Known - Backend Engineer- San Francisco, CA (In-Person)
- $200k-$350k Cash + Equity
About the RoleWe're looking for exceptional backend engineers to build the infrastructure that powers Known's core product, from real-time conversational AI to intelligent matchmaking and autonomous agents.
This is a unique opportunity to contribute to the technical foundation for an AI-native consumer product. You'll work across distributed systems, data infrastructure, and AI integrations, solving complex engineering problems at the intersection of large-scale consumer applications and frontier AI.
What You'll DoIt's up to you to decide what part of the backend stack you're most excited about working on.
This could be:
- Designing and scaling the backend services, APIs, and infrastructure that power Known's core consumer experience
- Building real-time systems that support conversational AI, voice interactions, and agentic workflows
- Architecting data pipelines and storage systems to support matchmaking, personalization, and machine learning
- Developing reliable, low-latency services that connect our AI agents to real-world actions and third-party integrations
- Improving the performance, reliability, security, and scalability of our systems as we grow to millions of users
You will own systems end-to-end, from architecture and implementation to deployment, monitoring, and scaling.
Requirements- 4-6 years of experience designing, building, and deploying production backend systems
- Strong proficiency in at least one backend language (e.g., Python, Go, TypeScript, Java)
- Experience designing APIs, distributed systems, and scalable service architectures
- Experience with relational databases, caching, asynchronous processing, and data infrastructure
- Experience with cloud infrastructure and deployment (e.g., Docker, Kubernetes, AWS/GCP)
- Strong product intuition and a bias toward shipping, iterating, and taking ownership
- You want to build technology that could lead to a million marriages and babies
