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.

What you’ll do

At Otter POS, we build the backend that keeps restaurant point-of-sale running: orders, payments, menus, and device state across Android tablets in the kitchen and at the counter. Those services have to stay consistent when WiFi drops mid-service.

As a backend engineer on this team, you will design and scale the services behind order orchestration, payment flows, offline-first sync, and multi-device coordination. We want product-minded or systems-focused backend engineers. You do not need prior POS experience.

If you like distributed systems, careful API design, and reliability work under real restaurant conditions, you will fit here.
