Founding Full Stack Engineer — Subconscious.ai

Location: Remote

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
