Senior Platform Engineer, Backend at Quo – California

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.
• Strong experience with observability tools, including metrics, structured logging and distributed tracing.
• Experience working with SQL databases, particularly Postgres, including schema design and migrations.
• Experience with CI/CD systems and improving developer workflows.
• Experience working with GraphQL in federated environments.
• You find joy in replacing mundane processes and tasks with automation, AI, and applications.
• You are creative and flexible when selecting tools and solutions.
• 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 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.
• You embrace AI and find ways to use it to improve your work, rather than shying away from it.
