About Rover

Rover is transforming how professional sports teams connect with their fans. We started by building the best-in-class mobile engagement platform for teams—and now we’re becoming the full-stack marketing engine behind game-day experiences, ticketing, merch, sponsorships, and fan engagement across every channel. We currently work with over 60 professional teams across the NFL, NBA, NHL, and MLS, supporting over 40 million active fans. Our real-time platform ingests 1,000+ fan interaction events per second from our SDK — fueling personalized messaging, automation, insights, and delivering over 2 billion notifications a year, with infrastructure capable of sending 50,000+ notifications per second during peak load.

We’re at a pivotal moment. Generative AI is reshaping how software is built and what’s possible for nimble, specialized companies. At Rover, we’re embracing this fully. We’re retooling every part of our product process to be AI-first—unlocking a 5–10× step change in output while maintaining an obsessive focus on product quality and customer needs.

If you’re excited about building at the edge of what’s possible with AI—while helping some of the world’s most beloved sports franchises deepen their fan connections—you’ll thrive here.

How We Work

• Lean & Fast: A flat org structure, tight feedback loops, and direct access to decision-makers. You’ll report directly to our Head of Product.
• In-Person Collaboration: We work in-person on Mondays and Tuesdays in Toronto to brainstorm, whiteboard, troubleshoot, and eat together. The rest of the week is flexible.
• Iterate Aggressively: There’s no manual for this yet. We experiment relentlessly, double down on what works, and move fast.
