# Principal Engineer - Android

Our Story: At COSMO, we inspire kids through innovative technology and a supportive community. Our family-centric products, such as the award-winning JrTrack Kids Smartwatch, enhance children's independence and confidence. This all-in-one device functions as a phone, GPS tracker, and music player, managed via the Mission Control Parent App, which allows parents to set safety alerts and manage contacts. Recognized as a top kids' wearable by PCMag and others, Cosmo is on the rise. About the Role Department: Engineering Role Summary: We are looking for a Principal Engineer to set the technical direction for our Android platform and raise the engineering bar across the organization. As the most senior individual contributor on the team, you will own the hardest architectural problems, define the standards other engineers build to, and drive multi-quarter technical strategy that spans teams and products. This is a deeply hands-on role with org-wide influence: you will still write and review code and lead execution, but your largest impact comes from your technical judgment, your depth in one or more critical domains, and your ability to grow the engineers and processes around you.
