About this role

Join an early-stage B2B SaaS company as a founding product engineer building an AI-driven pricing and monetization platform. You'll own end-to-end product modules, architect agentic AI systems, and help establish engineering practices while working directly with customers and leadership in a small, fast-moving team.

  • Architect agentic AI systems across web, conversational, and vendor integration surfaces using MCP-style servers
  • Move pricing and business logic to backend services while maintaining financial accuracy and data integrity
  • Build and maintain typed pricing ontology using Pydantic models for SKUs, propositions, personas, and pricing structures
  • Establish testing, observability, deployment, and performance monitoring practices for AI-driven features
  • Lead architectural reviews and mentor peers while shaping engineering culture and best practices

What they're looking for

  • Python and FastAPI backend development
  • Full-stack expertise with React and TypeScript
  • MongoDB or comparable database design
  • LLM integration and agentic AI workflow development
  • API design and versioned data models
  • B2B SaaS monetization (pricing, billing, CPQ concepts)
  • Financial logic and money-handling code correctness
  • Conversational and AI-native development patterns

Benefits

  • Founding-level equity stake in early-stage company
  • End-to-end product ownership and architectural autonomy
  • Direct collaboration with customers and leadership
  • Opportunity to shape engineering culture and practices
  • Work on cutting-edge AI agent integration
  • On-site location in San Francisco
