The role

Governments make decisions that affect millions. This applied AI lab is building a decision-intelligence platform to help them get it right. They're creating society-level simulations, helping policy teams research evidence, model population responses, and produce auditable, decision-ready documents. Backed by leading investors, this isn't about replacing human judgment, but augmenting it with transparency and rigor.

You'll be the first design engineer, owning the entire front-end experience. This is a hybrid role: part designer, part front-end engineer. You'll work directly with the founders, shaping the product's visual and interaction language from day one. This isn't just executing specs; it's defining them, from Figma prototypes to production-ready React code. You'll build the design system, not just use one.

The work

• Design and prototype user interfaces in Figma, translating complex policy workflows into intuitive experiences.
• Ship production-ready front-end code in React, owning features from concept to deployment.
• Build and maintain the core design system, ensuring consistency and accelerating team velocity.
• Collaborate directly with founders, policy advisors, and civil servants to define product direction and user needs.
• Set the visual and interaction language for the entire platform, influencing product, marketing, and company design.
  
  

What You Bring

• 2-3 years experience building production interfaces, owning both design and front-end development.
• Proven ability to ship front-end code in React.
• Comfort navigating ambiguity, sparse briefs, and evolving priorities in an early-stage environment.
• A genuine interest in solving complex problems within the public sector.
