Senior Platform Engineer, Infrastructure at Quo – California

About the role
As a Senior Platform Engineer, Infrastructure at Quo, you will spend a majority of your time coding, architecting, and operating 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 cloud infrastructure, networking, and platform safety, with an emphasis on operating scalable, reliable systems. You will work in close partnership with Platform Backend 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, deploy, and operate large-scale, cloud-native distributed systems, owning the infrastructure foundations that underpin Quo’s backend services and deployment workflows. Define and help implement core platform patterns that enable reliability, scalability, and safe change over time.
• Build and operate core observability, monitoring, and telemetry infrastructure, working with engineering and customer support teams to ensure systems are diagnosable, incidents are actionable, and operational signals meaningfully improve customer experience.
• Partner closely with Platform Backend Engineers and product teams to adopt best practices, evolve platform capabilities, and introduce new technologies in a way that balances reliability, velocity, and long-term maintainability.
• 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
