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.
We were accepted into Endless Fronteir Labs, Creative Destruction Labs, and Antler. You will have exposure to the 3 most competitive, 1% acceptance rate, top-level accelerator programs.
Backed by OpenAI and Sequoia insiders, we’re scaling fast and looking for a frontend 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.
We need at least 3 years of experience and those interested in Causality and Human Behavior. We are looking for Real Founding Engineers who can work closely with our enterprise customers to build magical UX experiences. Engineers who are familiar with AI Engineering and Agentic frameworks such as Agno, OpenAI Symphony, crewAI, Langchain, and others.
This isn’t just about frontend polish or vibe coding, it’s about helping define a new UX primitive for how people interact with their business.
RESPONSIBILITIES
Develop and optimize simulation models, including designing experiments, analyzing results, and improving accuracy, speed, and consistency.
