RESPONSIBILITIES

What you will do

  • Design and implement graph algorithms using Neo4j to visualize and navigate complex relationship data into actionable goals.
  • Build and refine the AI sequencing layer that determines optimal outreach timing and personalized coaching for users.
  • Own the full-stack development using React/Next.js, Node.js, and TypeScript, from high-level architecture to polished frontend onboarding flows.

CANDIDATE PROFILE

Who this is a fit for

  • Proven track record of shipping consumer-facing products end-to-end, ideally as a founder or early engineer at a high-growth startup.
  • Deep fluency in TypeScript and modern React/Next.js, with the ability to manage complex data models across PostgreSQL and Neo4j.
  • High agency individual who thrives in ambiguity, values in-person collaboration in San Francisco, and prioritizes product-market fit over rigid processes.

WHAT MAKES IT REMARKABLE

Why this role is remarkable

  • Founding engineer status as the first full-time hire, inheriting a beta-stage codebase with total ownership over the future architectural roadmap.
  • Build a category-defining product alongside a founder who previously scaled a creator ecosystem from 2,000 to 4 million users.
  • Direct impact on solving the "hidden job market" problem by engineering sophisticated relationship graphs and conversational AI interfaces.
