pin to a big screen for our launch week, and why?
2. Shipping Under Uncertainty – Tell us about a feature you shipped knowing it was only 80 % right. How did you protect users, validate quickly, and iterate it to success?

We read every response personally.

This is the moment to join. The fire’s lit, the fuse is short, and we’re about to launch something that actually matters.

Let’s go.
