 Job Description

Slice are on the hunt for a Senior Engineer to develop internal and customer facing web applications with Ruby on Rails while helping us grow our product offering by making great engineering decisions!

What is Slice?

Slice is the leading technology and marketing platform made exclusively for local pizzerias, making it super easy to order delicious, authentic local pizza anywhere, anytime. We serve the $45 billion U.S. pizzeria market in two ways: by providing a pizza-centric mobile and web ordering experience for consumers, and by empowering local restaurants with the technology, tools, and marketing to grow their business, while helping them compete with Big Pizza.

Slice was born in 2011 and has quietly bootstrapped its way to building a network of more than 8,000 pizzerias nationwide. Ilir Sela, our founder and CEO, started the company as a passion project to help his friends and family in the pizza business, but he quickly saw a massive opportunity to champion these small businesses by bringing their bites to the masses. Ilir has since built an amazing team of operators, marketers, technologists, and investors — all dedicated to making it easier for people to enjoy their favorite local pizza.
