Senior Platform Engineer, Backend

Small businesses represent 99.9% of all companies, yet they're still forced to choose between clunky, outdated enterprise phone systems or their personal phones.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 90,000 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 Platform Engineer, Backend at Quo, you will spend a majority of your time coding, architecting, and owning moderate to complex platform 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 designing and delivering on small/medium size projects end-to-end.

This role focuses on backend systems and platform safety, with an emphasis on improving developer workflows and reliability. You will work in close partnership with Platform Infrastructure Engineers to build and evolve a platform that is scalable, reliable, and safe by default for product engineers.

Some Of The Things You’ll Do

Design, build, and own backend platform systems and shared capabilities that support engineering teams across Quo.

Define and evolve developer workflows and platform tooling, including CI pipelines, shared libraries, and internal tools.

Partner closely with Platform Infrastructure Engineers on modern deployment workflows and rollout strategies, evolving approaches as we learn and scale.

Own and improve database safety practices, including tooling, standards, and review processes for Postgres and SQL migrations.

Work with engineering and customer support teams to surface actionable operational insights and internal tooling that improve incident response and customer experience.

Build and improve observability across backend systems using metrics, structured logging, and distributed tracing.

In any of these areas, you’ll have the opportunity to tackle impactful challenges and help build scalable backend systems that support a growing user base.

Technical Stack And Tools

We use Kubernetes (EKS) on AWS to orchestrate our infrastructure setup and deployment. We utilize CloudFlare services to route, accelerate and protect our services. Our backend is built on Node using Typescript. The overall architecture is event-driven microservices with RabbitMQ and Temporal at the center of it all.

We use a variety of databases for different purposes: Postgres (including Aurora and Supabase), Cassandra, Snowflake, turbopuffer, Mongo, Elastic, and Redis.

We design and operate public API ingress and routing using cloud-native load balancing and application-level services.

We use Retool for some internal support applications.

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.

You are curious. You seek to understand the ‘why’ behind things so 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.
