Small businesses represent 99.9% of all companies, yet they're still forced to choose between clunky, outdated enterprise phone systems or their personal phones.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. 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. Today, Quo is trusted by more than 120,000 companies and rated #1 in customer satisfaction on G2.

About The Role Our Foundations team sits between the cloud infrastructure and the product teams who build features. We build the patterns, libraries and backend capabilities the rest of Quo engineering builds on. When a change touches every team, it usually starts here.

Foundations is doing the first big pieces of the migration and creating the patterns and tools so every other team can finish their part on their own. As a Staff Backend Engineer, you'll be hands-on and writing production code, working closely with the Foundations lead. You'll stay on one team but spend a lot of your time alongside other teams, helping them adopt a new pattern, writing code with them and making sure it works for their part of the product.

This isn't a feature team role, and it isn't DevOps or SRE either. It's backend engineering whose impact shows up across the whole of Quo. Lead the technical work on our REST to GraphQL migration, building the core pieces yourself and the patterns that let every other team finish theirs.

Help rework authentication and authorization across Quo, working directly with each team it touches and writing code alongside them. Build reusable libraries and backend patterns that product engineers use every day as they ship features. Set technical direction for foundational work, from search to API design, and bring other teams along through design docs, reviews and pairing.





Mentor engineers on Foundations and across the org, raising the bar for how backend work gets done at Quo. Node and TypeScript on the backend Kubernetes on AWS Web (React), iOS and Android clients on the other side of the API Language is not a filter. If you've built the right things in Go, Python, Java or anything else, we'd rather talk to you than to someone who knows Node but hasn't.

You write TypeScript every day and know it deeply. You've built and run GraphQL APIs in production, and ideally you've helped move a codebase from REST to GraphQL or led a similar API modernisation. You're a strong backend engineer with a solid grasp of systems design, reliability and infrastructure, and you've built systems that scale.

You enjoy building things other engineers depend on, like shared libraries, patterns and platform capabilities, and you care about making them easy to use. You can influence technical direction across teams, explain trade-offs clearly and get people on board without needing authority over them. You've worked somewhere with real users and real structure, whether that's a larger tech company or a scaling startup, and you want to make a visible difference here.

You're happiest writing code. This is a hands-on role, not a DevOps, SRE or developer productivity programme role.
