I’m partnering with a stealth-stage AI startup that’s building next-generation consumer AI agents. They’re looking for a Backend Engineer to join onsite in San Francisco and play a key role in shaping the core product and translating advanced AI research into production-ready systems.

• Ensure observability, performance, and reliability across distributed systems
• Deliver fast, reliable solutions informed by real user feedback

What we’re looking for:

• 5+ years building and operating production backend systems in fast-paced, product-driven teams
• Strong fundamentals in distributed systems, API design, and reliability
• Fluent in Python and TypeScript/Node.js; experience writing testable, scalable, maintainable code
• Experience with Postgres/MySQL, Redis/Kafka, cloud infrastructure, Docker/K8s, and CI/CD pipelines
• Familiarity with AI/ML pipelines, embeddings, and LLM tool integrations a plus
• Proven ability to move fast, iterate, and deliver high-quality production systems

Why this role is exciting:

• Early-stage impact: define how AI products are built and scaled
