Mission
Finch was started by 2 friends (Nino & Steph 🙇🏾‍♂️🙇🏻‍♀️) who struggled with anxiety and depression and found self-care challenging to stick with. We decided to build Finch hoping to make self-care fun and accessible after seeing many others share similar struggles. Finch was launched in 2021, and our team is grateful to have helped over 20 million people on their mental health journeys.
Finch is profitable and we believe in responsible growth. We are a small but mighty team who are passionate about mental health.
Role Summary
At Finch, we’re reimagining how wellness meets gaming — making self-care not just easy, but irresistibly fun. As our Principal Product Engineer, you’ll blend creativity, product intuition, and technical skill to identify and execute high-impact opportunities that fuel our growth. You won’t just ship features — you’ll run bold experiments, uncover new growth loops, and engineer delightful experiences that stick. If you thrive at the intersection of data, design, and rapid iteration, we’d love to meet you.
