When you pick up your smartphone, the first thing you’ll see is your push notifications - maybe there’s a breaking news alert, an HQ Trivia game reminder, a message from a dating site, or football scores… Whatever it is, chances are it came from us.

550K+ developers and marketing teams use OneSignal to compose push notifications, automate delivery, and track performance. The company started as a Y Combinator-backed game developer. Our founders were frustrated with existing push notification tools, so we built our own system. It took off like wildfire. Now we send over 4.5 Billion push notifications every single day. OneSignal is the fastest, most reliable customer engagement platform, with the ability to send 850,000+ push notifications per second.

The company is growing quickly both in terms of revenue and employees. It’s a great time to join because we’re still early - we’ve raised a total of $9.5M from investors including SignalFire and Rakuten Ventures (Techcrunch). And despite our early stage, we have massive market penetration (Source: BuiltWith).

Push notifications are only the beginning… We’re on track to power the world’s messages across every channel. Will you help us get there? We’re hiring!
