Frontend Engineer

Stoneborn Technologies

Stoneborn Technologies automates the infrastructure of risk capital.

We are a small team of former Palantir and Swiss Re engineers building AI-native systems to modernize the core operations of re/insurance.

Re/insurance still runs on spreadsheets, PDFs, and email. We build AI agents that replace this manual backbone with code. Our first product is in pilot at leading re/insurers. With the first conversion agreed and funding secured, we are scaling fast to capture the full value across end-to-end operations.

You will own the front-end and the UX for our client-facing workflows; responsible for helping humans intuitively collaborate with AI agents around complex operational processes.

You’ll work closely with the backend team, getting your hands dirty where required, and iterating directly with business users.

• Strong experience with React and Typescript
• Great UX taste and a bias for simplicity

• High ownership mindset, pragmatism and speed

• Your code becomes core production infrastructure used by clients
• Proven product traction and high-value roadmap
• Small team with direct access to decision-making and clients
