Senior Backend Engineer
Confirmed on the employer's own hiring board on Oct 10, 2026. First seen by Alion on May 23, 2025.
Small businesses represent 99.9% of all companies, yet they're still forced to choose between clunky, outdated enterprise phone systems or their personal phones.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’s safe to say we’re onto something big.
About the Role
As a Senior Backend Engineer at Quo, you will spend a majority of your time coding, architecting, and owning moderate to complex components. Beyond your technical work, you may also lead a small team or a project. You might also spend time providing technical guidance, code reviews, and design and delivering on small/medium size projects end-to-end.
Potential areas of focus include:
- Leveraging AI and advanced technologies to help customers manage and derive insights from their data, optimizing the customer onboarding experience.
- Empowering users to independently set up, manage, and scale their accounts with a seamless and compliant process.
- Enhancing core messaging and calling features, improving customer data management, and optimizing the visibility of conversations and contacts.
In any of these areas, you’ll have the opportunity to tackle impactful challenges and help build scalable backend systems that will support a growing user base.
Technical stack and tools:

- You are intentional about how your work impacts customers, the community, and each other. You practice empathy, generosity, and thoughtfulness as you evaluate tradeoffs in pursuit of the best solution.
- You are curious. You better seek to understand the ‘why’ behind things, so that you can better plan and build the ‘how’. You support your teammates and customers through the continuous pursuit of knowledge. You’re a lifelong learner.
