Senior Backend Software Engineer

Who We Are

In the past, to be a successful restaurateur, you simply had to have a passion for food and a passion for people - but to succeed as a digital restaurateur you also need to have a passion for technology. We believe in the joy of serving others, and that's why we created Otter – to help restaurateurs succeed in online food delivery. Restaurants around the world, both large and small, including Chick-fil-A, Ben Jerry’s, KFC, and Eataly trust our software to power their delivery business.

We increase sales, reduce order issues, and decrease delivery headaches.
