Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Design and develop an interactive, game-like website that simulates a living world populated by AI agents. Own the entire process from initial concept and design to final production and deployment.
Candidates must have a proven track record of shipping a game and strong command of modern web technologies. Ability to create performant, interactive browser experiences and a strong ownership mindset are essential.
Pilots don't train with real passengers. Actors don't rehearse with real audiences. Yet, the most consequential decisions in society are often pushed straight to production.
Simile is changing that. We have built the first AI simulation of society, populated by generative agents based on real humans. Our research pioneered the field of AI-based simulation, proving it is possible to model human behavior with high accuracy. Today, we are developing a Foundation Model to predict human behavior in any situation, at any scale.
We are backed by $100M in funding led by Index Ventures, with participation from Hanabi, A*, Bain Capital Ventures, and AI visionaries including Andrej Karpathy, Fei-Fei Li, Adam D'Angelo, and Guillermo Rauch.
Here’s the problem. Every AI company website is the same: a hero image, a tagline, some customer logos, and “Book a Demo.” We build living worlds for a living, so our website should be a place for exploration.
We’ll give you a town full of simulated people. You’ll turn it into a living, breathing place for people to discover. None of this exists yet, but you’ll build it. That’s the job: build us a website that feels like Smallville. Populate it. Make it move. Make the people who land on it want to stay, play with it, and send it to someone else.
Build the world: Design and ship a website that feels like Smallville — interactive, alive, and worth exploring rather than a static landing page.
Populate it: Bring our simulated people into the browser and give visitors a world to wander through, not just a page to scroll.
Make it move: Create the motion, interactivity, and game feel that turns a visit into play.
Own it end-to-end: Take the experience from blank canvas to production, making the design, engineering, and craft calls along the way.
Make it spread: Build something people want to stay in, play with, and send to a friend.
Game Sense: You’ve shipped a game. A jam entry, a weird side project, anything real that people actually played. You know what makes play feel good.
Web Craft: Strong command of modern web technologies and the ability to build performant, interactive experiences in the browser.
Judgment: You know the difference between an interactive thing that feels alive and one that feels clunky.
Ownership Mindset: A desire to own the whole thing end-to-end.
You’ve built a game that found a large audience, or shipped commercially.
You can make pixel art yourself — sprites, tiles, little worlds — or direct artists who can.
You’re curious what AI agents get up to when you hand them a world.

Simulating human behavior with AI. Our vision: ask anyone any question at any time.
Simile is a human simulation company: we develop AI models that estimate what people will do in new situations. By drawing on rich ground truth information about real people, we build models that extrapolate their behavior and attitudes. To achieve this, we are building a foundation model of human behavior—one that knows much more about human behavior than what's available on the web for traditional large language models. We tie this modeling together with a product that enables people to author simulations to answer any question they need. Our vision is to empower people to ask any question to any person, at any time. Our customers are using Simile to explore potential new concepts, understand their customers more deeply, and gather instant insights for faster, better decisions. Our leadership includes: - Joon Sung Park (CEO): TED AI speaker, Stanford PhD, whose research invented AI simulation of human behavior - Percy Liang (Chief Scientist): coined the term "foundation model", Stanford Professor of Computer Science, co-founder of Together.ai - Michael Bernstein (Chief Product Officer): Stanford Professor of Computer Science, nationally bestselling author, interaction designer - Elaina Yallen (Chief Customer Officer): Previously Head of Product and Engagement at Hebbia, COO at Valence
