Node.jsTypeScriptPostgres
Role Overview
You’ll be a core technical founder building the backend systems and infrastructure that power Known - from the APIs that will serve millions of requests, to the real-time communication pipelines that enable voice and text conversations, to the data architecture that supports intelligent matching at scale. You’ll design systems that are reliable, performant, and ready to grow with our user base.
You’ll work closely with the founding team (AI/ML, fullstack, product, and design) to architect backend services that handle complex workflows — streaming LLM responses, batch matching jobs, payment processing, and real-time chat — while maintaining simplicity and developer velocity. This is a high-ownership role where you’ll make critical infrastructure decisions and set the technical foundation for Known’s growth.
