Founding Full Stack Engineer - Subconscious.ai

Compensation: Founding-level equity

About Subconscious

We're building the interface layer for understanding human behavior. Subconscious.ai lets companies simulate synthetic populations to test ideas, predict outcomes, and uncover why people make decisions - all powered by causal AI.


Trusted by teams at SpaceX and PwC, we replace slow, expensive research with real-time behavioral simulation. Backed by OpenAI and Sequoia insiders, we're scaling fast and looking for a full-stack engineer to help us push the frontier.

The Role

Own the product experience for a platform that visualizes the decision graph of humanity. You'll design interactive tools that let users explore complex simulations, test incentives, and run experiments - all through a sleek, fast interface.


This isn't just about frontend polish - it's about helping define a new UX primitive for how people interact with AI.

What You'll Do
  • Build and scale the core frontend with Next.js, React, Tailwind CSS, and TypeScript
  • Architect real-time, collaborative interfaces for simulation and behavioral insight
  • Integrate deeply with Auth0, Langchain, OpenAI, and custom LLM pipelines
  • Shape product vision, design, and architecture alongside the founding team
  • Help define the "copilot" UX for researchers, strategists, and decision-makers
You Might Be a Fit If You
  • Have 3+ years building production-grade apps with React/TypeScript/Next.js
  • Thrive on complex data-rich UX - dashboards, simulation tools, collaborative UIs
  • Love turning messy ideas into elegant products, fast
  • Are curious about AI/ML (technical background not required, but interest is key)
  • Want to build something new, not just better
  • Bonus: Experience with Liveblocks, ReactFlow, or data viz libraries like D3, Recharts, or Deck.gl
Our Stack
  • Frontend: Next.js, React, Tailwind, TypeScript, Auth0
  • AI/Backend: FastAPI, Langchain, OpenAI, Python, AWS
  • Infra/Tools: GitHub, Sentry, Vercel
Why Join Now
  • Founding equity in a product defining a new category
  • Zero bureaucracy, full creative input
  • Build something people didn't know was possible - until they use it
  • Help shape how humanity interacts with synthetic minds
How to Apply

Email with your resume, GitHub/portfolio, and a short note on why causal AI or simulating behavior excites you. Keep it weird, keep it smart.
