Senior Backend Engineer

$172k - $202k per year

Quo

Small businesses represent 99.9% of all companies, yet they're still forced to choose between clunky, outdated enterprise phone systems or their personal phones.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.

Technical Stack And Tools

  • Our backend is built on Node using Typescript.
  • We use Kubernetes on AWS to orchestrate our infrastructure setup and deployment.
  • The overall architecture is event-driven microservices with Temporal and RabbitMQ at the center of it.
  • We use a variety of databases for different purposes: Postgres, Mongo, Elastic, and Redis.
  • Observability Tools: Datadog
  • Other Tools: Figma, Linear, Notion, and Slack

About You

  • Strong experience with Typescript, or experience with object-oriented languages such as Java or C# and Javascript/Node.
  • Strong experience with observability tools, including metrics, structured logging and distributed tracing
  • You take ownership of your work and understand the importance of communication. You hold yourself to a high standard and help empower others to do the same.
  • 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.
  • Your code is a pleasure for your teammates to read and understand and you strive to ensure it is readable, testable, and maintainable.. When working in the codebase, you leave things better than you found them.
  • You embrace AI and find ways to use it to improve your work, rather than shying away from it.

Compensation

  • SF Bay Area, Los Angeles, Seattle, Portland, Boston, New York, and Washington, DC Metro: $187,000 - $220,000 USD
  • All other US Locations: $169,000 - $198,000 USD
  • Canada: $172,000 - $202,000 CAD

The ranges displayed reflect the target for new hire salaries, and within each range, individual pay is determined by your skills and experience, as well as relevant education. Your recruiter can share more and answer questions about the specific salary range during the hiring process.

Salary is just one component of Quo’s total compensation package. Your total rewards package will include equity, extensive medical coverage, a monthly lifestyle stipend, and a flexible PTO policy.

Who we are

We're a remote-first company with a culture of trust, autonomy, and action. As we rapidly grow, we're intentionally building communities in a handful of hub cities while continuing to hire great talent wherever they happen to live. If you're looking for a place to do your best work, we'd love to hear from you.

We are committed to creating an inclusive and diverse work environment. It is important that you are able to bring your authentic self to work every day. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
