1m+ mobile app developers and marketing teams use OneSignal to send push notifications, in-app messages, and emails. We started as a YCombinator-backed company. Our founders were frustrated with existing push notification tools, so we built our own system. Our customers can design banners, pop-ups, and interstitials without a single line of code. 
When you pick up your smartphone, the first thing you will see are push notifications - maybe there’s a breaking news alert, a football game reminder, a promo from your favorite retailer. Whatever it is, chances are the message you are reading was sent using OneSignal. Now we help businesses send over 8 billion push notifications every single day. 
The company has been growing quickly both in terms of revenue and employees. We have raised a total of $34M from investors including SignalFire, Y Combinator, and Rakuten Ventures. OneSignal customers include Volkswagen, Verizon, Burger King, 7 Eleven, Zynga, Virgin Mobile, KFC, and many more. Join us in scaling the business!

In keeping with our beliefs and goals, no employee or applicant will face discrimination/harassment based on: race, color, ancestry, national origin, religion, age, gender, marital domestic partner status, sexual orientation, gender identity, disability status, or veteran status. Above and beyond discrimination/harassment based on 'protected categories,' we also strive to prevent other, subtler forms of inappropriate behavior (e.g., stereotyping) from ever gaining a foothold in our office. Whether blatant or hidden, barriers to success have no place at OneSignal.
