Senior Backend Engineer

Small businesses represent 99.9% of all companies, yet they're still forced to choose between clunky, outdated enterprise phone systems or their personal phones. This multi-billion dollar market has been overlooked for decades, left to cobble together solutions that slow them down instead of helping them grow.
Quo is changing that. We bring calls, texts, and customer information together into one easy-to-use, AI-powered platform. We're not just building a phone system. We're setting a new standard for how businesses connect with their customers.
Driven by our values, we move fast, build with determination, and obsess over delivering value to the businesses that have been underserved for far too long.
Today, Quo is trusted by more than 120,000 companies and rated #1 in customer satisfaction on G2. We're backed by Y Combinator, Tiger Global, Craft Ventures, Slow Ventures, and other top-tier investors. It is safe to say we're onto something big.
About The RoleAs a Senior Backend Engineer at Quo, you will spend a majority of your time coding, architecting, and owning moderate to complex components.
