We’re on a mission to reinvent how AI understands people — not through CVs or data points, but through story, reasoning, and curiosity. We’re building systems that listen, interpret, and understand why people say what they say. The goal? Create AI that perceives human potential, not just human input.

• Fast, intuitive interfaces that make human-AI interaction feel alive
• Rapid prototypes that turn bold ideas into working productsScalable infrastructure for experimentation and learning

You’ll Thrive Here If You

• Come from a disruptive, fast-moving environment
• Have helped launch or shape new ideas, products, or technologies
• Think in systems and build with elegance
• Believe speed drives creativity
• Are curious about human cognition and behaviour
• Value truth, craft, and collaboration over hierarchy

What You Bring

• Deep fluency in TypeScript and modern frameworks
• Experience with vector databases and embeddings
• Strength in LLM fine-tuning or multimodal reasoning
