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
- Lead the full vertical development of features, from initial scoping and system design to frontend interactions and production deployment.
- Architect robust data models and API contracts in TypeScript and Python to ensure the simulation engine remains fast and reliable at scale.
- Partner closely with the CTO and design team to translate complex simulation capabilities into intuitive, high-performance product features with exceptional craft.
Who this is a fit for
- 5+ years of software engineering experience with a track record of owning features end-to-end and making critical architectural decisions in production environments.
- Expert-level proficiency in TypeScript and the modern web stack, with strong skills in Python and advanced PostgreSQL schema design.
- Exceptional product taste and attention to detail, with a mastery of system performance, API latency, and fluent use of AI coding agents.
Why this role is remarkable
- Direct technical ownership and architectural influence over a platform used by the world’s largest financial and technology organizations to make high-stakes decisions.
- Backed by elite investors including Y Combinator, Point72, and Kindred Capital, alongside industry pioneers from DeepMind and Sequoia Scout.
- Work at the absolute frontier of AI, turning complex simulation data into high-performance, polished products that deliver value in hours rather than months.
