Role overview
Artificial Societies Ltd (operating via the domain societies.io) is an AI startup that builds networks of AI personas to simulate entire human societies and stakeholder opinions for behavioral research and market testing. Using AI-generated synthetic personas connected in social graphs, the platform runs simulations of how defined audiences interact, influence one another, and respond to messages, products, campaigns, or policies, then returns quantitative scores and qualitative outputs such as written summaries, comments, and example reactions. This enables marketers, creatives, researchers, and policy makers to forecast real-world outcomes, refine messaging and content, test marketing strategies pre-launch, and explore complex social dynamics in a virtual environment that mimics real-world behavior. The company positions its simulations as a modern alternative to traditional market research, supporting use cases in marketing, sociology, economics, urban planning, and broader decision-making where understanding group reactions and idea propagation is critical.
What you will do
- Own the complete lifecycle of product features, from initial scoping and database modeling in Postgres to shipping polished TypeScript frontend interactions.
- Partner with research engineers to integrate the latest simulation engine capabilities into the user-facing product, ensuring speed, reliability, and high-stakes accuracy.
- Collaborate on product vision and design, pushing back with technical insights to ensure every feature feels intuitive and performs flawlessly at scale.
Who this is a fit for
- Has at least 2+ years of experience as a software or product engineer, with a proven track record of shipping end-to-end features to users.
- Demonstrates mastery of TypeScript and proficiency in Python, with a strong instinct for product taste, latency, empty states, and micro-interactions.
- Possesses an ownership mentality, comfortable using AI coding agents like Claude Code to accelerate development while maintaining a high bar for architectural integrity.
Why this role is remarkable
- Work directly with the CTO and CPO in a lean, high-bar environment where ideas win based on merit rather than seniority.
- Build at the frontier of AI with backing from Y Combinator, Point72 Ventures, and Kindred Capital, alongside investors from DeepMind and Sequoia.
- Drive massive impact by putting frontier AI into the hands of Fortune 500 firms, replacing slow, expensive traditional research with instant, accurate simulations.
