Senior Front-End Engineer

Working at

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.  Slice was born in 2009 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 favourite local pizza. We celebrate pizza as the ultimate shareable food: It turns everyday moments into memories and brings together friends, families, and communities. And when you order pizza from a place in your neighborhood, you support a local business. So whether you call it a pizza parlor, slice joint, or pizzeria, we’re here to help you order authentic local pizza and live your best slice life. Local pizzerias are the cornerstone of communities across the country. They handcraft the one food that unites us all: pizza. It fuels our celebrations, family dinners, and busiest days. While pizza lovers crave their favorite local pie, they also crave convenience. This has led people to sacrifice the quality, authentic food of mom-and-pop shops for quick and easy chain pizza. But we believe nobody needs to make that sacrifice. You can have your pie and eat it too. Slice is uniting and empowering local pizzerias with tech, data, and marketing to take charge of their industry, to bring their business into the digital world, and to provide handcrafted, quality pizza with the utmost convenience. Unlike other online ordering services that drive down a pizzeria’s quality and value by charging high order fees, Slice builds a true partnership for a fair cost. We treat our pizzerias like family — with full support, transparency, and championship. This allows shops to expand their business while focusing only on creating the best food imaginable. Better pizza for pizza lovers, bigger profits for pizzerias, and a better experience for all. We believe pizza isn’t just food. It’s a slice of community, a slice of culture, a slice of life.
