    Whistle was born out of our love for pets. As the world’s first technology company dedicated to helping pets live longer and happier lives, we build solutions for common problems faced by pet parents everywhere. Whether a pet is an escape artist, an avid adventurer or a happy couch potato, Whistle provides information and insights to help ensure both pets and their people stay healthy and happy for years to come.

    Our current market-leading products include a cellular-enabled GPS tracker and a WiFi & Bluetooth-enabled activity monitor. We do all design and development in-house, from PCB design to embedded software, data analytics to mobile apps. Our pack thrives on solving hard problems in nimble teams.

    Backed by the largest petcare company in the world, Whistle is positioned for growth as we continue to evolve our product offerings and add to our very dynamic team. If you believe you have what it takes to work in a highly independent, fast-paced environment where teamwork is critical and flexibility is a must, then Whistle might be the place for you.
